High-strength carbon fiber enhanced silicon dioxide ceramic matrix composite and preparation method thereof
The invention discloses high-strength carbon fiber enhanced silicon dioxide ceramic matrix composite and a preparation method thereof. The high-strength carbon fiber enhanced silicon dioxide ceramic matrix composite is characterized by being prepared from raw materials in parts by weight as follows: 20-40 parts of aluminum oxide, 30-50 parts of silicon dioxide, 10-13 parts of modified high-elastic carbon fiber, 5-7 parts of acrylamide, 0.02-0.05 parts of tert-butyl hydroperoxide, 0.3-0.6 parts of p-toluenesulfonic acid, 1-2 parts of boric acid, 3-5 parts of diatomaceous earth, 2-3 parts of starch, 1-2 parts of polyacrylic acid, 20-30 parts of ethanol and 30-50 parts of deionized water. With 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; added aluminum oxide can improve compactness and hardness; added boric acid generates melt boric oxide at the high temperature and can reduce the temperature for sintering, resource losses can be reduced, and social benefits are increased.
