用于测试热固性浇注PBX固化应力的应变片组件及测试方法
摘要：
本发明涉及用于测试热固性浇注PBX固化应力的应变片组件及测试方法。所涉及的用于测试热固性浇注PBX固化应力的应变片组件包括基材和包覆在基材中的应变片，所述应变片在所述基材中呈平铺状，所述基材的成分为：端羟基聚丁二烯、己二酸二辛酯、铝粉、2,4-甲苯二异氰酸酯和三苯基铋。所涉及的热固性浇注PBX固化应力的测试方法包括、应变片组件的校准、布置应变片组件和浇注弹体及固化过程应力的测试。本发明的应变片组件可以随意的放入浇注PBX内部的不同位置，在测试过程中基材与药浆相容性好，有了基材的保护应变片不会卷曲也不会受到液态药浆的腐蚀，对浇注PBX固化应力的测试效果显著。
摘要（英）：

The invention relates to a strain gauge assembly for testing the curing stress of a thermosetting pouring PBX and a testing method thereof. The strain gauge assembly for testing the curing stress of the thermosetting pouring PBX comprises a base material and a strain gauge which is wrapped in the base material, the strain gauge is in a tiling shape in the base material, and the base material is composed of hydroxyl-terminated polybutadiene, dioctyl adipate, aluminite powder, 2/4- toluene diisocynate and triphenylbismuthine. The testing method of the curing stress of the thermosetting pouring PBX comprises the steps of calibrating the strain gauge assembly, arranging the strain gauge assembly, pouring an elastic body, and testing the stress in the curing process. The strain gauge assembly can be randomly placed at different positions in the pouring PBX, in the testing process, the compatibility of the base material and chemical slurry is good, the strain gage can not be curled or corroded by liquid chemical slurry due to the protection of the base material, and the testing effect on the curing stress of the pouring PBX is obvious.
