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 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
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).
