Abstract
A method produces a molded part from carbon containing carbon fibers in an amount of less than 20% by weight. The method includes comminuting waste parts or scrap parts formed from a carbon fiber-reinforced synthetic material, a carbon fiber reinforced carbon or a carbon fiber reinforced concrete. A mixture is produced from the comminuted product, a binder such as pitch, a carbon material such as coke and optionally one or more additives, wherein the mixture contains less than 20% by weight of fibers. The mixture is molded into a molded part and the molded part is carbonized. Optionally, the molded carbonized part is impregnated with an impregnating agent. Finally and optionally, the molded carbonized part or the molded part impregnated part is graphitized.
