综述了碳纤维复合材料的应用现状和发展前景。首先，概述了碳纤维的分类和力学性能以及碳纤维复合材料的特性；重点介绍了碳纤维复合材料在国内外航天领域，特别是在卫星结构、运载火箭、精密支撑构件以及空间镜体等方面的应用情况。指出了目前碳纤维复合材料的主要问题是湿热效应。最后，结合我国国情，对碳纤维复合材料需要解决的问题提出了一些建设性的措施。

Applications and development of Carbon Fiber Composites(CFRPs) are overviewed in this paper. Firstly, the classification and mechanical properties of carbon fibers are described, and the characteristics of CFRPs are discussed. Then，the applications of CFRPs to cosmonautic fields at home and abroad are introduced， especially in satellite structures， carrier rockets, precision components and space mirrors. By taking some experiments for examples, it points out that the hydrothermal effect is main problem for CFRPs. Finally，some constructive ideas are put forward based on national conditions in the course of CFRP development.
