...). Carbon fibers are used in epoxy-bonded composites. Although soot and coal often are referred to as being amorphous, they actually contain small regions that are graphitic or diamond-like. Amorphous carbon can be produced by vapor sputter deposition. Some of the bonding is sp 2 (graphite-like...
