Abstract

This paper presents the possibility of using additional ballistic shields based on composite materials, which are applied to the body of a passenger car. A ballistic laminate made of Twaron T 750 aramid fabric with 5 mm thick and 2 mm thick magnetic foil was used. In the first stage, the mechanical parameters of the tested ballistic laminate system were determined in tensile tests. In field tests, the considered system was analyzed in terms of impact with a 9 × 19 mm FMJ Parabellum projectile, and then the results were numerically verified. The work was focused on the validation of numerical models. The appropriate correlation level of the numerical results was obtained with the fit, which was estimated at approximately 7%; furthermore, the results prove the correctness of this study’s research methodology.
