Carbon Fiber

• Also called graphite fiber.
• It is in the form of several long strands of a
  material mainly composed by carbon atoms.
• Each strand is 0.005 0.010 mm thick in
  diameter.
• First made by Dr.
• Roger Bacon.

3
Advantages

• It has the greatest compressive strength of all
  reinforcing materials.
• High strength to weight ratio.
• Low coefficient of thermal
• expansion.
• Its density is much lower
• than the density of steel.

4
Applications

• 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.

5
Creation

• Spinning A polyacrylonitrile plastic is spun
  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.

Carbon Fibers Future

• Alternate Energy wind turbines, compressed
  natural gas storage and transportation fuel
  cells.
• Fuel Efficient Automobiles moving towards large
  production series cars.
• Construction Infrastructure light weight
  pre-cast concrete, earthquake protection.
• Oil Exploration Deep sea drilling platforms,
  buoyancy, umbilical, choke, kill lines and drill
  pipes.
