金属基复合材料(MMCs)尚未达到大规模工业应用阶段,但鉴于它在战略上的重要性,近年来在航空航天部门的应用开发进展很快,已接近工业应用。本文以MMCs在航空航天工业中的应用为主线,简单地介绍了MMCs的复合体系和性质、生产方法,着重叙述了铝基、镁基、铜基、钛基、金属间化合物基、难熔金属基等复合材料的应用开发现状,最后指出缺少置信度高的机械性能数据库,缺少能实现工业规模生产的工艺方法,特别是增强剂的价格还很高,限制了MMCs的应用开发。尽管如此,铜基和镁基复合材料仍将以年平均增长20％的速度发展,但铝基复合材料在销售量上仍将占主导地位。
Metal-matrix composites (MMCs) have not yet reached the stage of large-scale industrial applications, but in view of their strategic importance, applications and developments in the aerospace sector have progressed rapidly in recent years and are approaching industrial applications. In this paper, MMCs in the aerospace industry as the main line, simply introduced MMCs composite system and nature, production methods, focuses on the aluminum, magnesium, copper, titanium, intermetallic compound, refractory metals Based composites. Finally, the lack of a database of mechanical properties with high confidence level is lacking, and the process method for industrial scale production is lacking. In particular, the price of enhancers is still very high, which limits the application and development of MMCs. Nevertheless, copper-based and magnesium-based composites will continue to grow at an average annual rate of 20%, but aluminum-based composites will continue to dominate sales.
