摘要
空间环境是一个极为复杂的环境,材料在空间环境下使用不可避免地受到环境中多重因素同时作用的影响,材料的力学、物理、化学性质发生变化,性能失效。要准确认识和评价材料在空间环境下的性能,必须采取正确有效的表征和研究方法。介绍了空间环境的基本特征,空间环境下材料老化性能表征的常用方法和装置,柔性材料在热、光、真空原子氧单独及复合作用下的老化性能的研究现状及目前存在的主要问题,同时还指出了空间环境复合作用下表征存在的主要问题,为正确评价材料在空间环境下的性能提供参考。
The space environment environment are inevitably influenced properties change, and some function is an extremely complex one. The materials being applied in this by multiple factors simultaneously, the mechanical and physical chemical s may lose. To know and evaluate the properties of materials in the space environment, we must adopt effective characterization and research methods. The scope of this presentation includes the basic characteristics, measurement methods and instruments for characterization of materials aging properties in the space environment, the domestic and foreign research status and existing problems of flexible materials aging properties under thermal, photo, vacuum, atomic and compound environments. Meanwhile, the main existing problems in characterization in the space environment are discussed. The study provides some guidance for evaluating the materials properties in space environment.
