摘要
为探究活性材料与炸药组合装药的爆轰特性,制备一种Al/PTFE/TiH_(2)三元活性材料与RDX炸药的组合装药。利用空中爆炸实验并结合比色测温技术,研究TiH_(2)粉末含量对组合装药爆轰性能及后燃效应的影响。研究结果表明:随着TiH_(2)粉末含量的增加,组合装药的冲击波参数、爆炸火球持续时间以及最高平均温度皆呈先上升、后下降的趋势,且均在TiH_(2)粉末含量为10%时达到最大值,相较于不含TiH_(2)粉末的组合装药,其冲击波峰值压力、爆炸火球持续时间以及最高平均温度分别提升了21.6%、105.9%和7.1%;通过对比TiH_(2)粉末和Ti粉末对组合装药爆炸释能特性的影响,发现由于游离氢参与后燃反应,使得TiH_(2)粉末对组合装药爆炸冲击波参数和爆炸火球温度场的增益效应优于Ti粉末;研究成果可为Al/PTFE/TiH_(2)三元活性材料在组合装药中的应用设计及武器毁伤评估提供参考。
To investigate the detonation characteristics of composite charges containing the reactive materials and explosives,a composite charge containing Al/PTFE/TiH_(2)ternary reactive materials and RDX explosives is prepared.The influences of TiH_(2)powder content on detonation performance and afterburning effect are systematically studied by the air blast experiment and the colorimetric temperature measurement technology.The experimental results show that the shock wave parameters,explosion fireball duration and maximum average temperature of the composite charges increase first and then decrease with the increase in TiH_(2)powder content,reaching the maximum values when the content of TiH_(2)powders is 10%.Compared with the composite charge without TiH_(2)powders,the shock wave peak pressure,explosion fireball duration and maximum average temperature of composite charges containing 10%of TiH_(2)powders are increased by 21.6%,105.9%and 7.1%,respectively.Furthermore,the effects of TiH_(2)and Ti powders on the explosion energy release characteristics of composite charges are compared.It is found that the enhancement effects of TiH_(2)powders on the explosion shock wave parameters and fireball temperature field of the composite charge are superior to those of Ti powders due to the participation of free hydrogen in the afterburning reaction.The research results can provide valuable references for the application design of Al/PTFE/TiH_(2)ternary reactive materials for composite charges as well as the weapon damage assessment.
