航天用硅橡胶制品贮存试验技术研究进展

摘要:
主要对航天用硅橡胶制品的贮存试验研究进展情况进行了梳理总结,在此基础上指出目前存在
以下三方面不足:自然贮存试验开展得少而且数据没有充分挖掘、利用;单应力加速老化试验开展得多,综合应
力加速试验开展得少;贮存试验中对产品宏观性能变化关注得多,对其微观结构变化和老化机理研究得少。针
对这些问题,指出了今后应在自然贮存试验信息的积累和应用、综合应力贮存试验和贮存老化机理等方面加强
研究。

Research Progress on Storage Aging Tests Technology ofSilicone Rubber for Spaceflight Application
Abstract:
Research progress on storage aging tests of silicone rubber for spaceflight application was reviewed
and analyzed in this paper. There are three problems in the present storage aging researches. Firstly, accelerated aging
tests (be abbreviated to AAT) were largely conducted but natural aging tests (be abbreviated to AAT) were conducted
much fewer. Secondly, AAT with a single accelerated stress was largely conducted but AAT with multi accelerated
stress was conducted much fewer. Finally, the variations of macroscopical performances had attracted too much
attention but the aging mechanism and variations of microcosmic structures were concerned too little. Based on the
problems mentioned above, three research fields including data accumulation in AAT and its applications, AAT with
multi accelerated stress and aging mechanism of silicone rubber should be emphasized in the future researches.
