The invention relates to a method for producing ceramic brake disks from a green body consisting of a sheet molding compound (SMC) having reinforcing fibers, and the ensuing pyrolysis and melt infiltration. The aim of the invention is to create a single-element green body comprising very complex inner cavities after pyrolysis. In order to achieve this, the method comprises the following steps: the green body ( 1 ) is produced from a sandwich consisting of SMC ( 2 ), a thermoplastic insert ( 4 ), and SMC ( 2 ) in one working step in a tool ( 5 a , 5 b), subjected to pressure and temperature; and the insert ( 4 ) fills the green body ( 1 ) over its entire surface and comprises openings ( 6 ) which are arranged in such a way that the upper and lower SMC layers ( 2 ) are interconnected, at least in parts.
