将传统含铝炸药中的铝粉用铝薄膜代替，得到铝薄膜炸药。用水下爆炸对比实验得到了铝薄膜含量为10％～40％的混合炸药与黑索今（RDX）在不同位置的压力-时程曲线。经过分析与计算得到了不同铝薄膜含量混合炸药的压力峰值、冲量、比冲击波能、比气泡能。结果表明：铝薄膜含量为10％时，铝薄膜炸药冲击波冲量相对于 RDX 提高了9％～9．5％，铝薄膜炸药比冲击波能相对于 RDX 提高了9％～12％。铝含量对铝薄膜炸药水下爆炸性能的影响不同于传统含铝炸药，主要由铝薄膜炸药的药柱结构与铝薄膜反应程度引起。%Aluminum film explosive was obtained by replacing aluminum powder in traditional aluminized explosives with alumi-num film. The pressure-time curves at different position for composite explosives with aluminum film content of 10% -40% ,and RDX were obtained by underwater explosion contrast experiments. The peak pressure,impulse,specific shock wave energy and specific bubble energy were obtained via analysis and calculation of the curves. When aluminum film content is 10% ,the impulse of aluminum film explosive relative to RDX increases by 9% -9. 5% and the specific shock wave energy relative to RDX increases by 9% -12% . The effect of aluminum film content on underwater explosion performances of aluminum film explosive is different from that of traditional aluminized explosive,which is caused by the grain structure of aluminum film explosive and the reaction extent of aluminum film.
