摘要
聚碳硅烷和沥青分别是转化ＳｉＣ纤维和碳纤维的先驱体。两者共混和共聚就可以得到一种新功能纤维——ＳｉＣ－Ｃ纤维的先驱体，该先驱体的可纺丝性直接与聚碳硅烷和沥青的性质相关。本文从流变性能与可纺丝性的相关性研究了聚碳硅烷——沥青共混体熔体纺丝条件，对于制备ＳｉＣ—Ｃ纤维时，选择组分材料和共混工艺有指导意义。
Abstract:Polycarbosilane and pitch are the precursors of SiC fiber and carbon fiber separately. A precursor of a new type of SiC-C fiber can be obtained by mixed and copolymerized of polycarbosilane and pitch. The spinningable of The precursor is related to the properties of polycarbosilane and pitch. The spinning conditions of pc-p flux mixture were stuided according to the relativity of rheological behavior and spinningable. They win have the guiding significant for selecting components and mixed process in the produced SiC-C fiber.
