聚丙烯腈基纤维和沥青基纤维微波预氧化研究

Study on Microwave Preoxidation of Polyacrylonitrile-based Fiber and Asphalt-based Fiber

为了更好的将微波加热技术应用到碳纤维原丝的预氧化过程中,研究了聚丙烯腈基纤维和沥青基纤维与微波的相互作用关系。采用FTIR和XRD检测手段分析两者在加热过程中化学结构和晶体结构的差异,以获得最佳的微波处理方式。

In order to apply the microwave heating technology to the pre-oxidation process of carbon fiber precursors,the interaction between polyacrylonitrile-based fibers and pitch-based fibers and microwaves was studied in this paper.FTIR and XRD detection methods were used to analyze the differences in the chemical structure and crystal structure during the heating process to obtain the best microwave processing method.
