对硅泡沫材料的长期应力松弛进行了实验研究,得出了硅泡沫材料应力保持率与松弛时间的关系,并用现代分析测试技术对硅泡沫材料由应力松弛引起的变化进行了分析。
The long-term stress relaxation of silicon foam was experimentally studied. The relationship between stress retention and relaxation time of silicon foam was obtained. The changes of silicon foam caused by stress relaxation were analyzed by modern analytical techniques.
