热循环对原子氧与树脂基复合材料交互作用的影响

摘要

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.%An experimental study was conducted to determine the effects of thermal cycling on the atomic oxygen reaction with carbon-reinforced resin-matrix composites. Two types of materials were selected for this study and they are M40/DEA-1 and M40/AG-80. The calculation results of the atomic oxygen reaction rate and the interlaminar shear performance test indicate that the thermal cycling of certain cycles within a certain range may enhance the atomic oxygen resistance of the materials. In this study, the X-ray photoelectron spectroscopy (XPS) and the scanning electron microscopy (SEM) are used for the surface morphology and component analyses. The analyses have revealed the effects of the thermal cycling on the atomic oxygen reaction with carbon-reinforced resin-matrix composites.
