| titleOfInvention | Preparation method of Cf/SiC composite material with HfB2 interface |
| abstract | The invention discloses a catalyst with HfB 2 The preparation method of the interface Cf/SiC composite material comprises the following steps: activating the surface of carbon fiber, preparing an interface phase, preparing a porous fiber preform, and preparing a silicon carbide substrate; the carbon fiber reinforced silicon carbide ceramic matrix composite is characterized in that a silicon carbide matrix is filled in a fiber preform to form a carbon fiber reinforced silicon carbide ceramic matrix composite, and an interface layer wraps the surface of carbon fibers in the composite. The invention prepares the high temperature resistant and oxidation resistant HfB on the surface of the carbon fiber 2 The interface phase keeps the original mechanical property of the carbon fiber and improves the high-temperature oxidation resistance of the carbon fiber. The invention solves the technical problems that the preparation period of the traditional preparation method of the silicon carbide ceramic matrix composite material is long, the interface compatibility of the toughening phase carbon fiber and the silicon carbide matrix in the Cf/SiC composite material is high, and the carbon fiber is easy to generate oxidation reaction in a high-temperature oxidizing use environment. |
