High-strength carbon fiber enhanced cerium oxide ceramic matrix composite and preparation method thereof
The invention discloses high-strength carbon fiber enhanced cerium oxide ceramic matrix composite and a preparation method thereof. The high-strength carbon fiber enhanced cerium oxide ceramic matrix composite is characterized by being prepared from raw materials in parts by weight as follows: 15-20 parts of hafnium oxide, 50-60 parts of cerium oxide, 10-13 parts of modified high-elastic carbon fiber, 5-8 parts of nickel powder, 5-8 parts of vinyl acetate, 0.03-0.05 parts of methyl ethyl ketone peroxide, 2-3 parts of citric acid, 0.2-0.4 parts of tetraethylortho silicate, 10-12 parts of albite, 2-3 parts of sodium carboxymethylcellulose, 20-30 parts of ethanol and 40-60 parts of deionized water. With the modified high-strength carbon fiber as an enhancing phase, the high-strength carbon fiber enhanced silicon dioxide 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 nickel powder enables ceramic to have high sintering capability at the lower temperature, the sintering temperature is reduced, resources are saved, the production cost is reduced, and the application is good.
