| 摘 要： | 用硼化合物对碳纤维进行抗氧化处理,提高了纤维的高温抗氧化性能。用热分析、电子显显微镜、表面电子能谱和X射线衍射等进行了研究,结果表明:碳纤维经过硼化合物处理后,氧化活化能提高123.4%,热氧化分解点提高268℃,高温使用寿命提高许多倍,但物理机械性能变化不大。

| Abstract: | The anti-oxidation performance of carbon fiber in high temperature atmosphere was increased greatly after it was treated with boron agents.It was shown by means of TGA,SEM,XPS and WAXD that the treatment elevated the decomposition point above 268℃, and increased the average oxidation activation energy doubly,from 98.6kJ/mol of the untreated fiber to 220.3kJ/mol of the treated fiber,with the first order of the fiber oxidation reaction under non-isothermal conditions,and increased the life-time many times.During the process,however,the mechanical properties developed slightly. |
