Problems solved by technology

[0004] However, due to the chemical properties of high hydrophobicity and low surface activity of UHMWPE fibers, the surface of the fibers is very smooth and the coefficient of friction is small, and the cohesion between fibers is low, which is not conducive to spinning and weaving. Poor interface bonding is prone to occur when making protective products, which not only affects the process yield and product cost, but may also detract from the stab-proof, bullet-proof, explosion-proof and durability performance of the protective products.

Abstract

The invention relates to an impact-resistant composite structure, which comprises a first fabric, a second fabric layer, a non-woven fabric, a fiber resin layer and a polymer adhesive, wherein the first fabric comprises a surface weave surface and an inner weave surface, the surface weave surface and the inner weave surface are opposite to each other, the thickness between the surface weave surface and the inner weave surface is not smaller than 2.0 mm, the second fabric layer has a front weave surface and a rear weave surface, the fiber tensile strength of the front weave surface and the rearweave surface is not less than 10 g / d, the non-woven fabric is clamped between the inner weave surface of the first fabric and the front weave surface of the second fabric layer, the fiber resin layer is provided with a roughened surface, the roughened surface is attached to the rear tissue surface of the second fabric layer, and the first fabric, the non-woven fabric, the second fabric layer andthe fiber resin layer are adhered by the polymer adhesive.

Description

technical field [0001] The present invention relates to a protective structure, and in particular to an impact-resistant composite structure with anti-stab, bullet-proof and explosion-proof performances. Background technique [0002] With the development of the economy, traffic accidents, robbery with a knife, school shootings and various risks that endanger personal safety also appear frequently. Therefore, the demand for protective equipment with puncture-proof and bullet-proof functions is gradually increasing. The existing protective equipment is composed of multi-layer high-strength fabrics, ceramic or metal materials and adhesive resins, wherein the high-strength fabrics mainly use aromatic polyamide fibers and ultra-high molecular weight polyethylene fibers. [0003] The density of aramid fiber is 1.45g / cm 3 And it has the characteristics of high tensile strength and high elastic modulus, but it has poor resistance to strong acid, strong alkali, ultraviolet light and...
