新型耐高温氮化物陶瓷纤维研究进展

摘要

介绍了耐高温氮化物陶瓷纤维的种类及制备方法即有机聚合物先驱体转化法；综述了Si3N4,BN,SiBN,SiBN(C)陶瓷纤维的研究进展；重点介绍了SiBN(C)陶瓷纤维的研究现状,并与SiC纤维进行性能对比.指出具有耐高温、透波性等功能结构一体化的SiBN(C)陶瓷纤维是陶瓷纤维的重要发展方向,简化先驱体的合成过程及降低制备成本是技术关键,聚合物分子结构设计和纺丝工艺还有待深入研究.%Hie variety and the production technology, I.e. Organic polymer precursor conversion method, of high temperature resistant nitride ceramic fiber was introduced. The research progress in Si3N4, BN, SiBN and SiBN(C) ceramic fibers was reviewed. The research situation of SiBN(C) ceramic fiber was emphatically introduced. And the properties of SiBN( C) ceramic fiber were compared with those of SiC fiber. It was pointed out that the development trend of ceramic fibers would focus on the function-structure integrated SiBN(C) ceramic fiber with high temperature resistance and wave transmissivity, the key technology should be the simplification of precursor synthesis process and the reduction of production cost, and the polymer molecular structure design and the spinning process should be studied further.
