Nonwoven materials have been used in ballistic protection applications because they offer the advantages of light and flexible fabrics. This study examined the ballistic protection efficacy of a nonwoven structure with high tenacity polyamide staple fiber as its main component. The nonwoven structure was reinforced with low-melt polyester fiber. High tenacity filaments were laid between two layers of polyamide webs and bonded via needle punching. The impact-resistant properties were assessed using dropped weight and bullet- shooting impact tests. The results of the dropped weight-impact test were used to examine the optimum processing conditions for composite nonwoven fabrics. Furthermore, the results of the bullet-shooting test were used to examine the ballistic protection performance of composite nonwoven fabrics. The experiment's results demonstrated that the cushion structure of composite nonwoven fabric could reduce non-penetration damage and increase the ballistic-resistant properties of bullet-resistant vest.
