Evaluation of ballistic resistance of thermoplastic and thermoset composite panels

Abstract

In this study, the ballistic resistance of composite panels made of solid fabrics was investigated. In the experimental part, the materials Twaron CT 747 TH110 impregnated with thermoplastic resin and Twaron CT 747 impregnated with thermoset resin were examined. The ballistic resistance of the composite panels was tested in the reduced version according to the NATO AEP-55 STANAG 4569 standard, protection level 1. The manufactured composite panels were tested by the rifle cartridges 7.62 x 51 mm FMJ M80. The high-speed camera was used to observe the impact of the missiles into the panel. As part of the evaluation of the experiment, the damage ranges of these panels were identified. The composite panel made of Twaron CT 747 TH110 impregnated with thermoplastic resin absorbed more energy of the impacting missiles than the panel made of Twaron CT 747 impregnated with thermoset resin. The results show that the panel made of Twaron CT 747 TH110 impregnated with thermoplastic resin, which was composed of 90 layers was not penetrated by the missile 7.62 mm M80 and complies with NATO AEP-55 STANAG 4569, protection level 1.
