系统分析研究了影响晶须补强增韧Si_3N_4陶瓷基复合材料的韧性和强度的主要因素,提出复合材料界面设计和复合工艺的新构思,并实现了SiC晶须对Si_3N_4陶瓷的增韧补强双重效果,制备了高性能SiC晶须补强增韧Si_3N_4陶瓷基复合材料。
The main factors influencing the toughness and strength of whisker reinforced toughening Si_3N_4 ceramic matrix composites were systematically investigated. A new concept of composite interface design and composite process was proposed, and toughening and strengthening of Si_3N_4 ceramics by SiC whiskers Double effect, prepared high-performance SiC whisker reinforced toughening Si_3N_4 ceramic matrix composites.
