(Third generation) silicon carbide special ceramic fiber has the following characteristics:
1: The Si/C element ratio is close to the stoichiometric ratio, and the crystal structure is close to the ideal diamond structure;
2: High strength and high modulus, high temperature resistance, oxidation resistance, high temperature creep resistance and Irradiation can be combined with ceramic-based, metal-based and resin-based materials to prepare various high-performance composite materials;
3: The density is small, only 1/4 of refractory metals, which can achieve enhanced weight reduction;
4: It can be used in aerobic conditions It can work stably for a long time under the environment of 1450°C, and the instantaneous operating temperature is nearly 3000°C. It is an ideal material for high-temperature structural parts under high-temperature working conditions in the fields of aviation, aerospace, and nuclear energy.
