How is it made? The raw material used to make carbon fiber is called the precursor. About 90% of the carbon fibers produced are made from polyacrylonitrile (PAN). The remaining 10% are made from rayon or petroleum pitch. All of these materials are organic polymers, characterized by long strings of molecules bound together by carbon atoms.
Synthetic fibers come from manmade processes and chemicals. Fibers such as polyester and nylon are made of chemical polymers spun into threads. However, some synthetic fibers come from natural sources. For example, modal and rayon come from wood cellulose that uses chemical processes to convert wood into fiber. Learn more about Sewing
