Process of Preparing a Nonwoven/Filament/Woven-Fabric Sandwich Structure with Cushioning Effect of Ballistic Resistance

Non-penetrated damage is a main index that expresses the safety of bulletproof cloth in use. The kinetic energy of the bullet needs to be dissipated and dispersed by the bulletproof cloth after shooting to prevent excessive impact indentation. The nonwoven cushion structure is useful for improving the non-penetrating damage of the bulletproof cloth after a bullet is shot into it. In this work, the novel cushion material of the sandwich structure, made of the filament-laying layer and nonwoven fabric, is used to improve the properties of ballistic resistance. The design of the nonwoven cushion structure is expected to be suitable for reducing the impact indentation of the bulletproof cloth after a bullet is shot; it must be able to replace the original cushion material. The impact indentation of the bullet-shooting test can express the ability of the ballistic resistance or the resistance of the non-penetrating damage. The analytical results show that the design of the nonwoven cushion structure is effective in improving the non-penetrating damage of the bulletproof cloth after the bullet has been shot.
