摘要：
The C/C-SiC composites as a new generation of the high-temperature resistant ceramic matrix composite material has delivered improved performance in several applications such as thermal structure and thermal protection systems, advanced friction systems and space optical systems, because of its high specific strength, high mo-dulus, low thermal expansion coefficient and high-temperature oxidation resistance. However, the oxidation and ablation resistance of C/C-SiC composites need to be improved to satisfy the demands for the new generation of hypersonic vehicles and reusable space transportation vehicles operated in the extreme environment with high heat flux, high pressure airflow and high speed erosion of particles. For C/C-SiC composites, research mainly focus on three methods including coating modification of carbon fibers, matrix modification and high-temperature protective surface coating. According to both internal and external research reports in recent years, new progresses in high-temperature protection of C/C-SiC composites are described in detail. Preparation methods of coating modification of carbon fibers, matrix modification and high-temperature protective surface coating are concluded, while the characteristics of three high-temperature resistance methods are compared. Finally, several opinions of trends in development of high-temperature protection of C/C-SiC composites are put forward. © 2016, Materials Review Magazine. All right reserved.
