超高温材料的研究进展

Research Progress of Ultra-High Temperature Materials

超高温材料对于航天飞行器具有重要作用,是飞行器在长时飞行、跨大气层或再入飞行中不可或缺的组成部分,对飞行器的热防护系统起着至关重要的作用。本文对近年来难熔金属及其合金、C/C复合材料、超高温陶瓷等超高温材料的最新研究成果进行归纳、总结,分析超高温材料的优缺点,提出存在的主要问题,探讨今后的主要研究目标和重点发展方向。

The ultra-high temperature materials(UHTM) are the essential materials, which used for air vehicle covering form the long-time flight, reentry flight and break out the atmosphere. Such materials played an important role in the researching process of the flight and were critical for the thermal protection system. In this paper, the forces on the achievements of previous work in such material, including carbon/carbon composites, ceramic-based composites, carbide UHTM, and boride UHTM. The unsolved problems in those material were also discussed.The potential development direction of the UHTM were given at last.
