Abstract
(DE) Ein Verfahren zur Herstellung eines Formteils aus Carbonfasern in einer Menge von weniger als 20 Gew.-% enthaltendem Kohlenstoff umfasst die nachfolgenden Schritte: a) Zerkleinern von Abfallteilen oder Ausschussteilen aus einem carbonfaserverstärkten Verbundwerkstoff, wobei der carbonfaserverstärkte Verbundwerkstoff bevorzugt ein carbonfaserverstärkter Kunststoff, ein carbonfaserverstärkter Kohlenstoff oder ein carbonfaserverstärkter Beton ist, b) Herstellen einer Mischung aus dem in dem Schritt a) erhaltenen, zerkleinerten Produkt, einem Bindemittel, wie Pech, einem Kohlenstoffmaterial, wie Koks, und ggf. einem oder mehreren Additiven, wobei die Mischung weniger als 20 Gew.-% Fasern enthält, c) Formen der in dem Schritt b) erhaltenen Mischung zu einem Formteil, d) Carbonisieren des in dem Schritt c) erhaltenen Formteils, e) optional Imprägnieren des in dem Schritt d) carbonisierten Formteils mit einem Imprägniermittel und f) optional Graphitieren des in dem Schritt d) carbonisierten Formteils oder des in dem Schritt e) imprägnierten Formteils.
(EN) 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).
