Types and aerospace applications of the fiber reinforced metal matrix composites were introduced firstly, and then the key problems in research and application of fiber reinforced metal matrix composites were analyzed. Based on the above discussion, the research methods and cores of the key problems were put forward. The interface between fiber and metal matrix is one of the main problems , and the weakness of interface is researched from the surface modification of fibers, interfacial wettability and compatibility, inter-facial reaction and strength, and so on. The research of damage mechanisms of composites should be enhanced, and the estimate system of damage will be instituted to instruct the applications. In addition, advanced forming processes and welding technologies are the important issues to decrease the cost and improve the quality of the composites.%介绍连续纤维增强金属基复合材料的种类及其在航空航天领域的应用情况,并对连续纤维增强金属基复合材料研制过程中的难点和热点问题进行归纳和总结,对关键技术问题提出相应的研究方法和思路.纤维与金属基体间的界面问题是其研究与应用的最主要问题,可以从纤维的表面改性、纤维与基体的相容性和润湿性、界面反应、界面强度等方面入手,结合各种复合材料制备工艺的特点,解决界面薄弱性问题；另外加强复合材料损伤机理的研究,建立其损伤评价体系,可以为其实际应用提供参考依据；先进的加工成型和连接技术,可以降低复合材料零件的制造成本,确保零件质量,是复合材料产业化应用的重要保证.
