摘　　要：为了研究炭纤维在复合材料数次高温处理过程中的性能变化,选取1种国产和1种进口T300级炭纤维,进行3次2 500℃高温处理,研究了高温处理及处理次数对纤维微观形貌、线密度、晶格参数及灰分含量等性能的影响,讨论了不同的高温处理次数对不同纤维及不同性能的影响。实验结果表明,2种炭纤维的各项性能在3次高温热处理中的变化趋势相似,第1次高温处理对各纤维的性能影响最为显著。In order to research the property changes of carbon fibers through multi-times high temperature treatment,one kind of domestic carbon fiber and one kind of imported T300 grade carbon fiber were selected and implemented three times high temperature heat treatment at 2500℃.The influence of high temperature treatment and treatment times on the microstructure,linear density,lattice parameters and ash content and other properties were investigated,and the influence of different high temperature treatment times on different carbon fiber properties was discussed.The results show that through three times high temperature treatment,the trend of property changes of two kinds of carbon fibers are similar,and the influence of the first high temperature heat treatment on each carbon fiber is more evident.
