Composite Materials: A composite material can be defined as a combination of two or more materials that results in better properties than those of the individual components used alone. The two constituents of a composite are a reinforcement and a matrix.
Matrix: The continuous phase is the matrix, made of polymer, metal, or ceramic.
Reinforcement: A strong, inert, woven and nonwoven fibrous material incorporated into the matrix to improve its mechanical and physical properties. For example, fibers, whiskers, particulate etc.
High Performance Fibers- Aramid fibers- Their Spinning Techniques-Naveed Ahmed Fassana
A brief introduction of High Performance fibers and spinning techniques through which these fibers are produced are mentioned in these slides. Also there is a brief explanation of Aramid, Kevlar, and Nomex fibers with respect to their properties with the help of graphs etc.
Aramid fiber are one of the high thermal high performance(HT-HP) modern fibers that are potentially of interest in civil, defence, automobile industries, and Technical textile fields. Being characterized by high strength, high stiffness, low creep and resistance to corrosion un-like carbon or glass fiber. However the aramid fiber are frequently used with out resin impregnation to resistance of fire.
Eg.- Kevlar, Nomex, Twaron, and Technora are commercial name of aramid fiber.

Carbon fibers in automotive and aircraft applicationsrohannaik42
Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motor sports, along with other competition sports.
FIBER SELECTION
Factors to consider when choosing glass type include thermal properties; fiber cost, type of manufacturing process being used, and forms of reinforcement

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.
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
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.
