CARBON FIBER

INTRODUCTION: Also Called graphite fiber. It is in the form of several long strands of a materils mainly composed by carobn atoms.

Each strand is 0.005-0.010mm thick in diameter. First made by Dr. Roger Bacon. Its density if much lower than the density of steel.

CARBON FIBER

PHYSICAL PROPERTIES High Strength to weight ratio Rigidity Corrosion resistance Electrical Conductivity Fatigue Resistance Good tensile strength but Brittle

Fire Resistance/Not flammable High Thermal Conductivity in some forms

• Low coefficient of thermal expansion

• Non poisonous• Biologically inert• X-Ray Permeable• Self Lubricating• Excellent EMI

(Electromagnetic Interference) Shielding Property

• Relatively Expensive• Requires specialized

experience and equipment to use.

CARBON FIBER

ADVANTAGES: It has the greatest compressive strength of all reinforcing materils. High strength to weight ratio. Low coefficient of thermal expansion. Its density if much lower than the density of steel.

CARBON FIBER

APPLICATION: Used to reinforce composite materials. Used structurally in high-temperature applications. As an electrode with high surface area and impeccable corrosion resistance.

Anti-static component.

CARBON FIBER

APPLICATION:

CARBON FIBER

MANUFACTURING: Spinning: A polyacylonittile plastic is spun into into fibers which are then washed and stretched to the desired diameter.

Stabilizing: Fibers are heated with O2 to make their bonding more thermally stable.

Carbonizing: Fibers then are heated without oxygen, they lose non-carbon atoms and bonded carbon crystals are made.

Treating Surface: The surface is slightly oxidized Sizing: fibers are coated and wounded into bobbins.
