Abstract
A method for preparing a ceramic-modified carbon-carbon composite material. The method includes preparing and thermally treating a carbon fiber preform, and depositing pyrolytic carbon on the carbon fiber preform in a chemical vapor infiltration furnace, to yield a porous carbon-carbon composite material; placing the carbon-carbon composite material deposited with the pyrolytic carbon on a zirconium-titanium powder mixture, and performing a reactive melt infiltration, to yield a carbon-carbon composite material modified by non-stoichiometric zirconium titanium carbide; and placing the carbon-carbon composite material modified by non-stoichiometric zirconium titanium carbide in a powder mixture including carbon, boron carbide, silicon carbide, silicon, and an infiltration enhancer, and performing an embedding method, to form a ceramic-modified carbon-carbon composite material.
