The aim of our work presented was to design a new bullet-proof material with cushioning effect of ballistic resistance. We prepared a multilayer sandwich structure of a PA6/PET ( polyamide/polyester) nonwoven, PET (polyester ) filament layer, and a polyaramide (Kevlar) woven fabric. The laminated structure is useful for transmitting the impact stress. In this study, the spread polyester filament was laid on the pre-punching polyamide web with low melting-temperature polyester staple fibres to form a sandwich structure by being covered with another web. After the bonding of needle punching and the thermal calendering, the compound nonwoven fabrics were obtained. The vertical bundle structure of the fibres formed by needle punching is helpful in energy trasmission. The analytical results show that the sandwich structure is useful for the cushion material of the bulletproof cloth. Through structural design, the impact indentation of the bulletproof cloth after bullet shooting is improved to decrease the non-penetrating damage to the human body. Additionally, the performance of the ballistic resistance can be raised. The better cushioning effect is expected at a lower cost.
