Carbon Fiber Production

3.5.2 Carbon Fibers. The raw material used to make carbon fibers is a precursor represented by polyacrylonitrile (PAN, nearly 90% of the carbon fiber's production), whereas the remaining 10% are made from rayon or petroleum pitch. An example of carbon fiber production from PAN is shown in Figs. 3.41 and 3.42.
