摘　　要：利用凝胶纺丝方法制备了聚丙烯腈基碳纤维原丝。采用纤维截面摄影、扫描电子显微镜(SEM)分析、溶解速度测定等方法对凝胶纺所得丝条的截面结构形态进行表征。结果表明,采用凝胶纺所得的丝条,截面形状为圆形,且表里结构均一。The PAN - based carbon fiber precursor was prepared with gel spinning method. The configuration of section of fiber prepared with gel spinning method was analyzed with photographing, SEM analysis, measuring of dissolution velocity, and so on. Result showed that the section shape of fiber prepared with gel spinning method was round and outside and inside structure was uniform.

关 键 词：溶解速度 凝胶纺 均一性
