2. CARBON FIBER
 The term Carbon Fiber refers to
materials (filaments, yarns, roving)
consisting of at least 92% Carbon.

3. PROPERTIES OF CARBON FIBERS
UNIVERSITY OF AGRICULTURE FAISALABAD – UAF
 High Strength and Stiffness
 Low Density
 Corrosion resistance
 Electrical Conductivity
 Fatigue Resistance
 Fire Resistance/Not flammable
 High Melting Point (Heat Resistant)
 Non poisonous
 Biologically inert
 X-Ray Permeable

PROPERTIES OF CARBON FIBERS
 Carbon Fiber is very Rigid
 Rigidity or stiffness of a material is measured by its Young Modulus and
measures how much a material deflects under stress. Carbon fiber reinforced
plastic is over 4 times stiffer than Glass reinforced plastic, almost 20 times more
than pine, 2.5 times greater than aluminium
 Carbon fiber is Corrosion Resistant and Chemically
Stable
 Although carbon fibers themselves do not deteriorate measurably, Epoxy is
sensitive to sunlight and needs to be protected. Other matrices (whatever the
carbon fiber is embedded in) might also be reactive. Carbon fibres can be
affected by strong oxydizing agents

PROPERTIES OF CARBON FIBERS
 Carbon Fiber has good Tensile Strength
 Tensile strength or ultimate strength, is the maximum stress
that a material can withstand while being stretched or pulled
before necking, or failing
 Fire Resistance/Non Flammable
 Carbon fibre is classified as non conbustible and has no listed flash
point. Depending upon the manufacturing process and the precursor
material, carbon fiber can be be made to feel quite soft to the hand and
can be made into or more often integrated into protective clothing for
firefighting.

PROPERTIES OF CARBON FIBERS
 Non Poisonous, Biologically Inert, X-Ray Permeable
 These quality make Carbon fiber useful in Medical applications. Prosthesis use,
implants and tendon repair, x-ray accessories surgical instruments, are all in
development.
 Although not poisonous, the carbon fibers can be quite irritating and long term
unprotected exposure needs to be limited. The matrix either epoxy or polyester,
can however be toxic and proper care needs to be exercised.

8. USES OF CARBON FIBERS
 Carbon Fiber in Flight
 Carbon fiber has gone to the moon on
spacecraft, but it is also used widely in aircraft
components and structures, where its superior
strength to weight ratio far exceeds that of any
metal. 30 percent of all carbon fiber is used in
the aerospace industry. From helicopters to
gliders, fighter jets to microlights, carbon fiber is
playing its part, increasing range and simplifying
maintenance

9. USES OF CARBON FIBERS
 Sporting Goods
 Its application in sports goods ranges from the
stiffening of running shoes to ice hockey stick,
tennis racquets, and golf clubs.

10. USES OF CARBON FIBERS
 Medical Applications
 Carbon fiber offers several advantages over
other materials in the medical field,
including the fact that it is ‘radiolucent’ –
transparent to X-rays and shows as black
on X-ray images. It is used widely in
imaging equipment structures to support
limbs being X-rayed or treated with
radiation.

11. USES OF CARBON FIBERS
 Automobile Industry
 As costs come down, carbon fiber
is being more widely adopted in
automobiles. Supercar bodies are
built now, but its wider use is likely
to be on internal components
such as instrument housings and
seat frames.

12. USES OF CARBON FIBERS
 Carbon fiber Helmet
 Another important and essential aspect of racing
is the helmet and carbon fiber has transformed
this as well.
 It's obvious and probably doesn't need much
explanation but you need to have a helmet
which is as strong as possible, light in weight,
safe and comfortable, and carbon fiber solves all
of these things better than any other
material.Carbon fiber helmets are undeniably
cool and stylish

13. USES OF CARBON FIBERS
 Carbon Fiber Wallets
 A carbon fiber wallet is far more durable
than a leather one, it's lighter, more
compact.

14. USES OF CARBON FIBERS
 Carbon Fiber Ring
 A black carbon fiber ring is scratch-
resistant, very trendy and quite often
more affordable when compared to
traditional rings made from silver or gold.

15. USES OF CARBON FIBERS
 Bullet Proof
 Due to High stiffness and high strength
carbon fibes are used for bullet proof
purposes

16. USES OF CARBON FIBERS
 Use in Cranes
 Carbon fibers are
used in heavy loads
machinery due to its
superior properties
i.e. less denser, high
strength etc
