摘要
A method for the production of ceramic composite materials with a unidirectional alignment of the reinforcing fibers, characterized in that– first fiber strands or rovings of the reinforcing fibers and fibers of a victim of polymer are wrapped, wherein the volume ratio of the sacrificial polymers to the fiber strands or rovings of 0,05 to 50 and / or the mass ratio of sacrificial polymers to the fiber strands or rovings of 0,1 to 25, and– the thus processed fiber strands or rovings with the addition of binder resins unidirectionally reinforced cfk - shaped bodies to be processed,– the formed cfk - body to be carbonized to cfc - bodies, wherein the victims of polymer in the carbonization either– completely or– with the formation of a said carbon residue of up to 60% of the mass of the sacrificial polymers decomposed,with a pore channel structure, and– the formed cfc - body is then be infiltrated with liquid silicon in such a way that the liquid silicon into which, in the cfc - body and pores formed there at least partially with..
