| 摘 要： | 为研制高能量密度无铅的火工药剂,以纳米铝粉和纳米氧化钼为原料,采用超声分散混合的方法,制备了绿色环保的纳米含能材料Al-MoO3。通过冷场扫描电镜和差热分析(DSC)对纳米含能材料Al-MoO3进行了表征分析,制作了电点火头和激光点火头,进行了点火性能测试。结果表明:纳米含能材料Al-MoO3在520℃以上的高温条件下反应,放出大量的热,其中电点火头的50%的电压发火感度为22.8V,激光点火头的50%的发火感度为5.1mJ。

| Abstract: | The nano-energetic materials Al-MoO3 is prepared by immersing the powders in a solvent and then mixing the two powders including nano-Al and MoO3 using an ultrasonic mixer. The performance of nano-energetic materials Al-MoO3 was analyzed by means of Scanning Electron Microscopy (SEM) and Differential Scanning Calorimetry (DSC). Preparedand electrical match and laser match, and ignition sensitivity were tested. The study shows that nano-energetic materials Al-MoO3 is reaction under high temperature giving out lots of heat, voltage ignition sensitivity and electricity ignition sensitivity of electrical match and laser ignition sensitivity of laser match,its 50% sensitivity is 22.8V, 462mA and 5.1mJ respectively. |
