航空航天领域的炭/炭密封材料研究进展

Research Development of Carbon/Carbon Sealing Material In Avigation and Spaceflight Field

将炭/炭(C/C)复合材料与石墨材料的性能进行对比分析,指出C/C复合材料是未来航空航天领域中很有前途的一种摩擦密封材料。对近年来国内外C/C复合材料的不透性、力学性能、摩擦磨损性能研究进展进行了概述,介绍了C/C密封材料制备工艺;分析了当前研究中存在的问题,提出了相关建议。

The performance contrast between graphite and C/C composite material is analyzed, the results show that the C/C composite is a promising friction and sealing material in aviation and spaceflight field. New research de velopment on impermeable, mechanical, friction and wear properties of C/C composite material both at home and abroad is reviewed, the manufacture technology is also introduced; then relevant proposals for the current problems are put forward.
