采用7.62 mm × 51 mm穿甲弹对镶嵌碳化硅（SiC）陶瓷与超高分子量聚乙烯（UHMWPE）板的抗弹性能进行了试验研究。系统研究了SiC陶瓷对镶嵌SiC/UHMWPE复合装甲抗弹性能的影响，详细阐述了硬脆SiC与软柔性UHMWPE相结合的复合装甲的防弹工艺。试验结果表明，镶嵌SiC陶瓷的几何形状和前层冲击区对复合装甲的抗弹性能有显著影响，对于圆柱形镶嵌SiC/UHMWPE复合装甲，确定了不同的冲击区。当子弹发射速度为780 m/s时，对于圆柱形、六边形和方形镶嵌SiC陶瓷，AP弹丸的剩余速度变化范围为648 ~ 0 m/s，标准偏差为10 m/s。对于不同的镶嵌SiC陶瓷前层结构，UHMWPE板的凸出长度也从16.5 mm变化到43.2 mm。延长子弹与靶板的作用时间可以显著提高其防弹性能。本文的结论对硬/柔复合装甲系统的设计具有实际意义。
Experimental study on the ballistic behavior of mosaic Silicon Carbide (SiC) ceramics bonding with Ultra-High Molecular Weight Polyethylene (UHMWPE) plate is presented against 7.62 mmx51 mm Armor Piercing (AP) projectile. The effect of SiC ceramics on the ballistic performance of mosaic SiC/UHMWPE composite armors is systematically investigated, and the bulletproof process of the composite armor combining the hard/brittle SiC and soft/flexible UHMWPE is clarified in detail. The test results show that the ballistic performance of composite armors is significant influenced by the geometry of mosaic SiC ceramics and the impact zone of front layer, different impact zones are defined for the cylindrical mosaic SiC/UHMWPE composite armor. The residual velocities of AP projectile are varied from 648 m/s to 0 m/s for the cylindrical, hexagonal and square mosaic SiC ceramics, when the launch speeds of bullets are 780 m/s with a standard deviation of 10 m/s. The bulge lengths of UHMWPE plate are also changed from 16.5 mm to 43.2 mm for different structures of mosaic SiC ceramic front layer. The bulletproof property can be significantly enhanced by prolonging the interaction time between bullet and target. The conclusions of this paper are practically useful for designing the hard/flexible composite armor systems.
