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 (5a, 5b), 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.
