摘　　要：通过在空气中加热沥青纤维,分析纤维在不熔化过程中析出的气相组分,同时采用付里叶变换红外光谱测定不同氧化温度下纤维的特征基因,结合热重分析和元素分析数据,对沥青纤维在空气中的氧化进行了研究,将沥青纤维的氧化大致分为三个阶段。The evolved gas-phase compositions of pitch during non-molten procedure were analysed by heating pitch fibes in the air. The characteristic radical of pitch at different oxidated temperature was measured using FTIR spectrum and the oxidation of pitch fier in the air was studied by combinating data of thermogravimetric analysis and ultimate analysis. The oxidation of pitch fiber was divided into three stages.
