| 摘 要： | 有机聚丙烯腈纤维（PANF）经过一系列高温热处理（HTT）转化为无机碳纤维（CF），CF属于脆性材料，其抗拉强度受控于各类缺陷，它的缺陷大致可分为两大类，一类是先天性缺陷，即由原丝引入，另一类是后天性缺陷，在后处理过程中引入，本文主要是用扫描电子显微镜（SEM）研究PAN原丝的表面缺陷。

| Abstract: | Having been high temperature treated, the organic PANF are transferred to the inorganic carbon fiber. The carbon fiber belongs to the fragile materials and the strength is controlled by the kinds of weakness, including the innate ones and the acquired ones, which is imported by the precursors and the aftertreated process separately. The articles studies the surface shortcomings of PAN precursors by SEM |
