文章选取M40/DFA-1和M40/AG-80两种碳纤维增强树脂基复合材料,进行了热循环对原子氧与这两种材料交互作用影响的研究。原子氧反应率的计算和层间剪切性能测试的结果表明,一定温度区间一定次数的热循环使得材料与原子氧交互作用减弱。该研究应用X射线光电子能谱仪(XPS)和扫描电子显微镜(SEM)对样品表面成分和形貌进行了分析。根据分析结果,初步提出热循环对增强树脂基复合材料自身抗原子氧侵蚀能力的作用机理。 In this paper, two types of carbon fiber reinforced resin matrix composites, M40 / DFA-1 and M40 / AG-80, were selected to study the effect of thermal cycling on the interaction between atomic oxygen and these two materials. The calculation of atomic oxygen reaction rate and the test of interlaminar shear properties show that the thermal cycling at a certain temperature interval reduces the interaction between the material and atomic oxygen. In this study, the surface composition and morphology of the samples were analyzed by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). According to the results of the analysis, the mechanism of thermal cycling on enhancing the erosion resistance of the resin-based composite with its own anti-oxygen has been proposed.
