陶瓷基复合材料(CMC)是在陶瓷中引入第二相材料,使之增强,增韧的多相材料.法、美、德、日等发达国家20多年来积极开展研究,目前陶瓷基复合材料已在航空航天发动机、航天热防护系统、原子能等领域已经得到应用。 Ceramic matrix composites (CMCs) are multiphase materials that have been introduced into ceramics to enhance and toughen the second phase materials. Developed countries like France, the United States, Germany, Japan and other developed countries have been actively conducting research for more than 20 years. At present, ceramic matrix composites Has been applied in aerospace engines, aerospace thermal protection systems, atomic energy and other fields.
