Problems solved by technology

In terms of bulletproof capability, the existing soft bulletproof materials (usually multi-sheet surface density of 160g / m 2 The left and right UD sheets are superimposed) can generally prevent bullets fired by pistols and submachine guns beyond 5m, but the back convex depth is relatively large (close to the critical value specified in the standard), and the bulletproof performance needs to be improved

Abstract

The invention provides a UHMWPE fiber reinforced resin-based soft bulletproof material, and relates to the technical field of protective equipment. The soft bulletproof material comprises a middle layer, a bullet facing surface layer overlaid on the surface of one side of the middle layer, and a bullet backing surface layer overlaid on the surface of the other side of the middle layer. The woven composite material is used as a bullet-facing surface layer material and a bullet-backing surface layer material of the soft bulletproof material, and the woven composite material is formed by making UHMWPE fibers into plain cloth or twill cloth and then hot-pressing and compounding the plain cloth or twill cloth and a hot-melt resin adhesive film. A plurality of UD sheets are used as middle layermaterials, each UD sheet is formed by hot-pressing and compounding a plurality of layers of UD single sheets, every two adjacent layers of UD single sheets are orthogonally arranged, and each UD single sheet is prepared from UHMWPE fibers and thermoplastic resin according to a UD cloth forming method. The soft bulletproof material is light in weight and has excellent bulletproof performance.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a UHMWPE fiber-reinforced resin-based soft bulletproof material. Background technique [0002] The development of weapons has prompted corresponding progress in body armor. Bulletproof vest materials are mainly hard bulletproof materials made of special steel, aluminum alloy and other metals at first. This kind of bulletproof vest has certain bulletproof performance, but the clothes are thick and uncomfortable to wear, which greatly restricts human activities and is prone to damage. secondary debris. In order to improve the wearing comfort of bulletproof vests, soft bulletproof materials are produced thereupon. Soft bulletproof materials are light in weight, relatively soft in texture, good in fit, and have good concealment when worn inside. In terms of bulletproof capability, the existing soft bulletproof materials (usually multi-sheet surface density of 160g / m ...
