| 摘 要： | 利用原子氧暴露地面模拟实验装置，分别对BHM3型高模量碳纤维及其增强的氰酸酯基复合材料进行了原子氧暴露模拟实验，采用SEM、XRD、XPS技术分析了原子氧对碳纤维及其氰酸酯复合材料的侵蚀行为。结果表明，经过1×10 21 atoms/cm 2剂量的原子氧暴露后，碳纤维及其氰酸酯复合材料质量损失率均低于1%，纤维表面形貌及组成不变，碳纤维/氰酸酯复合材料的层间剪切强度降低16%。

| Abstract: | The simulation of the atomic oxygen exposure on BHM3 high-modulus carbon fibers and carbon fiber/cyanate ester (CF/CE) composites is conducted by use of the ground simulator. The atomic oxygen erosion of carbon fiber and CF/CE composites is investigated by adopting the SEM, XRD and XPS technologies. The results show that the mass loss ratios of carbon fiber and CF/CE composites are both lower than 1% when exposed to a nominal AO fluence of 1×10 21 atoms/cm 2，and the interlaminar shear strength (ILSS) of CF/CE composites decreases by 16%. |
