Abstract

The goal of the study is to investigate the behavior of composites made of Aramid (aromatic polyamide) fibers as reinforcements and modified phenolic resin as matrix, under ballistic impact. Aramid fibers are extremely strong and tough and are very widely used for manufacture of personal protection items. Besides their inherent resistance to impact, a big influence on the ballistic properties of their composites can have matrix content as well as processing parameters. We have studied two types of woven fabrics composites with the resin content of 20% and 50% and the areal weight 2 – 9 kg/m2. Some of the composites are molded at on our 200 tons press and we have measured their trauma effect i.e. the deformation of the back face of the panel. The best ballistic strength have shown composites with ~20% resin content and the worst those with ~50% resin content. Trauma effect was less pronounced by high-pressure composites contrary to the low-pressure ones which have shown the highest trauma effect. Generally, the composites with ~20% resin content molded at the highest pressure have shown both, the ballistic toughness and the lowest trauma on the back side of the panel.
