本文就用添加剂来改善用聚碳硅烷热解制备的SiC/SiC复合材料的性能,及添加剂对SiC/SiC复合材料性能的影响进行了初步的探讨,对用热解法制备SiC/SiC复合材料的烧成增强机制和显微结构与强度之间的关系也作了研究。
In this paper, additives were used to improve the properties of SiC / SiC composites prepared by pyrolysis of polycarbosilane and the effects of additives on the properties of SiC / SiC composites. The preparation of SiC / SiC composites by pyrolysis The firing enhancement mechanism and the relationship between microstructure and strength have also been studied.
