The carbon fiber is used as the reinforcement and the carbon is the matrix, which is made of all-carbon composite material through impregnation, hot pressing, carbonization, CVD densification and other treatments. It has the advantages of low density, high strength, high thermal conductivity, low expansion coefficient, good friction performance, good thermal shock resistance and high dimensional stability. It is widely used in single crystal furnace insulation, hot field loading, C/C composite brake discs, etc.
The carbon/carbon composite material (carbon/ceramic composite material) processed by coating treatment or high temperature infiltration ceramization has excellent oxidation resistance and high temperature ablation resistance, the only feasible protection scheme under ultra-high temperature conditions , Widely used in the aerospace industry.
