Abstract
Process for producing shaped bodies comprising fiber-reinforced ceramic materials, where a green body is produced in a first step by introducing a press moulding composition into a mold, where the press moulding composition comprises carbon fibers and/or carbon filaments and pitch and/or resins which, when treated thermally and with the exclusion of oxidizing agents, form carbon-containing residues, the green body is cured in a second step by heating to a temperature of from 120° C. to 280° C. under pressure, the cured green body, also referred to as intermediate body, is carbonized in a third step by heating in a nonoxidizing atmosphere to a temperature of from about 750° C. to about 1100° C. to form a C/C body, wherein heating in the first, second and/or third step is at least partly effected by an electric current being passed through the pressable composition, the green body and/or the cured green body, shaped bodies produced according to this process and their use as brake disks, clutch disks and friction disks
