Four kinds of finite thickness target plates were prepared, including granite (G) plates, steel wire-mesh reinforced concrete (RC) plates, composite GRC targets composed by granite (G) plates and steel wire-mesh reinforced concrete (RC) plates, and composite GBRC targets composed by granite block (GB)masonry and steel wire-mesh reinforced concrete (RC) plates. By using a 30-mm-caliber gun to accelerate two kinds of projectiles of the same shape which differ in material strength, penetration experiments were carried out for these prepared target plates, respectively. The damage effects of the target plates subjected to projectile penetration were compared. The results show that the well-designed GBRC targets have the best resistance to perforation. And the perforation resistance of the GBRC targets is closely related with the following factors: block stone size, strength, masonry way, and reinforced concrete structure.
