热塑性弹性体改性B炸药的性能研究
Performance of Modified Composition B with Thermoplastic Elastomer
摘要
Abstract
Comp. B was modified by adding 2% thermoplastic elastomer 401 and 501 . For the MB-1 and MB-2 of modified Comp. B, mechanical properties and drop hammer impact sensitivity were tested, detonation performance was calculated by using experience method and VLWR code. Results show that the elasticity and toughness of the MB-1 and MB-2 were better than that of Comp. B, the toughness of MB-2 were better than that of MB-1 in low speed impact experiment. In drop hammer impact test of big-bill explosives, the threshold heights of ignition for the MB-1 was 3.5 m to 4 m, for MB-2 it was 6 m to 6.5 m. The impact sensitivity of MB-1 was higher than that of MB-2. Compared with Comp. B, the CJ velocities of the MB-1 and MB-2 decrease by about 0.104 mm · μs-1 and 0.099 mm · μs-1 , respectively; the CJ pressures of the MB-1 and MB-2 decrease by about 1.3 GPa and 1.2 GPa, respectively.关键词
