摘要
在先驱体法制备碳化硅 (Si C)纤维的过程中 ,聚碳硅烷 (PCS)纤维的不熔化反应程度对终烧 Si C纤维的性能具有重要影响。本文就 PCS纤维的不熔化反应程度的表征方法进行了探讨。结果表明 ,PCS纤维不熔化反应程度可以用 PCS纤维的硅 -氢 (Si— H)
The curing reaction degree of polycarbosilane(PCS) is one of the important factors on the properties of the silicon carbide(SiC) fibers during the preparation course of SiC fibers.In the paper,an IR method for the characterization of curing reaction degree of PCS fibers were analyzed.The curing reaction degree of PCS fibers can be characterized via Si-H bond measure ment.
