Abstract
The invention relates to a method for producing ceramic brake discs, comprising the following steps: a) producing a BMC compound (2) with a matrix consisting of phenol resin and with carbon reinforcement fibres, the length of the carbon fibres being between 6 mm and 50 mm; b) poducing a green compact of the ceramic brake discs from the BMC compound (2) in a transfer moulding or injection compression moulding process, c) pyrolysing the green compact in order to produce a porous moulded body; and d) melt-infiltrating the porous moulded body with a melt, preferably a silicon melt, in order to produce a moulded body with reaction-bonded fibers.
