Foreword
The Internationaler Verein für Technische Holzfragen e.V. -
iVTH (International Association for Technical Issues Related
to Wood) has been dedicated to applied timber research for
almost 70 years now. Current challenges facing the field are
the supply of timber, the change in the range of raw timber
available from soft to hard woods, environmental issues and,
of course, continuing development in timber product cha-
racteristics and production technologies. During the reporting
period 2013/14, the association has led collective industrial
research teams with around 20 projects reflecting these sub-
jects. In 2015, six new projects are already dealing with issues
of importance to forestry and timber management.
The subject of the recycling of wood products is once again
gaining significance. At the same time it is worth taking a look
beyond our own field, specifically into the field of plastics.
These synthetic polymer materials are suitable for countless
applications thanks to their diversity, performance and, above
all, durability. In contrast to other materials they generally do
not rot, corrode or erode. This means that they can be used
in areas which are impossible or at least problematic for other
materials such as wood, paper, steel or concrete.
Today at least 150 million tonnes of plastic are produced
around the world each year. Many types of product would be
almost unimaginable without plastics. However, critical voices
have been raised in recent times. The very durability of most
plastics has been recognised as being their most problematic
characteristic. Added to this are constituents of plastics such
as softeners, flame retardants and other problematic additives
which can have a negative impact on the environment. When
not disposed of correctly, they also contribute increasingly to
the pollution of rivers and beaches and are carried by cur-
rents far out into the oceans where they present a danger to
seabirds and sea creatures. Biodegradable plastics have been
developed but have not so far been established in the industry
to any great degree. Whether this will change in the future
remains to be seen.
Wood is also a polymer material but as a natural product it has
built-in biodegradability. This means that wood and products
made from it will not accumulate in a similar way. Neverthe-
less, the timber industry, which itself produces a wide range
of composites using plastics, will not be viewing the problems
associated with plastics with any degree of schadenfreude
because as well as competition there are also synergies. Many
timber products make use of plastics and composites such
as furniture, doors, laminate flooring and WPCs exploit the
advantages of both groups of materials.
The iVTH will follow with interest the continuing discussion
surrounding disposal and, where required, will initiate and
support collective industrial research projects where timber
products are also concerned. This annual report includes one
such project already: collective industrial research project
17411N „Recycling of Wood-Polymer Composites (WPC) as
demonstrated by the example of decking planks“.
Having taken this short excursion into the world of plastics,
we would now like to thank the iVTH team for their hard work
and our colleagues on the executive committee and advisory
board for their support and essential supervision of the work
of the association. I hope that you find this annual report of
interest.

A Profile of the Association
The International Association for Technical Issues Related
to Wood – iVTH - was founded in 1946 on the initiative
of timber researcher Wilhelm Klauditz and what was then
Braunschweig‘s state forestry administration. Since then, we
have been promoting links between technical and scientific
ideas whilst taking into account economic conditions.
As a non-profit association, the iVTH promotes research and
development in the fields of wood and wood-based panels
as well as related areas including, for example, adhesives,
construction, testing and standards. We have a history of
acting as an intermediary between science and practice that
stretches back over almost 70 years and is based in part on
experience in forestry and the timber industry.
For us, helping to shape the future means taking the findings
from successfully-completed research projects and using it to
grasp, develop and promote new ideas. This also includes esta-
blishing initiatives to advance our knowledge of timber and its
use as a raw material and to communicate this to others.
Join us in maintaining this knowledge transfer for future
generations and shaping the future with a raw material fit for
our times.

The AiF was founded in 1954 as a non-profit association and
has grown to become an alliance of around 100 research
associations with partners from business, science and go-
vernment managing research funding via a variety of funding
instruments along the whole length of the value-added chain.
Industrial collective research acts as the bridge between funda-
mental research and industrial application. The German Federal
Ministry for Economic Affairs and Energy (BMWi) provides
public funds for industrial collective research. The objective of
the programme is to balance out the structural disadvantages
of small and medium-sized enterprises (SMEs) in the field of
research and development. The intention is to make it easier
for SMEs to access technological advances, making them more
internationally competitive; this takes place within a single
business sector but increasingly also across all sectors under
the umbrella of the AiF research associations. The research
projects focus on the needs and interests of the business with
the business being fully involved. Depending on the issue
being researched, the cooperative, practice-orientated research
activities are carried out primarily by universities and non-
profit research institutions with close links to business. This
means that parallel fields of research can be developed to the
pre-competition stage with technical and economic risks being
shared between several institutions. The results of the research
are openly available to any interested party.
The iVTH has been a full member of the AiF since 1958. The
AiF is the sole coordinator and organiser of pre-competition
collective industrial research which is why only AiF members
are able to apply to the BMWi for public funding for research
projects as part of practice-orientated fundamental research.
In order to make an application, businesses or research bodies
direct their suggested subjects for industrial collective research
projects to an appropriate research institution; for wood-
related issues, for example, it might be the iVTH. The range of
subjects covered by AiF research associations includes future
technologies of relevance to SMEs, from biotechnology to new
materials and efficient use of resources.

AiF facts and figures
�� Since its foundation in 1954 the AiF has directed around
€10 billion into developments and innovations.
�� Over 200,000 research projects have been realised.
�� 1,200 research institutes have participated over the last five
years alone in industrial collective research projects.
�� Around 1,200 experts from business and science work
ensure the quality and practical relevance of the research.
�� Close to 50,000 primarily small and medium-sized enter-
prises benefit from the results of research conducted under
the aegis of the AiF.
AiF projects conducted by the iVTH in 2013
The iVTH supports research projects of interest to small and
medium-sized businesses. The Corporate Finance Codex
enacted in 2011 means that research associations may not
draw remuneration from the research bodies for research
funding from the BMWi. This means that the costs for advice
and support as well as AiF membership subscription fees are
covered solely from membership subscriptions, donations and
one-off contributions to the association.
In 2013, the iVTH supported 20 industrial collective research
projects and one CORNET project. The new industrial coll-
ective research project „Simulation-aided development of
lightweight, medium-density fiberboard (MDF)“ was started
on 1 January 2013. Work on the project will continue until
the end of 2015, carried out by the Fraunhofer Institutes WKI
and ITWM. In July 2013, the Fraunhofer Institutes WKI and
IBP began the project „Development of models to generate
hygrothermal characteristic values of wood-based panels for
the digital simulation of component behaviour“, also as part of
the industrial collective research project.
AiF projects conducted by the iVTH in 2014
In 2014, the iVTH supported 17 industrial collective research
projects including two new projects. In January 2014, research
work began at the Fraunhofer WKI on the project „Product
analysis and development of a process for testing the adhesi-
on of laminate flooring taking into account behaviour when
renovated with water-based coatings“. One further industrial
collective research project was approved on 01.05.2014. The
Chair of Materials Science and Construction at the Technical
University Munich is responsible for leading the project. The
brief title of this project is „Eccentric and neighbouring bre-
akthroughs in glued laminated timber girders“.

Activities 2013/2014
From 6 to 10 May 2013, the iVTH and WKI once again ap-
peared as exhibitors at LIGNA in Hall 27/J 35 at the Messege-
lände exhibition grounds in Hanover. They presented the work
of various research institutions, such as that of the Technical
University of Dresden on moulded wood as hollow sections for
the construction industry or three-dimensional curved shells
e.g. for architecture and design. Holzforschung München con-
tributed the prototypes of a „lightweight fire safety board“.
Ligna 2013 Bayern Innovativ Cooperation Forum „Wood As a New Material“ 6 November 2013, Regensburg
Together with several Bavarian wood and forestry institutions,
the International Association for Technical Issues Related to
Wood – iVTH – took part in the cooperation forum „Wood As
a New Material“ hosted in Regensburg by technology transfer
centre „Bayern Innovativ“.
The forum was held in the historic Salzstadel building and
with over 200 participants was not only very successful but in
a series of high-quality introductory and expert presentations
also provided information on current developments in wood-
based new materials beyond conventional ways of using and
exploiting timber.
Professor Klaus Richter from Holzforschung München first of
all gave an introduction to the challenges and trends in new
materials. After providing information on the importance of
the efficient use of resources in innovative products and cur-
rent developments in materials in the paper industry, Ralf Pol-
lmeier explained the innovative potential of laminated beech
veneer lumber in the construction industry. A panel discussion
went on to provide further insight into this subject. iVTH Chair-
man Professor Rainer Marutzky then introduced seven expert
presentations of research results into innovative products deve-
loped through biomineralisation and structure resolution right
through to the nano scale or the foaming of wood.
Speakers also provided insights into new applications for
wood-based panels in the field of personal protection and in
the automotive industry as well as opportunities for the use of
bamboo. The forum was accompanied by an industry exhibiti-
on. Here, the stand held by the Fraunhofer Institute for Wood
Research WKI with examples of new findings and products
was one which provoked lively interest among participants.

20 /21 March 2014, Braunschweig
Together with the Fraunhofer Institute for Wood Research
WKI, the iVTH held its now traditional „Wood Research Days“
in Braunschweig on 20 and 21 March 2014.
This year‘s subject „Emissions from construction materials
and furnishings for interior spaces/VOCs, formaldehyde and
fragrances“ provoked strong interest among the 110 parti-
cipants from business, research institutions and government
agencies. A wide-ranging programme was once again on offer
with 16 expert presentations. Since emissions in indoor spaces
are gaining increasing significance in terms of standards and
legislation, presentations were concerned not only with the
latest research findings but also on national and European
regulations. The perspectives of the buildings inspectorate and
the federal environment agency were particular cause for lively
discussion.
In addition, strategies and processes for the minimisation of
emissions and possibilities for product monitoring were pre-
sented. Questions concerning the evaluation of the emissions
released by construction products from a hygiene point of view
were also thrashed out in a panel discussion and the need to
act where statutory and standards regulations are concerned
was explained.
Participants were able to continue discussions in a relaxed
atmosphere during an evening meal in the lounge of the
Braunschweig Residenzschloss.

Activities 2013/2014
Bayern Innovativ and the iVTH together hosted the 2nd coo-
peration forum „Bonding of Wood and Wood-based Panels“
Almost 250 participants from research and business enjoyed a
wide-ranging programme with 20 expert presentations at the
Festung Marienberg conference centre in Würzburg.
Presentations focused on findings from a variety of current
research projects by research institutions in Germany, Austria
and Switzerland, new solutions for bonding in industrial prac-
tice and advances in the development and application of low
emissions adhesives for wood products.
An evening reception with perfect weather in the garden pa-
vilion of the Juliusspital in Würzburg provided a good oppor-
tunity in relaxed conversation to further explore impressions
gained from the conference, to build on existing contacts and
to make new ones.
The success of the event encouraged the two hosting institu-
tions to announce a 3rd cooperation forum for the 21 and 22
June 2016, once again in Würzburg.

German Wood Preservation Conference 2014 in Braunschweig
On 18 and 19 September 2014, the iVTH organised for the
first time on behalf of the Technical Committee On Wood Pre-
servation the German Wood Preservation Conference. Around
100 participants from research and business in Germany and
abroad gathered in Braunschweig‘s Stadthalle. The 17 presen-
tations spanned a wide arc from science to practice.
The subjects covered at the event included legal aspects
surrounding wood preservation and standards as well as the
development of new technologies in the field of wood preser-
vation. Numerous examples from practice demonstrated the
significance of wood preservation in construction for the pre-
vention of damage. Participants were also shown a wide range
of fungi and moulds which cause damage to wood as well as
images of the damage they cause. Following the individual
presentations, conference participants enjoyed plenty of time
for discussion.
The evening event took place in a cosy Braunschweig pub.
Participants were able to reflect on the first day, make new
contacts and build on existing ones during the convivial barbe-
cue.

Organisers from the Fraunhofer WKI and the EPS can look
back on the successful 9th European Wood-based Panel Sym-
posium which they organised in Hanover from 8 to 10 October
2014 with the support of SasolWax GmbH and the iVTH. The
Maritim Airport Hotel once again provided a comfortable
location for the conference at which around 260 interested
participants from science and practice in Germany and abroad
gathered to look into the subject of wood-based panels. Ladis-
laus Döry, President of the European Panel Federation, opened
with a presentation on the current situation in the European
wood-based panel industry. There followed 23 presentations
over two days shining a light on the situation of the wood-
based panels sector and related fields around the world. In
many countries, the shortage of raw materials is becoming an
urgent situation which can be compensated by the use of re-
cycled wood in Europe and Japan and the use of fast-growing
plantation trees in South America.
9th European Wood-Based Panel Symposium -
Successful symposium in Hanover
At the close of the conference, the organisers expressed their
thanks for the outstanding organisation and announced the
10th European Wood-based Panel Symposium, which will be
taking place for the first time in Hamburg in October 2016.
Speakers from the fields of plant engineering and measure-
ment technology presented individual solutions for the effici-
ent use of resources. Presentations on the continuing deve-
lopment of wood-based panels and adhesives were a further
key aspect of the event. In the field of emissions, the speakers
provided informative presentations on national efforts to set
standards and possibilities for monitoring. The symposium,
with its interesting technical contributions, was rounded-off
in dignified style with an evening reception at the invitation of
Sasol in Hanover‘s Neues Rathaus.

teaches at the ETH Zürich, was awarded the Wilhelm Klauditz
medal of the International Association for Technical Issues
Related to Wood at the 2nd cooperation forum „Bonding
of Wood and Wood-based Panels“ in Würzburg on 23 June
2014. The presentation was a way for the Braunschweig
association to honour the services of this scientist from Saxony
who specialises in wood research. The focus of his work is in
the fields of wood physics and wood technology as well as in
issues surrounding the bonding of wood.
Professor Niemz has shared his scientific knowledge and the
results of his research with other experts in over 500 publica-
tions, of which around 300 have appeared in respected jour-
nals and in over 200 presentations to professionals in the field.
He has also been significantly involved in 10 specialist books,
either as author or editor.

9 October 2014, HWS Hannover
Dr. Hans Schroeder, former Head of Department at the Lower
Saxony Ministry for Science and Culture, was awarded the
Wilhelm Klauditz medal by the iVTH for his services to the pro-
motion of applied forestry and wood research. The ceremony
took place on 9 October 2014 during the evening event of
the 9th European Wood-based Panel Symposium hosted by
SasolWax GmbH at the Neues Rathaus in Hanover. Professor
Bohumil Kasal, Director of the Fraunhofer Institute for Wood
Research (WKI), presented the award to the laureate and gave
a brief insight into the work of Dr. Schroeder.
He has been a valued and recognised member of the board
of WKI and the advisory board of the iVTH since 2001. During
this period one of Dr. Schroeder‘s particular achievements was
to bring together the research institutions for the field of wood
and forestry in Lower Saxony. The Lower Saxony Ministry for
Science and Culture provided start-up funding which enabled
him to effect an initial cooperation leading to a variety of
cooperative research projects. The network developed into
a research and development cluster made up of members
from the timber industry and science in lower Saxony, Saxony
Anhalt and Northern Hesse which encompasses the entire fo-
restry and timber value-added chain. The research institutions
involved came together in 2005 to form the lower Saxony
Competence Network for the Sustainable Use of Wood [NHN].
This promoted interdisciplinary and cross-institutional coope-
ration between its members and supported them to conduct
application-oriented research projects. Dr. Schroeder also
makes a dedicated contribution to this competence network as
a member of the economic advisory board.

Overview – Short Reports 2014
17iVTH-Report2013 / 2014
The text „Building and living with wood“ commissioned by the
DHWR German Wood Industry Council (Berlin) was published
in March 2013. Prof. Tunga Salthammer and Prof. Dr. Rainer
Marutzky convincingly present the advantages of living in
wood. The objective of this text is to inform project managers,
planners and those building with wood of the health and hy-
giene characteristics of wood and the diverse aspects of using
wood products in a domestic setting.
Publications
„Building and living with wood“ Practice Comments on Standard DIN 68800 in the BEUTH Commentary Series
At the start of 2013, Practice Comments on Standard DIN
68800 was published in the BEUTH Commentary Series. The
publishers are the Deutsche Institut für Normung (German
Standards Institute) and the International Association for Tech-
nical Issues Related to Wood – iVTH. The team of respected
authors, Dietger Grosser, Horst Hertel, Borimir Radovic and
Hubert Willeitner, give a detailed explanation of the imple-
mentation of the standard in construction practice and provide
useful notes on all relevant aspects.
The second, completely revised and updated edition of the
Beuth Commentary is an important addition to the new wood
preservation standard. The DIN 68800 series of standards
has been redesigned. In parts 1 to 4 it sets out central condi-
tions for wood preservation in an area where there is tension
between building longevity and the requirements for modern
standards of health and safety.
The book offers to all those using the standard:
�� extensive explanations of the new design of the standard,
�� comprehensive commentary on individual sections of the
standard,
�� transparent explanation of the background and context of
the standard and
�� the original text of all parts of standard DIN 68800.

The article below was published in March 2013 in the journal
„Hazardous substances – keeping our air clean, 73 (2013) No.
3 - March“ (Springer-VDI-Verlag GmbH & Co.KG) by M. Wen-
sing, B. Bliemetsrieder, A. Ligarski:
„Investigation into emissions from internal doors relevant to
indoor air in order to assess the behaviour of building products
with respect to hygiene, health and environmental protec-
tion“.
As part of collective industrial research project 16210 N/2 sup-
ported by the iVTH, promoted and financed by AiF and BMWi,
door frames and door casings conforming to standard EN
14351-2 were comprehensively tested for emissions relevant to
indoor air quality using the test chamber method.
Since 2011 the iVTH has included reporting via the Internet
amongst the possible ways of passing on information from
research to industry and the scientific community.
Depending on what is happening at the time, the newsletter
deals with subjects from the forestry and timber industries and
related fields as well as, for example, research findings and
biographies. Reports on collective industrial research projects
also provide information on the significance and benefits of
these research grants for businesses in the field of wood. The
iVTH newsletter is published at regular intervals.

ECOPRESSWOOD is a research project of the 7th Framework
Programme of the European Union which was started on 1
May, 2014. The joint project involves three European research
bodies, including the Fraunhofer Institute for Wood Research
WKI in Braunschweig, working to develop a biologically based
and formaldehyde-free binding agent for wood-based panels.
The background to the project is the classification of formal-
dehyde in category 1B (carcinogen) „Substance with probable
carcinogenic potential for humans“ and 2 (mutagen) by the
European Chemicals Agency‘s Committee for Risk Assessment.
Residues from biodiesel production are to be the source mate-
rial for the new adhesive. The project also intends to test the
use of ceramic nanoparticles for reinforcing the adhesive.
The iVTH together with other research associations and wood
federations from Austria, Croatia, Ukraine and Italy is sup-
porting the project by communicating research findings to
interested small and medium-sized industrial enterprises. The
coordination of the project is the responsibility of Spanish
furniture technology centre CETEM in Yecla (Murcia).
Current Research Projects
EU Project ECOPRESSWOOD
In order to gain an overview of the way that the industry uses
binding agent resins and the wishes and needs surrounding
the subject, a survey was undertaken through the associa-
tions in the first year, in accordance with the project plan. The
research bodies are currently working on synthesising suitable
binding agent polymers. The research work is on schedule.
�Πwww.ecopresswood.eu
21iVTH-Report2013 / 2014
The project began in September 2012 at the Fraunhofer WKI
and is scheduled to run until 31 August 2015.
Wood-Plastic Composites (WPC) consist of particles contai-
ning lignocellulose and thermoplastics (primarily polyethylene,
polypropylene or PVC) and additives. The material is a biocom-
posite and the wood component can be as high as 75%. The
product is generally very durable making it ideally suited for
use as decking planks, a significant application.
The WPC manufacturing sector in Germany is relatively young
in comparison to the classic wood-based panels sector. With
a production volume of 260,000 t in 2012 it is successfully
delivering new biomaterials in Europe (nova-Institut 2014).
WPCs are fundamentally recyclable since the thermoplastic
polymers used mean that they can be ground, melted down
and re-extruded or processed in some other way.
Some German WPC manufacturers offer free returns of their
own products. For small volumes of WPC requiring disposal,
most manufacturers recommend treating as household waste;
for larger volumes they suggest either recycling as scrap wood
or incineration for energy. Since WPC contains over 50%
wood it is regarded as scrap wood in terms of recycling, in line
with scrap wood regulations. However, there is as yet no
concrete legal categorisation of WPC since WPC is not expli-
citly named in the legislation. It may be assumed that old WPC
profiles can be used to manufacture new products after the
end of their useful life.
In the long term, the supply of petroleum-based plastics and
therefore also WPC will become more limited and therefore
more expensive, which means that the use of recycled mate-
rials is a hot topic for the WPC industry. From an economic
point of view, cutting costs by using re-granulate instead
of fresh raw materials makes sense. Improved marketing of
WPC‘s recyclability and the ecological advantages of the mate-
rial as well as a solution for the problem of disposal could help
to strengthen the German market.
The project is intended to increase competitiveness for SMEs in
the sector by using a proportion of recycled WPCs in products
of other industry branches such as the plastic and wood-based
panel industry. In addition, the intention is that old WPC‘s can
be reused within the original manufacturer‘s operation and
that old WPC‘s can continue to be used for the extrusion of
new decking planks. This process is intended to establish the
basic technical feasibility of the recycling of WPCs. Alongside
facade profiles, the decking plank is so far the only WPC
product for which concrete requirements exist which means

that it can be used as an example to identify the limits of its
recyclability.
The project has investigated the effects of adding stabilisers
and non-WPC recyclate in various proportions and adding 2/3
fresh WPC to the WPC recyclate. The experiments took place
using Design of Experiments, DoE. DoE offers the advantage
that several parameters (three in this case) can be simulta-
neously and systematically varied to levels established before
the start of the experiment and the effects of the individual
parameters can be clearly proven using mathematical methods.
Using DoE shortens the time required for the experiments and
interactions between parameters can be recognised.
In the investigations carried out so far, it has been shown that
WPC has a high potential for recycling and that a good level of
stabilisation is required in order to achieve good quality WPC
recyclate.
the proportion of WPC-PVC in the „refinate“ produced was
reduced from 56% at the beginning to approx. 2%.

As part of the investigations into the recycling of WPC, resear-
chers also investigated whether WPC particles can be auto-
matically sorted into various plastics types in various fractions.
In recycling technology, it is often important to sort materials
containing PVC out from the recyclate in order to enable recy-
cling of the material or its use as an energy source. One aspect
of the project is therefore the separation of WPC containing
PVC using near-infrared spectroscopy in a sorting plant.
Certain plastics can be removed from a materials stream by
using inline measurement of reflection spectrums in the near-
infrared region (wavelength between approx. 1000 nm and
2500 nm) to recognise them and then to remove them from
the stream using dual-stream pneumatic sorting in a sorting
plant1). In order to do so, WPC profiles with a variety of
plastics recipes were shredded. The respective plastics compo-
nents however were not given any additional pigment so that
the particles appeared „wood coloured“. After sorting twice,
The research undertaken has been able to demonstrate that
under the conditions of the experiment (uncoloured material),
it is possible to reduce the proportion of unwanted WPC-PVC
to around 2% by weight and thus largely to remove this frac-
tion from a materials stream. However, a sorting plant can only
be set up to sort a certain range of grain sizes and a particular
material density. The classification model is therefore only
valid for the material fractions which have been input and the
quality of any near-infrared spectrum sorting depends largely
on the quality of the signals and the ability to classify them
with certainty. Dark pigmentation of the plastics largely gives
a poorer signal-to-noise ratio. Signals with higher spectral and
spatial resolution (e.g. 300 pixels per line) in a broader wave-
length range (e.g. 1200 nm to 2000 nm) can be achieved with
a hyperspectral camera, for example. In order to use them for
improved sorting, however, further investigations and develop-
ment are required.

The project to develop a hardwood timber brochure was
begun in 2014 by the iVTH in conjunction with the NHN. The
objective is to present the opportunities for using hardwoods
and to promote the use of a range of hardwoods against the
background of the „hardwood problem“. The intention is that
the technical compendium will be of interest to companies ac-
tive in the area of hardwood exploitation, associations and in-
terested circles from the timber and forestry industries as well
as universities and research institutions amongst others. The
brochure will provide information about a range of subjects
including the significance for forestry of native hardwoods,
their timber properties and the possibilities for working and
processing them. The treatise will be published in 2015.
A Look Ahead to 2015
Development of a brochure on the use of hardwood timber as a material
A variety of research applications submitted to the Federation
of Industrial Research Associations AiF via the iVTH have now
been examined and approved. The following are some of
those projects:
„Alternative formaldehyde-free urea resins for wood-
based panels and decorative papers“
The research project concerns the measures required to further
reduce and avoid the use of formaldehyde due to the Europe-
an reclassification of the substance. In the joint project by the
Fraunhofer Institutes for Wood Research WKI in Braunschweig
and for Applied Polymer Research IAP in Potsdam, alternative
formaldehyde-free urea resins for wood-based panels and
decorative papers will be developed and tested to practical
maturity over a period of 2 1/2 years. The project follows on
from a very promising forerunner and if successful could con-
tribute significantly to enabling the production of much lower
emission wood-based panels and products made from them at
economically justifiable cost.
„Development of a model-based process simulation for
the manufacture of decorative, three-dimensional for-
med veneered surfaces“
Another project that has been underway since January 2015
is entitled „Development of a model-based process simulation
for the manufacture of decorative, three-dimensional formed
veneered surfaces“. The objective of this project is to increase
the high-quality finishing of wood products with real wood
veneers in the fields of furniture and interior finishing. The
research partners, the Institute for Wood and Paper Techno-
logy of the Technical University Dresden and the Engineering
Faculty of the University of Schmalkalden, are able to base
their work on the findings of a previous project.
„Vibroacoustics in the planning process for wooden buil-
dings – modelling, digital simulation, validation (II)“
The CLUSTER project „Vibroacoustics“, organised as three
project parts, was started in 2012 and extended in 2015.
The planning of a timber construction building is a significantly
greater challenge than a conventional building. This is in part
due to the lack of proven constructions and construction tools
for sound insulation and performance. Suitable computer-ba-
Research projects in 2015
sed planning tools, which make it possible to create a simula-
tion for the entire building in the early planning stage, could
drastically reduce the time and effort required for planning.
The planning tools to be developed as part of the project will
enable a planning process which is more efficient and there-
fore better value.
Rosenheim University of Applied Sciences is responsible for
managing part 3 of the project: Developing parameters and
SEA modelling (Statistical Energy Analysis).
ift Rosenheim is responsible for managing part 4 of the
project: Vibroacoustics in the planning process for timber
buildings. The objective of the research is to develop an FEM-
based calculation model for air and impact noise insulation in
construction situations and a construction component databa-
se for solid wood elements.
The Chair of Structural Mechanics at the Technical Universi-
ty Munich is responsible for Part 5 of the project: Frequency
range-dependent modelling for predicting structure-borne
sound propagation in timber buildings. In this part of the
project, researchers hope to develop possibilities for predic-
ting structure-borne sound transmission considering adjacent
construction components, especially where wall and ceiling
components meet in timber buildings. Depending on the fre-
quency range, a variety of prognosis processes will be used for
dynamic analysis.
