对碳／碳复合材料的氧化行为进行了较系统的研究。通过对材料氧化后的质量损失和显微形貌的观察，指出内部缺陷和浸渍碳石墨化程度较低是导致复合材料氧化性较差的内在因素，讨论了温度和时间对氧化侵蚀的影响，提出了浸渍碳和碳纤维氧化过程的模型
The oxidation behavior of carbon / carbon composites has been studied systematically. Through the observation of mass loss and microstructure after the oxidation of the material, it is pointed out that the internal defects and the low degree of impregnated carbon graphitization are the intrinsic factors leading to the poor oxidation of the composites. The effects of temperature and time on the oxidative erosion are discussed. A model for the oxidation of carbon and carbon fiber was proposed
