1, high temperature resistance: the matrix of ceramic matrix composites is mostly ceramic materials with high melting point, so it can maintain excellent stability and strength in high temperature environment. In addition, the reinforced phase introduced into ceramic matrix composites can also improve the high temperature resistance of the materials.

2. Corrosion resistance: Ceramic matrix composites have good corrosion resistance, because their matrix and reinforcing phase have good chemical stability and are not easy to react with chemicals such as acid, alkali and salt, so they can be used in various corrosive environments.
