Abstract
The bullet-protection efficiency of the protection panel composed of various fabrics was examined in this study. Two different types of aramid woven fabrics and two different types of fiber-reinforced composite (FRC) with/without polymeric film were examined. The physical properties such as tensile and tear strength were evaluated to inspect a relationship between the properties of materials and bullet-protection efficiency. Bullet-protection performance of stacked materials was evaluated using lab scale drop tester. The protection efficiency was determined by depth and diameter of trauma embedded on a backing clay. Results showed that the fabrication method and material had significant effect on bullet-protection efficiency. The FRCs demonstrated the better bullet resisting performance compared to the woven type materials considering the weight and thickness of stacked samples. Especially FRC with the polymeric film resulted in reduction of trauma significantly. However, the type of polymeric film should be carefully selected to attain efficient bullet resistance property because the protection efficiency was differentiated by the type of film.
