摘　　要：选取具有良好应用前景的M40/DFA-1、M40/DFA-N3(添加TiO2纳米颗粒)碳纤维增强氰酸酯基复合材料为研究对象,开展航天器在轨原子氧环境地面模拟试验,通过表面/断口形貌观察、质量损失测试、层间剪切强度测试以及表面成分分析等方式,分析探讨了上述2种碳/氰酸酯基复合材料的原子氧损伤效应。结果表明,在原子氧的作用下,2种材料表面树脂均受到了一定程度的剥蚀,添加纳米颗粒的M40/DFA-N3质损率及原子氧剥蚀率相对更高,但层间剪切强度下降幅度相对较小,这可能是由于其氧化反应更加剧烈,生成的碳氧双键比例更高的结果。Two kinds of unidirectional laminates made of carbon/cyanate composite named M40/DFA-1&M40/DFA-N3(nano TiO2contained)are selected for studying the effects of atomic oxygen interactions.Based on the ground simulation of atomic oxygen environment,several tests are conducted,such as the surface/fracture morphology observation,the mass loss test,the inter-laminar shear strength test,and the X-ray photoelectron analysis of surface components.After the exposure of1.5×10^20cm^-2atomic oxygen,the surface detachment is observed on both types of materials.In addition,the mass loss as well as the erosion rate are calculated.It is shown that the M40/DFA-N3sample exhibits relatively higher mass loss and erosion rate while with a smaller decrease of the inter-laminar shear strength compared with the specimens made of M40/DFA-1.It can be partly attributed to the drastic oxidation reaction within the nano TiO2granules,which leads to a higher proportion of C=O bonds generated.
