金属基复合材料在很多空间应用中起着重要作用。特别是，金属基复合材料(MMCs)为通讯卫星提供热控和电子封装材料、用作航天飞机的中舱支架以及哈泊空间望远镜所必须的天线波导管等。MMCs具有高比强度、比刚度、良好的热传导和导电性能以及适度的热胀系数(CTE)。MMCs一般能经受 Metal matrix composites play an important role in many space applications. In particular, metal matrix composites (MMCs) provide thermal and electronic packaging materials for communications satellites and are used as midship supports for space shuttles and antenna waveguides necessary for Haerba space telescopes. MMCs have high specific strength, specific stiffness, good thermal conductivity and electrical conductivity, and moderate thermal expansion coefficient (CTE). MMCs can generally withstand
