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 new 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 each other,there can be a good spinning PC-P blender. It is valuable to the selection of components and blending process. |
