Carbon fiber is a strong yet lightweight material made by processing precursor fibers through stabilization, carbonization, and sometimes graphitization stages. There are two main precursors used: polyacrylonitrile (PAN) and pitch. PAN precursor involves oxidation and pyrolysis heating steps, while pitch precursor involves polymerization, stabilization in oxygen, and carbonization in inert gas. Carbon fiber has very high tensile strength, low density, and good electrical conductivity. Its major applications are in aerospace and aircraft industries, automotive bodies, sports equipment, civil engineering, and wind turbine blades due to its advantages of light weight, high strength, and temperature insensitivity. India's first carbon fiber manufacturing plant was inaugurated in 2010.

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.
it contain some primary information about carbon black and its manufacturing process... not in detail but just overview...
hope you will find it helpful...
Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to fiberglass , having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber.

THERMAL CONDUCTIVITY ANALYSIS IN VARIOUS MATERIALS USING COMPOSITE WALL APPAR...IAEME Publication
Heat transfer due to temperature difference and mass concentration difference as heat and mass transfer. So many research has been made in past on heat transfer through composite wall of different materials. Which I have extended this work by taking a new materials like a charcoal and natural gum as an composite material along with mild steel, Bakelite and wood. In which I conduct a experiment on a composite material wall apparatus and fitted mica heater plate centrally in the combination on the composite wall and varying the voltage at 80 , 120 ,160 and current is different so I found the thermal conductivity of the material as followed Bakelite – 0.976645 W/m-k , wood- 1.804670 W/m-k , charcoal- 0.272975 W/m-k, and natural gum – 0 according to the found result i hope the natural gum can be used as a insulating material in the future.

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.
7. In General Carbon fiber are produced in three
processing stages:
1. Stabilization
2. Carbonization
3. Graphitization
8. 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.
9. 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.
10. Pitch
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 misophase of pitch.
This mesophase of pitch is now wrapped around
spinner while passing through die the misophase will
aligned in the filament direction.
11. Filaments are cooled to freeze the molecular
orientation again to stabilize the chain of the
polymerized structure, it is heated in a range of
200C-400C. In an oxygen containing environment to
stabilize the structure as well as to make them
infeasible structure .
In the next step the filaments are carbonized at the
temp of 1000C in the presence of inert gas.
Carbonization remove all the O,H & N atoms from
the molecule of the pitch. Hence contained arranged
atom only.
12. After carbonization if it is required to incraese
mechanical property of this carbon fiber it can be
again heat treated by process known as
Graphitization.
In Graphatization , it is heating carbonized carbomn
fiber in the range of 200C or above in the vaccume.
After graphitizaion the mechanical strenth capability
is at maximum level which is a PAN carbon fiber can
sustain.
13. 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.
14. 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.
15. DISADVANTAGE
It is very costly.
It is little bit harmful for the human body as it cause
some form of cancer of the lungs.
25. India gets first carbon fiber plant
May 9th 2010, Former President Dr A P J Abdul
Kalam on Sunday inaugurated the country's first
carbon fibre manufacturing facility. The Rs 250crore set up will produce lightweight material for use
in defence, aerospace and infrastructure — under
technology transfer from the Council of Scientific
and Industrial Research's (CSIR) National Aerospace
Laboratory (NAL), which had developed the ultralight material for the Light Combat Aircraft.
