Patent ID: 7186360

Claim:
A process for producing ceramic composite materials with unidirectionally aligned reinforcing fibers, which comprises: providing a polymer over reinforcing fibers, the polymer having a mass; processing the reinforcing fibers having the polymer thereover by adding binder resins to form a unidirectionally reinforced CFK molded part; carbonizing the unidirectionally reinforced CFK molded part to form a Carbon Fiber-reinforced Carbon (CFC) body; decomposing the polymer at least almost completely during the carbonizing step to form a carbon residue in an amount of up to 60% of the mass of the polymer, to form a pore channel structure, and to set at least one of a volume ratio of the polymer to the reinforcing fibers from 0.05 to 50 and a mass ratio of the polymer to the reinforcing fibers from 0.1 to 25; and infiltrating the CFC body with liquid silicon to penetrate the liquid silicon into the pore channel structure formed in the CFC body and to combine the liquid silicon at least partially with the carbon residue to form silicon carbide.
