纤维增强陶瓷基复合材料界面及增韧机制的进展

Interface of Fiber-Reinforced Ceramic Matrix Composites and the Development of Toughening Mechanism

陶瓷基复合材料以其优异的耐高温、热稳定性好、耐磨损等性能,在高技术领域和航空航天领域有重要应用。界面在纤维和陶瓷基体之间起着决定性的作用,复合材料的界面相是纤维与基体连接的纽带,也是应力及其它信息传递的桥梁。本文分别从不同复合方式、复合材料的界面研究及纤维增强基体的增韧机制和界面的力学性能等方面进行了综述。

Because of the excellent thermal stabilization, wear and tear resistant inherent resistance at high temperatures, ceramics matrix compositions are applicated in high-technique and aerospace field. The composition interface has decisive action between fiber and ceramics matrix, which is a link of fiber and matrix and also is a bridge of stress and other information. This thesis discusses respectively from the aspects of interface research for different fiber-reinforced ceramic matrix composites, and the enhance of mechanical properties between tou^henin~ mechanism and interface.
