| 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。 |

| Abstract: | Two kinds of unidirectional laminates made of carbon/cyanate composite named M40/DFA-1 & M40/DFA-N3(nano TiO 2 contained) 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 of 1.5×1020 cm-2 atomic 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-N3 sample 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 TiO2 granules, which leads to a higher proportion of C=O bonds generated. |
