| 摘 要： | 对PBO-AS单丝实施拉伸，通过观察拉伸断裂后的单丝形态，分析单丝断裂强力同单丝微观结构的关系．通过显微镜观察发现，PBO断裂后的单丝微观结构发生变化．提出单丝本身结构和原纤化可能是导致这些结果的主要原因．

| Abstract: | In order to understand the relation between single PBO-AS fibers stress and their microstructure, the tension test was carried out and the changed structure of the fiber was observed with microscopy. It is found that there are some nodes, buckles in the break fibers and their structure become loose after breaking. It is supposed that the fibrillated is main reason contribute to these result. |
