In this paper, the ballistic impact experiments, including impact test chamber and impact double-spaced plates, were conducted to study the reaction behaviors of a novel functionally graded reactive material (FGRM), which was composed of polytetrafluoroethylene/aluminum (PTFE/Al) and PTFE/Al/bismuth trioxide (Bi₂O₃). The experiments showed that the impact direction of the FGRM had a significant effect on the reaction. With the same impact velocity, when the first impact material was PTFE/Al/Bi₂O₃, compared with first impact material PTFE/Al, the FGRM induced higher overpressure in the test chamber and larger damaged area of double-spaced plates. The theoretical model, which considered the shock wave generation and propagation, the effect of the shock wave on reaction efficiency, and penetration behaviors, was developed to analyze the reaction behaviors of the FGRM. The model predicted first impact material of the FGRM with a higher shock impedance was conducive to the reaction of reactive materials. The conclusion of this study provides significant information about the design and application of reactive materials.

在本文中，进行了包括冲击试验室和冲击双间隔板在内的弹道冲击实验，研究了一种由聚四氟乙烯/铝（PTFE/Al）组成的新型功能梯度反应材料（FGRM）的反应行为。和PTFE/Al/三氧化铋（Bi ₂ O ₃）。实验表明，FGRM 的撞击方向对反应有显着影响。在相同的冲击速度下，当第一冲击材料为 PTFE/Al/Bi ₂ O _{3 时}，与第一冲击材料 PTFE/Al 相比，FGRM 在测试室中引起更高的超压和更大的双间隔板损坏面积。建立了考虑冲击波的产生和传播、冲击波对反应效率的影响以及穿透行为的理论模型，以分析 FGRM 的反应行为。该模型预测具有较高冲击阻抗的 FGRM 的第一冲击材料有利于反应材料的反应。本研究的结论为反应性材料的设计和应用提供了重要信息。
