    摘要:

    为研究锦纶材料在长寿命在轨航天器中的环境适应性,提出了锦纶材料在空间环境使用的空间环境适应性评价指标,设计并实施了空间环境适应性评价试验。试验结果表明,锦纶材料在燃烧性能、逸出有害气体、真空质损和可凝挥发物、抗菌防霉、耐受交变温度、电离辐射中表现出友好的环境适应性。锦纶材料在受到空间环境中原子氧、紫外辐射作用时断裂强力明显下降,且原子氧与紫外辐照协同效果对锦纶材料的力学性能破坏具有加强效果。锦纶材料可作为空间舱内环境长期使用材料,在舱外环境使用时,需要特别考虑其力学特性受到原子氧、紫外辐照的影响。

    Abstract:

    In order to study the environmental adaptability of nylon in long-life in-orbit spacecraft, space environmental adaptability evaluation indexes of nylon in space environment were proposed, and space environmental adaptability evaluation tests were designed and implemented.The test results show that the nylon shows friendly environmental adaptability in combustion heat, escaping harmful gases, vacuum mass loss and condensable volatiles, antibacterial and mildew resistance, tolerance to alternating temperature, and ionizing radiation. The fracture strength of nylon decreases significantly when subjected to atomic oxygen and ultraviolet radiation in space environment, and the synergistic effect of atomic oxygen and ultraviolet irradiation has a strengthening effect on the mechanical property damage of nylon. The nylon could be used as a material for long-term use in the space cabin environment, When used in the extravestrated environment, special consideration should be given to its mechanical properties under the influence of atomic oxygen and ultraviolet radiation.
