金属基复合材料由于具有工作温度高、层间剪切强度高、导电、导热、耐磨损、不吸湿不放气、尺寸稳定、不老化等一系列优异性能,受到极大重视,是近年来材料研究的重要领域。长期以来,用亚显微强化相分散在基体中弥散强化的复合材料、用高颗粒状物质赋予强化效果的颗粒增强金属基复合材料以及利用纤维做增强体的纤维增强金属基复合材料虽有很大发展,然而由于金属基复合材料工艺复杂,成本高,它的发展规模一直落后于树脂基复合材料。目前制造廉价、耐热性好、增强效果明显的增强颗粒、纤维
Due to its high working temperature, high interlaminar shear strength, conductive, thermal conductivity, wear resistance, non-hygroscopic non-deflation, dimensional stability and aging resistance, metal matrix composites have received great attention in recent years Material research in important areas. For a long time, the use of sub-microstructurally dispersed dispersed in the matrix dispersion strengthened composites, with a high particulate matter to give the strengthening effect of particle reinforced metal matrix composites and fiber reinforcements using fiber reinforced metal matrix composites Although there are However, due to the complexity and high cost of metal-matrix composites, its development scale has lagged behind that of resin-based composites. At present, the manufacture of low-cost, heat resistance, and enhance the obvious enhancement of particles, fibers
