Part 8. CARBON FIBRES

  • Carbon in the form of its allotrope graphite is soft, slippery and easily broken solid.

  • However, very thin filaments or strands of graphite-carbon (carbon fibres) are very stiff and strong.

  • Precursor fibres of polyacrylonitrile are carbonised under extreme heat is one method of making carbon fibres.

  • Carbon fibres are useful for reinforcing other materials to make them tougher i.e. strengthening composite materials.

  • Carbon fibres can be incorporated into strong plastics to make an even stronger composite material.

  • Carbon fibre materials are not only strong but very lightweight e.g. compared to strong metal alloys like steel.

  • So carbon fibre composites are used for skateboards, boat hulls and high performance sports equipment like tennis racket frames.

  • However, these high performance materials products don't come cheaply, you may pay 7000 for a mountain bike, made from carbon fibres and titanium, that weighs just 6 kg (quote from BBC News website in 2006).
