Experimental investigation of laminated rubberized aramid armor plates resisting.30 caliber fragment simulating projectile impact

Abstract

Establishing the survivability for armed forces and police teams, attentive solutions are needed owing to the damage mechanism of fragments that have more kinetic energy than traditional bullets. Nevertheless, determining the damage capability of composite laminates against fragment impact at ballistic velocities is a challenging issue because of the difficulty in determining elastic stiffness of the armor due to the complex damage modes, which can occur in composites through impact phenomenon. Fire tests are generally considered to be the best validation method for procurement transactions of customers. This study presents the effects of impact velocities for rubberized aramid plates on the basis of computerized tomography scans taking into consideration composite failure modes. Additionally, the impact damage of plates at different ballistic velocities is presented, supported by real test reports focusing on the penetrating prevention capability and a predictive equation of ballistic limit velocity for rubberized aramid plates resisting. 30 caliber FSP is developed.
