    摘要: 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

    摘要: Process for producing bodies from ceramic materials using silicon carbide, comprising the steps: configuration of fiber-reinforced porous bodies (1, 5) that consist of carbon on a base (2) that is inert relative to liquid silicon, the bodies having cavities (3) that are accessible from the exterior or surface recesses (3′), and the cavities (3) being closed at the bottom in the porous bodies or the surface recesses (3′) together with the base (2) forming a reservoir that is sealed at the bottom; heating the configuration by introduction of energy to melt the silicon (6) that is present in the reservoir; and infiltrating the melted silicon in the bodies (1, 5) and reaction of the silicon with the carbon to form silicon carbide; and use of the thus produced bodies as brake disks and as clutch driving disks.
