Abstract

Pure fiber-reinforced polymer composites can give protection only of a certain level of ballistic threat i.e. only of small arms ammunition. For higher ballistic threat of high energy projectiles, ballistic inserts of ceramic tiles/composite back panel are used. Such inserts are usually composed of ceramic tiles, facing the impact, laid on fiberreinforced polymer back panel where the hardness of the ceramic is the main factor contributing to the ballistic strength of the inserts. The purpose of the back panel is to keep the tiles stuck together and to be strong/rigid enough to keep the backface blunt trauma effect of the inserts under the allowed upper limit of 44 mm (1,73 inch). In this study we used pure (99,5%) alumina 5 x 5 x 0,9 cm ceramic tiles and different types of back panel high-performance composites reinforced with aramid (Kevlar), ballistic nylon, ultra-high molecular weight polyetjylene (UHMWPE, Dyneema) and glass fibers. The purpose of the study was to find the optimal back panel construction in terms of its trauma performance, weight and price level. It was shown that the lowest trauma effect could be achieved with aramid composites, the lowest weight with UHMWPE, the cheapest – with glass but with a sacrifice of the weight and ballistic nylon backpanel was somewhere between aramid and glass panels in terms of its weight and price level.
