The rubber materials were suitable for the cushion structure. This investigation used the adhesive sealant of Chloroprene rubber to combine two layers of polyamide nonwoven fabrics and form a sandwich structure. The Nylon/rubber compound nonwoven fabrics were placed inside the multi-layer Kevlar fabrics, which included the plain weaving and unidirectional fabrics. This work used the dropping impact test to measure the comparative impact resistance of the multi-layer Kevlar complex fabrics under various forming conditions. This study also evaluated the cushion effect based on the impact energy in the dropping impact test. The adhesive sealant of Chloroprene rubber was expected to. be useful for the cushion effect of multi-layer Kevlar complex fabrics. This investigation altered the content of the low melting-temperature polyester staple fiber and the needle punching density that could influence the adhesion between two layers of nonwoven fabrics, and discussed the influences of these parameters on the fracture propagation energy of multi-layer Kevlar complex fabrics. The analytical results demonstrated that the Chloroprene rubber is useful for increasing the cushion effect in suitable formation conditions.
