Progress and key problems in research and fabrication of fiber reinforced metal matrix composite

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, interfacial 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.
