TECHNICAL NOTES

PULTRUSION OF PHKNOLICS

PERA in the UK is to undertake a development programme to assess the potentials for pultruding fibre reinforced phenolics in terms of material interaction, process conditions, and quality of' pro- duct. PERA sees the production of high temperature and f'ire re- sistant phenolic composite profiles and sections as the next ma- jor challenge in the world of composites.

The proposed development programme will take an in-depth look at the following areas: resin system chemistry; curing methods; die design and construction; operating efficiency; mechanical proper- ties, and economics. PERA has the capacity to invite 10 indust- rial companies to participate in this work on a shared cost basis. The project, it is estimated, will cost f150,OOO.

AQUEOUS RELEASE AGENTS FOR TI-IE PROCESSING OF FOLYURRIWANE SYSTEMS

Increased environmental awareness not only by the general public but also bytheauthorities and in industry has led to responsible manufacturers and processors in all industries caring increas- ingly about the products processed or made by them. They have been doing so particularly with regard to how these products af‘f'- ect the environment in general. A relevant example can be seen in polyurethane processing where aqueous release agents are now available as an alternative to solvent-based products. Given appropriately modified methods, theaqueous systems can be used in almost every sector of PU processing.
