摘要: 紫外辐射是造成卫星外表面非金属材料性退化的主要因素之一,材料在空间使用前必须经过充分的紫外辐射效应评价。由于紫外辐照加速倍数较小(近紫外不允许超过5倍),通过地面试验实现材料在轨全周期紫外辐照暴露剂量,试验周期过长。本文介绍了典型星用功能材料紫外辐照作用下的性能退化规律和退化机理,并在此基础上提出了紫外辐照下材料性能退化模型建模方法,为解决大剂量紫外辐射下星用功能材料性能退化评价提供了一种有效手段。

Abstract: UV radiation is one of the main factors that cause the degradation of non-metal materials on the external surface of satellites. The material must be sufficient evaluated for UV radiation effect before it can be used in space. Due to UV irradiation test acceleration factor can not be too large (near-UV does not allow more than 5 times), achieving the full life UV exposure dose of the material on-orbit through ground test will take too long time. In this paper, the degradation law and degradation mechanisms of typical spacecraft functional materials under UV irradiation are introduced. The modeling method of material degradation under UV irradiation are then proposed. This provides an effective mean to solve the evaluation of functional spacecraft material degradation under high dose UV radiation.

Key words: ultraviolet radiation, functional materials, simulation test, degradation law, performance prediction
