摘　　要：本工作采用连续式实骏装置与方法,借助力学测试、X射线衍射、元素分析、红外光谱等技术,系统地研究了PAN共聚纤维在连续热氧化过程中化学、结构、性能间的联系,亦对PAN基碳纤维力学性能提高的途径进行了探讨。研究结累表明:在热氧化过程中,PAN共聚体系的热化学反应主要发生在250℃左右;其间纤维的序态结构变化剧烈,易使纤维产生结构缺陷,进而影响热氧化纤维力学性能的变化。It is through X-ray, mechanical test, elemental analysis, IR, desity measurement that a research concerning the relationship between thermal reaction structure and property of PAN based fibers under constructive heat treatment at temperature from 200 to 300℃ was made, the results show that the Change of fiber mechanical property during the continuous thermooxidation is mainly depend on the physicochemical behavior and the strutural change.
