空间用非金属材料挥发特性分析

Analysis of Nonmetallic Material Using in Astrospace

介绍了在空间环境条件下,各种特殊效应对于材料产生的不利影响;阐述了空间用非金属材料的选用原则、选用范围和选用要求;重点介绍了挥发物试验的主要方法,并给出了10种非金属材料的可凝挥发物和总质量损失的测试结果;针对测试数据进行了分析,给出了测试样品在具体使用过程中的建议。航天电子电气产品应优选总质量损失小、可凝挥发物低的材料;对于一些不满足指标要求又无法找到合适替代物的材料应通过控制其使用位置等方法加以严格控制。

The blight on material in astrospace environment is introduced. The principle, the extension and the demand of the nonmetallic material using in astrospace are expatiated. The method of volatile material test is introduced. The results of TML and VCVM test from ten kinds of nonmetallic material are given. To the results of the testing data, the suggestion for every kind of material is listed. For some incongruent materials, it is necessary to control it strictly.
