摘要
为制备耐高温性能良好的SiC纤维,必须降低纤维中的氧含量,本文详细综述了国内外先驱体转化法制备SiC纤维中降低氧含量的方法,分析了各种方法的优缺点,比较可行有效的方法有电子束/γ射线辐射交联法、高温脱氧法和低度预氧化+热交联法,为制备高性能SiC纤维提供了一些参考。
In order to promote the mechanical properties of SiC fibers at high temperatures, oxygen content must be decreased. In this paper, the main methods of making low oxygen content SiC fibers is presented,and their advantages and limitations are analyzied. Electron beam or γ irradiation curing, eliminating oxygen at high temperature and low-oxidation + thermal-curing are feasible and effective methods. It will provide a reference for making high performance SiC fibers.
