为研究“三明治”结构中的夹层材料效应对被动反应装甲设计的重要意义,文中采用试验研究和数值模拟相结合的方法,对比研究了多种材料夹层结构的抗弹机理和性能。结果表明,利用夹层材料在冲击作用下的体积膨胀和不规则变形对弹体形成侧向干扰,使弹体产生偏航是提高夹层结构抗弹能力的重要机制。新型材料超高分子量聚乙烯纤维板(UFRP)作夹层时,结构抗弹效果最好。

For studying the significance of effect of interlayer in sandwich structure to the passive reactive armor designs. In the paper, the ballistic performance and mechanism of the sandwich structure with different interlayer materials were studied based on experiment and numerical simulation. The results show that the important mechanism for improving ballistic performance of structure is lateral action to the projectile by bulging and distortion of interlayer that could make projectile yawing. The structure with the ultra-high molecular weight polyethylene fiber reinforced plate (UFRP) interlayer has the best ballistic performance.
