设计了一种称为阵列式陶瓷颗粒破片防护层的新型防弹材料,并对材料的防弹性能进行了仿真研究。当破片侵彻防护层的不同位置时,陶瓷颗粒的破碎情况有所不同,可能发生整体破碎或部分破碎。陶瓷颗粒能在极短的时间内使高速破片的速度降到100m/s以内,然后破片速度进入平台下降期,在0.1ms时刻破片的速度均下降到40m/s以下。研究结果可以为阵列式陶瓷颗粒破片防护层的优化设计提供参考。

The array ceramic grains bullet resistant material was designed and the bullet-proof performance of it was researched by simulation. When fragment penetrates the material in different places, the case of ceramic grains breaking is different from others, and the grains could break entirely or partly. In all case, the velocity of fragment can be reduced to 100m/s, and then the velocity falls down slowly, and below 40m/s at 0.1ms. It can offer information to optimize the material.
