In this study, high strength fabrics were coated with NRL and assembled with uncoated fabrics into several fabric systems. The fabric systems were shot with 9 mm bullets at 367 ± 9 m/s to assess the blunt trauma performances. The results showed that both the 18-layer and 21-layer uncoated fabric systems failed the blunt trauma test. However, fabric systems with NRL coated fabric layers gave lower blunt trauma of between 25 mm – 32 mm indentation depths. The modes of failure after the ballistic impact were believed to be closely related with friction among the yarns in the NRL coated fabrics. The relative measure of friction was evaluated through the yarn pull-out strength and puncture resistance tests on the uncoated and NRL coated fabrics. Higher frictional effects were evident from the NRL coated fabrics in comparison with the uncoated fabrics. back
