Carbon fiber composites combine twisted carbon fibers with a resin to produce a material up to four times stronger than steel for its weight. Two main forms exist. The carbon fiber is either chopped into short lengths and attached to the resin backing at random (1) or laid down in strips (2). The former has strength in all directions but the latter has great strength against the grain in different directions to give overall strength in all directions (3). Strands of twisted carbon (4) pass through a chopper (5) and fall onto a backing material (6) coated with the bonding resin (7). Another layer of resin and backing material is then laid on top and the composite is rolled for storage (8).
