现代科学技术的发展对材料的要求日益提高,使普通的单一材料越来越难以满足需要。复合材料将多种材料的优点集于一身,扬长避短,兼有高强度、高模量和小比重等一系列优点。复合材料这种可设计性有利于最大限度的发挥材料作用,减少材料用量,满足特殊性能要求。目前,金属基复合材 The development of modern science and technology is increasingly demanding on materials, making ordinary single materials more and more difficult to meet the needs. Composite materials will be a combination of the advantages of a variety of materials, Yang avoid weaknesses, both high strength, high modulus and a small proportion of a series of advantages. The designability of composite materials is conducive to maximize the role of materials to reduce the amount of materials to meet the special performance requirements. At present, metal matrix composites
