2. 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.

3. 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.

4. 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.

5. How is Carbon Fiber Made?
 Production from two sources -:
 Polyacrylonitrile (PAN)
 Pitch
The raw material used to make carbon fiber is called the
precursor.

6. In General Carbon fiber are produced in three
processing stages:
 1. Stabilization
 2. Carbonization
 3. Graphitization

7. 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.

8. 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.

9. DISADVANTAGE
 It is very costly.
 It is little bit harmful for the human body as it cause
some form of cancer of the lungs.

10. APPLICATIONS
 It is mostly used in the aerospace and aircraft industries.

11.  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.

12.  Constructing up of wind mill blades.

13.  It is used for building
and construction
material.
 Rechargeable
batteries and fuel cell
electrodes.
 Portable powers.
• It is also used in civil
engineering

15. Carbon Fiber Markets

16.  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
