NUMERICAL MODELING OF BALLISTIC RESISTANCE OF THERMOPLASTIC LAMINATE UNDER 9 X 19 MM PARABELLUM AMMUNITION

Abstract

This paper presents the examination of laminates on a thermoplastic polypropylene (PP) matrix. A preliminary homogenization of the system was performed using a scanning electron microscope (SEM). Numerical simulations were carried out and the energy dissipation of 9x19 mm Parabellum with a velocity of 360 m/s ± 10 m/s was analyzed. The results of the simulation were compared to real samples after their overshot in the ballistic test. The aim of the study was to determine the ballistic limit of material systems intended for ballistic protection against pistol and revolver bullets. The optimization of laminates for personal protection was aimed at reducing Back Face Deformation (BFD), which is the replacement measure for blunt force trauma.
