摘要
将RDX基铝纤维炸药和RDX基含铝炸药进行水下爆炸实验,得到两种炸药在不同位置的压力-时程曲线,经过计算得到两种炸药水下爆炸的能量,并以含铝炸药的能量为铝纤维炸药的参考能量,分析两者的差异及造成差异的原因。结果表明,与含铝炸药相比,铝纤维炸药的压力峰值与冲量降低,铝纤维炸药的比冲击波能降低11%～22%,比气泡能降低11%～15%,比爆炸能降低11%～18%。铝纤维炸药的比爆炸能占爆热的73%～82%,低于含铝粉炸药比爆炸能与爆热的比值(89%～94%)。铝纤维炸药能量未达到其参考能量的主要原因是铝纤维直径较大导致反应不充分以及熔喷法制成的铝纤维中Al2O3含量较高。
Pressure-time curves were measured in different regions by underwater explosion experiments of alumi-num fiber explosive based on RDX and traditional aluminized explosive base on RDX. Explosion energy of aluminum fiber explosive and aluminized explosive were obtained by analyzing the curves, and the difference between them was analyzed and explosion energy of aluminized explosive was regarded as reference values of explosion energy of alumi- num fiber explosive. Compared to aluminized explosive, the peak pressure and the shock wave impulse of aluminum fiber explosive are decreased, the specific shock wave energy decreases by 11%-22 %, the specific bubble energy de-creases by 11%-15 %, the specific explosion energy decreases by 11%-18 %. The specific explosion energy is 73 %-82% of explosion heat, which is lower than that of aluminized explosive（89%-94%）. The results show that explo-sion energy of aluminum fiber explosive lower than the reference values because the diameter of aluminum fiber is too big to react fully and aluminum fiber which is made under high temperature contains high content of Al2O3.
