摘要
通过对某随弹贮存8 a的硅橡胶密封材料进行外观检查、常规物理性能检测、恒定压缩永久变形测试及加速贮存试验,获得了橡胶材料的各项物理性能,用压缩永久变形临界值作为判据得到了25℃下硅橡胶密封材料可继续贮存使用的寿命预估值,为该型导弹寿命预估提供了重要理论依据。
Appearance inspection, normal physical performance examination, constant compression deformation test, and accelerated aging were carried out on the silicone-rubber sealing material which was disassembled from a missile of 8 years storage. The physical performance was gotten, and the added storage life of the silicone-rubber sealing material was predicted using the criterion of constant compression deformation. The purpose was to provide reference for life prediction of the missile.
