Ballistic response of the corrugated ceramic composite target under the impact of the flat‐headed projectile

Abstract

The ballistic responses of the composite targets composed of the corrugated ceramic block and corrugated steel plate were investigated by numerical simulation. The effects of the composite target configuration on the projectile residual velocity, the failure mode, and the energy absorption of targets were analyzed.The ballistic performance of the composite target with composites back plate was discussed. The results show that the projectile impacting on the slope of the target has the least residual velocity of projectiles, and the slope of the target can remarkably change the trajectory of the projectile. Adding the corrugated UHMWPE composites plate along the direction of the steel back plate of the configuration can effectively improve the overall anti-penetration performance of the configuration.

Effect of Z-binding depths on the ballistic performance of 3D woven through-the-thickness angle-interlock fabrics in a multiply system

“…It is revealed that the weft yarns contribute more than the warp yarns in a 3D fabric in resisting ballistic impacts. 8,13 Ma et al 14 designed a novel 3D fabric with weft yarns crimped to a similar extent as the warp yarns, and the structure exhibited improved ballistic performance. Wei et al 8 study the impact mechanism of 3DAWF under ballistic penetration, the results show that the stressed area along the weft direction is twice the size along warp direction.…”
