A layered charge composed of the JH-2 explosive enveloped by a thick-walled cylindrical casing (active aluminum/rubber and inert lithium fluoride/rubber composites) was designed and explosion experiments were conducted in a 1.3 m³ tank and a 113 m³ bunker. The blast parameters, including the quasistatic pressure (Δp_QS), special impulse (I), and peak overpressure (Δp_max), and images of the explosion process were recorded, and the influence of the Al content (30% and 50%) and Al particle size (1, 10, and 50 μm) on the energy release of aluminum/rubber composites were investigated. The results revealed that the use of an active layer increased the peak overpressure generated by the primary blast wave, as well as the quasistatic pressure and special impulse related to fuel burning within tens of milliseconds after detonation. When the Al content was increased from 30% to 50%, the increases of Δp_QS and I were not obvious, and Δp_max even decreased, possibly because of decreased combustion efficiency and greater absorption of the blast wave energy for layers with 50% Al. Compared with the pure JH-2 charge, the charge with 1 μm Al particles produced the highest Δp_max, indicating that better transient blast performance was generated by smaller Al particles. However, the charge with 10 μm Al particles showed the largest Δp_QS and I, suggesting that a stronger destructive effect occurred over a longer duration for charges that contained moderate 10 μm Al.

设计了由厚壁圆柱形外壳（活性铝/橡胶和惰性氟化锂/橡胶复合材料）包裹的JH-2炸药组成的分层装药，并在1.3 m ³罐和113 m ³掩体中进行了爆炸实验. 爆炸参数，包括准静态压力 (Δ p _QS )、特殊脉冲 ( I ) 和峰值超压 (Δ p _max)，记录爆炸过程的图像，研究了Al含量（30%和50%）和Al粒径（1、10和50 μm）对铝/橡胶复合材料能量释放的影响。结果表明，活性层​​的使用增加了一次冲击波产生的峰值超压，以及爆炸后数十毫秒内与燃料燃烧相关的准静压和特殊冲量。当 Al 含量从 30% 增加到 50% 时，Δ p _QS和I的增加不明显，Δ p _max甚至降低，可能是因为燃烧效率降低和 50% Al 层对冲击波能量的吸收更大。与纯 JH-2 装药相比，1 μm Al 颗粒装药产生的 Δ p _{max 最高}，表明较小的 Al 颗粒产生更好的瞬态爆炸性能。然而，具有 10 μm Al 颗粒的电荷显示出最大的Δp _QS和I，这表明对于含有中等 10 μm Al 的电荷，在更长的持续时间内发生了更强的破坏作用。
