3. COMPOSITE MATERIALS

4. 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.

5. 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.

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

7. Precursors

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

9. PAN
• In the stabilization stage, the PAN fibers are first stretched to align the
febrile networks within each fiber axis, and they are oxidized in air at about
200 to 220C while held in tension.
• In carbonization the stabilized PAN-based fibers are pyrolyzed (heated)
until they become transformed into carbon fibers by the elimination of O,H
& N from the precursor fiber.

10. • The carbonization heat treatment is usually carried
out in inert atmosphere in the 1000 to 1500C range.
During the carbonization process, turbostratic
graphite like fibrils or ribbons are formed within each
fiber that greatly increase the tensile strength of the
material.
• In the third stage , or graphitization treatment is
used if an increase in the modulus of the elasticity is
desired at the expense of high tensile strength.
During Graphitization, which is carried out above
about 1800C , the preferred orientation of the
graphite like crystallites within each fiber is
increased.

11. • Carbon fiber are produced from Pitch precursor as well.
• Production of carbon fiber is initiate by process known as polymerization ,
when pitch is heated at 300C, several carbon aromatic rings chain combines
with Each other & generate stable sheet type 2-D structure which is known as
miso-phase of pitch.
• This meso-phase of pitch is now wrapped around spinner while passing
through die the miso-phase will aligned in the filament direction.
Pitch

12. 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.

13. Carbon Fibers vs. Steel
• Up to 75% lighter
• More durable/corrosion-free
• 3 times higher tensile strength
• 2 times higher stiffness
• Higher temperature tolerance

14. APPLICATIONS
Aeronautical Industry
• It is mostly used in the aerospace and aircraft
industries.

15. Automobile Industry
• Automotive body is also made up of the
carbon fiber(Bonnet, bumper, engine cover,
Car Body parts etc.)

16. Sports Industry
• It is used in making sports equipment such as
light weight badminton rackets, golf stick etc.

17. Civil Engineering
• It is also used in civil engineering

18. Medical Field
• Robot for internal operations
• Medical instruments

19. Power Plant Field
• Constructing up of wind mill blades.

20. Other Industry
• It is used for building and construction
material.
• Rechargeable batteries and fuel cell
electrodes.
• Portable powers.

21. Carbon Fiber Markets

22. 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.

23. DISADVANTAGES
• It is very costly.
• It is little bit harmful for the human body as it
cause some form of cancer of the lungs.
