| 摘 要： | 比较了单质炸药HMX和混合炸药HMX／纳米Al2O3落锤撞击试验，研究纳米α-Al2O3对HMX撞击感度的影响，并对纳米Al2O3在混合炸药中作用机理进行了探讨。结果表明，纳米α-Al2O3具有润滑作用，HMX／纳米Al2O3混合炸药的撞击感度随纳米α-Al2O30，添加量的增加而降低，添加2．0％(质量分数)纳米α-Al2O3混合炸药与单质炸药HMX相比，2．5kg落锤测试的50％爆炸特性落高(如)提高了13．1cm。

| Abstract: | The influence of nanometer-Al2O3 on the impact sensitivity of HMX/nanometer-Al2O3 was studied through testing the drop hammer impact of HMX and HMX/nanometer-Al2O3. The action mechanism of the nanometer-Al2O3 in the composite explosive was also investigated. The results indicate that the nanometer-Al2O3 has lubrication role. The impact sensitivity of HMX/nanometer-Al2O3 reduces obviously as increasing the nanometer-Al2O3 content in the composite explosive. The impact sensitivity of HMX/nanometer-Al2O3 (98/2) is higher 13.1 cm than that of HMX using 2. 5 kg drop hammer. The results can provide a valid approach for the improvement of military composite explosive impact safety. |
