The reaction expels hydrogen gas and a ribbon-like ring polymer is formed.  This time, it is heated once again from 600 degrees to a hot 1300 degrees Celsius.  This is cause the ribbons to join themselves together to even wider ribbons. When this happens, we expel nitrogen gas. As you can see on the polymer we get, it has nitrogen atoms along its edges, and these new wide ribbons can then merge to form even wider ribbons. As this happens, more and more nitrogen is expelled. When we're through, the ribbons are really wide, and most of the nitrogen is gone, leaving us with ribbons that are almost pure carbon in the graphite form. That's why we call these things carbon fibers.

Even the Jordan's steering wheel is made from carbon fiber! A typical steering wheel alone of a Formula One car costs about $9500.  It contains almost everything the driver needs (except for the two pedals, of course). The unpainted wing of the Jordan Mugen-Honda. The carbon fiber 'weaves' are clearly seen here. The Hornet symbol has been adapted from Jordan's 1998 season.
