Bullet-proof Performance of Ceramic Composite Armors against 14. 5 mm Armor-piercing Projectiles

Large-caliber anti-armor weapons are playing an increasingly important role in the battlefield，and higher requirements are put forward for the armor materials and structure design. In order to explore the bulllet-proof mechanisms and performance of ceramic composite armor penetrated by 14.5 mm armor-piercing projectile，an armor structure with ceramic/fiber/metal/flexible material/metal layup configuration was designed，and the influences of thickness matching，bottom plate material and flexible material on the ballistic performance were discussed through experiments.The results show that the thickness of ceramic plate has an influence on the bullet-proof performance significantly，and when the thickness of ceramic plate is 1.38 times of the core diameter，the targets have excellent bullet-proof performance. For the similar surface density and the constant ceramic thickness，the dimension matching of the composite rear plates has little influence on the bullet-proof performance when changing in a certain range.For the similar surface density，the thickness of the bottom plate should be larger when the armored aluminum is selected，and the anti-penetration performance is better. The flexible material can not only decrease the damage area，but also make the projectile yawed and change the incidence angle of projectile，thus improving the protective performance of the composite armor.
