采用热重、X射线衍射仪、X射线光电子能谱和拉伸试验等手段，研究了1400℃热处理对PAN基高强度碳纤维物化性能的影响。结果表明，热处理可以提高碳纤维的热稳定性和石墨化程度，减少碳纤维表面官能团的数量。由于热处理对碳纤维微观结构的影响有限，所以热处理后碳纤维的拉伸强度没有下降。
The influence of heat treatment at 1400°C on physical–chemical properties of PAN-based high strength carbon fiber was investigated by means of TG, XRD, XPS as well as the tensile test. The results showed that heat treatment could improve the thermal stability and the degree of graphitization of carbon fiber and decrease the amount of functional groups on the surface. The tensile strength of carbon fiber was not found declined after heat treatment because the change of the microstructure caused by heat treatment was limited.
