Abstract

A process for producing hollow bodies comprising fiber-reinforced ceramic materials, in which a green body comprising compressible cores and a mouldable composition comprising binders and fiber material which is pressed with compression of the core is produced, the green body is cured and carbonized and pyrolysed by heating in a nonoxidizing atmosphere and, if desired, the body is silicized, hollow bodies produced in this way and their use, in particular as brake and clutch disks
