摘要

摘要: 将铝纤维炸药与传统铝粉炸药和RDX炸药进行空中爆炸实验并得到压力时程曲线，经过分析计算得到3种炸药的压力峰值、二次击波、正相持续时间以及冲量。结果表明：铝纤维炸药的压力峰值相对于RDX没有明显提高，但其压力时程曲线衰减速度慢于RDX的，使铝纤维炸药的正相持续时间大于RDX，铝纤维炸药的冲击波冲量相对于RDX的平均提高了18%，与铝粉炸药的相当。铝纤维炸药的二次击波超压幅值与到达时间与铝粉炸药的接近，而铝纤维炸药的二次击波到达时间早于RDX，说明二次击波的超压幅值与到达时间与炸药类型有关。

Abstract: The pressure history curves of aluminum fiber explosive and traditional aluminized explosives were measured by air blast experiments, and then the peak pressure, the secondary shock wave, the time of positive phase and the impulse were obtained by analyzing the curves. The result show that the peak pressure of the aluminum fiber explosive is not improved obviously with regard to the matrix explosives (RDX). The pressure decay rate of the aluminum fiber explosive is slower than that of RDX, resulting in that the time of the positive phase of the aluminum fiber explosive is longer than that of RDX. Compared with RDX, the impulse of the aluminum fiber explosive increases on the average by 18%, close to that of the traditional aluminized explosive. The amplitude and the occurrence of the secondary shock wave of the aluminum fiber explosive are the same as the traditional aluminized explosives and the secondary shock wave of aluminum fiber explosive occurs earlier than the matrix explosives (RDX), which shows that the amplitude and the occurrence time of the secondary shock wave are correlated with the types of explosive.
