METHOD FOR PRODUCING A MOLDED PART FROM A CARBON MATERIAL USING RECYCLED CARBON FIBERS

摘要

The invention relates to a method for producing a molded part from carbon fibers in a quantity containing less than 20% by weight carbon comprises the following steps: a) comminuting waste parts or scrap parts from a carbon fiber-reinforced composite material, wherein the carbon fiber-reinforced composite material is preferably a carbon fiber-reinforced synthetic material, a carbon fiber-reinforced carbon or a carbon-reinforced concrete, b) producing a mixture of the comminuted product obtained in step a), 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 fibers, c) molding the mixture obtained in step b) to form a molded part, d) carbonizing the molded part obtained in step c), e) optionally impregnating the carbonized molded part obtained in step d) with an impregnating agent, and f) optionally graphitizing the molded part carbonized in step d) or the molded part impregnated in step e).
