Abstract

This article deals with the issue of the ballistic resistance of composite panels, which were made of para-aramid fiber. For the shooting tests was used Twaron CT 747 with epoxy matrix LG 700. This material is used for soft and hard ballistic protection. The composite panels were impacted by the missile 5.56 x 45 mm NATO FMJ M139 and by the missile 5.56 x 45 mm NATO FMJ SS109. To provide the required ballistic resistance in accordance with the US STANDARD NIJ 0101.06, the composite panels were impacted by the missile 7.62 x 51 mm NATO FMJ M80. The ballistic resistance of composite panels was verified through shooting tests in the experimental ballistics laboratory. Based on the ballistic tests, we monitored the extent of the damage, the spread of cracks and delamination of layers, which allowed the evaluation of the damage of these panels. The result of the shooting tests was the determination of limit thicknesses, in which the panels will not be penetrated. These results provide essential aspects for the development of new composite armor.
