Abstract

The work reports on numerical simulation of impact problems on ceramic/aramid armour systems backed with Kevlar 29. Tests were performed with STANAG 2920 fragments and NATO 5.56 bullets driven at velocities up to 1100m/s. In order to obtain the best ballistic efficiency of the composite armour system three configurations of the armour system was taken into account in numerical simulations, varying the thickness of ceramic front plate. The thickness of backed plate was maintained constant at 2 mm. The configurations are contemplated in the table 1.

Configuration Ceramic/Kevlar thickness ratio (h1/h2)
C1 5
C2 7.5
C3 9.5

The ballistic performance of the lightweight armour systems was examined to obtain an estimate for the global damage of the composite plates.
