COMPOSITE MATERIALS

Composite = Something made up of distinct parts(or

constituents).

A materials system composed of suitably arranged mixture

or combination of two or more micro or macro constituents

with an interface separating them that differ in form and

chemical composition and are essentially insoluble in each

other.

What is Carbon Fiber ? Composed of carbon atoms bonded together to form a

long chain.

A super strong material that's also extremely lightweight.

Five times stronger than steel , Two times stiffer , and

about Two-Third times less in weight.

Carbon Fiber Thin strands of carbon- even thinner than human hair.

Strands can be twisted together, like yarn- can be woven

together, like cloth extremely lightweight.

How is Carbon Fiber Made? Production from two sources -:

Polyacrylonitrile (PAN)

Pitch

The raw material used to make carbon fiber is called theprecursor.

In General Carbon fiber are produced in three processing stages:

1. Stabilization

2. Carbonization

3. Graphitization

Properties

Carbon fiber has very high tensile strength.

It has low thermal expansion.

It is a light weight material having low density.

It is a good conductor of electricity.

It can wear a high resistance.

ADVANTAGES It has long working life.

It’s density is less than density of steel.

It is insensitive to change in temperature.

It’s properties is much better than any of the other metals.

It’s compressive strength is greater than all the reinforcing

material.

DISADVANTAGE It is very costly.

It is little bit harmful for the human body as it cause

some form of cancer of the lungs.

APPLICATIONS

It is mostly used in the aerospace and aircraft industries.

It is used in making

sports equipment such

as light weight

badminton rackets, golf

stick etc.

• Automotive body

is also made up

of the carbon

fiber.

Constructing up of wind mill blades.

It is used for building

and construction

material.

Rechargeable

batteries and fuel cell

electrodes.

Portable powers.

• It is also used in civil engineering

Carbon Fiber Markets

Carbon Fiber Markets

May 9th 2010, Former President Dr A.P.J Abdul Kalam on

Sunday inaugurated the country's first carbon fiber

manufacturing facility. The Rs 250-crore set up will produce

lightweight material for use in defense, aerospace and

infrastructure — under technology transfer from the Council of

Scientific and Industrial Research's (CSIR) National Aerospace

Laboratory (NAL), which had developed the ultra-light material

for the Light Combat Aircraft.

First carbon fiber plant in India
