High-strength carbon fiber enhanced zirconium boride ceramic matrix composite and preparation method thereof
The invention discloses high-strength carbon fiber enhanced zirconium boride ceramic matrix composite and a preparation method thereof. The high-strength carbon fiber enhanced zirconium boride ceramic matrix composite is characterized by being prepared from raw materials in parts by weight as follows: 20-30 parts of silicon barium aluminum, 50-70 parts of zirconium boride, 10-14 parts of modified high-elastic carbon fiber, 4-6 parts of copper powder, 8-12 parts of cordierite, 5-8 parts of acrylonitrile, 0.03-0.05 parts of dibenzoyl peroxide, 0.3-0.6 parts of 3- amino propyl trimethoxy silane, 10-13 parts of talcum powder, 1-3 parts of sodium dimetaphosphate, 2-3 parts of starch, 20-25 parts of ethanol and 50-60 parts of deionized water. With modified high-strength carbon fiber as an enhancing phase, the high-strength carbon fiber enhanced zirconium boride ceramic matrix composite has the advantages of excellent oxidation resistance, improvement of ceramic toughness and strength, high-temperature and low-temperature resistance, good thermal conductivity and small expansion coefficient; the added copper powder forms a three-dimensional network structure with ceramic in the sintering process, so that ceramic has high strength, high toughness and high rigidity characteristics, and a metal toughness enhancing function is realized.
