Experimental Study on Ballistic Performance for Multi-hole Armor Steel Plates Against the 7.62mm Armor Piercing Projectile

The ballistic performance of multi-hole and non-hole armor steel plates has been comparatively tested in the outdoor shooting range. Under conditions of 100m shot distance, 76° normal angle, the multi-hole and non-hole armor steel plates with thickness of 4mm, 5mm and 6mm all appeared typical ricochet phenomenon against the 7.62mm armor piercing projectile. The weight of multi-hole plates compared to the weight of non-hole plates can be reduced by 26.24%. Under conditions of 100m shot distance, 0° normal angle, the 6mm combined with 5mm thickness multi-hole armor steel plates and the 15mm thickness non-hole armor steel plates could both effectively protect the 7.62mm armor piercing projectile. While, the weight of multi-hole plates compared to the weight of non-hole plates can be reduced by 40.85%. The multi-hole armor steel plates have extremely broad application prospects for battlefield protection of light armored vehicles.
