| 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，两者共混或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，只有两组份的可纺丝温度区间交叉才可能得到可纺性好的聚碳硅烷──沥青共混先驱体。该研究结果对于制备ＳｉＣ－Ｃ纤维时选择组份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.They can be blended into a precursor of a nwe type of SiC-C fiber.The spinningability of this precursor is related to the properties of poly carbosilane and pitch. So ling as spinningability temperature regions of polycarbosilane and pitch cross eath other,there can be a good spinning PC-P blender.It is valuable to the selection of components and blending process. |
