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.

Method for producing a molded part from a carbon material using recycled carbon fibers and molded part

A heating device is formed from an electrically conducting, flexible resistance material of carbon fibers arranged between at least two electrodes provided for electrical contacting. The carbon fibers are stretch-broken carbon fiber yarns with a titer of 30 tex to 800 tex and a resistivity of 100 to 600 &#x3a9;/m.

Stretch-broken carbon fiber yarns for a heating device

A process for producing a friction material based on a sheet-like carbon fiber woven fabric for wet-friction elements, such as clutch linings or synchronizing ring linings. The woven fabric of carbon fibers is impregnated with a binder, in particular with a resin, to form a binder-impregnated fiber material. The prepreg is cured for a curing period under a curing temperature which is elevated with respect to the ambient temperature and is pressed mechanically on its surfaces with a pressing mold before the start and/or at least during part of the curing period.
