Carbon fibers are industrially produced fibers from carbonaceous raw materials that are converted to graphitic carbon by chemical reactions adapted to the raw material. Typically, 1,000 to 24,000 (Tex) filaments are made into a multifilament yarn (Roving), which is wound up.
As short-cut fibers, they can be mixed with polymers and processed into plastic components via extruders and injection molding machines. Carbon fibers are mainly used for the production of carbon fiber reinforced plastic (CFRP = C-fiber reinforced plastic).
