中文摘要:
      为了获得同时具有较高力学性能和释能密度,本文采用电沉积及热压复合法制备了层状Al/Ni含能结构材料。研究了热压温度对Al/Ni含能结构材料放热反应性能的影响。并通过打靶实验获得了不同发射速度下含能破片对双层靶板的毁伤效果。结果表明:随着热压温度的升高,Al/Ni界面反应扩散加剧,导致放热量从898 J/g降低至782 J/g。高速撞击作用下,Al/Ni含能破片发生了剧烈的爆燃反应,对双层靶板有显著的毁伤效应。当含能破片撞击速度从1241 m/s增加到1478 m/s时,主靶板穿孔尺寸几乎不变,后效靶板的毁伤区域明显增大。
Exothermic Properties and Damage Effects of MultilayeredAl/Ni Energetic Structural Materials

英文摘要:
      In order to obtain both high mechanical properties and released energy density, multilayered Al/Ni energetic structural materials were prepared by electrodeposition and hot pressing method in this paper. The effect of hot pressing temperature on the exothermic properties of Al/Ni energetic structural materials was studied. The damage effect of the energetic fragment on double target boards at various impact velocities was obtained through shooting experiments. The results showed that with the increase of the hot pressing temperature, the diffusion reaction at Al/Ni interfaces increased, leading to a decrease of exothermic heat from 898 J/g to 782 J/g. Under high-speed impact, the Al/Ni energetic fragment experienced a violent deflagration reaction, which had a significant damage effect on the double target boards. When the impact velocity of the energetic fragment increased from 1241 m/s to 1478 m/s, the perforation size of the main target plate was almost unchanged, however the damage area of the after-effect target plate increased significantly.
