Simulation of the Behavior of 32-Layer Composite Plate for Ballistic Protection

Abstract

This paper presents experimental results and a failure analysis of a composite for ballistic protection. The stratified plate is manufactured at laboratory scale, after a technology designed by the authors. The plates were tested for level FB2, taking into account the standard SR EN 1522:2004 (Windows, doors, shutters and blinds. Bullet resistance. Requirements and classification) and SR EN 1523:2004 (Windows, doors, shutters and blinds. Bullet resistance. Test method) and the results point out that this plate could face more dangerous threats. In order to evaluate the behavior of the plate under the impact characterizing a higher level of threat, the authors uses a FE model and simulated the system bullet – plate for different impact velocities.
