Embodiment 1

[0023] see figure 1 , the soft anti-stab and ballistic material of the present embodiment, from the outer layer (upper layer) to the inner layer (lower layer) sequentially includes: bulletproof fiber fabric layer 1, shear thickening liquid composite fiber fabric layer 2, thermoplastic resin composite fiber fabric layer 3 and shear thickening liquid syntactic foam layer4. There is no bonding between the four parts, and the layers can move relative to each other.

[0024] The bulletproof fiber fabric layer 1 is made up of at least one layer of aramid fiber (Kevlar) plain weave cloth, preferably 2-20 layers.

[0025] The fiber fabric layer 2 coated with the shear thickening liquid is composed of multiple layers of aramid fiber (Kevlar) plain weave cloth with a concentration of 10wt.% nano-silica shear thickening liquid, preferably 2-10 layers. The preparation of the composite fabric of the shear thickening liquid uses ethanol as the diluent to dilute the shear thickening liquid...

Embodiment 2

[0029] The main difference between this example and Example 1 is that the bulletproof fiber fabric layer 1 is formed by laminating and compounding 2-20 layers of fiber fabrics. , one or more of ultra-high molecular weight polyethylene fiber cloth (UHMWPE) and its UD, poly-p-phenylene benzobisoxazole fiber (PBO) fiber cloth and its UD, and high-performance nylon fiber cloth.

Embodiment 3

[0031] The difference between this example and Example 1 is mainly that the shear thickening liquid composite fiber fabric layer 2, wherein the fiber fabric is laminated and compounded by 21 layers of fiber fabric, the fiber fabric is selected from Kevlar fiber cloth, ultra-high molecular weight polyester One or more of vinyl fiber cloth, PBO fiber cloth, high-performance nylon fiber cloth.

Abstract

The invention discloses a soft stab-proof/bulletproof material, which comprises a bulletproof fabric layer (1), an STF (Shear Thickening Fluid) composite fabric layer (2) and a thermoplastic resin composite fabric layer (3) which are sequentially overlaid, wherein the bulletproof fabric layer (1) has excellent bulletproof performance; the shear thickening fluid (STF) has a special rheological characteristic and can absorb the quick impact energy; and the resin composite fabric can restrain the movement of fibers, and the destruction of the fabric mainly refers to fiber breakage, which can increase the consumption of the energy. By adopting overlaid bulletproof fabric, STF composite fabric and thermoplastic resin composite fabric layers, the soft stab-proof/bulletproof material of the invention is designed with different stab-proof/bulletproof composite structures, and has the advantages of realizing the complementary advantages of various materials, effectively ensuring the characteristics (include light weight, softness and comfortableness) of the protective materials and having excellent stab-proof/bulletproof performance.

Description

【Technical field】 [0001] The invention relates to a safety protection material, in particular to a stab-proof and bullet-proof material. 【Background technique】 [0002] The possibility of human beings facing various injuries in real life is increasing, and the types and performance requirements of protective equipment are also increasing. In the current era of peace, police officers and armed police officers and soldiers are far more likely to encounter danger than soldiers, and the danger they encounter not only comes from bullets, but also more and more from chopping and stabbing with knives and sharp objects Put on. [0003] The current flexible bulletproof clothing is mainly made of high-performance fiber fabrics. This bulletproof clothing can effectively prevent bullets, but the anti-stab and knife-cut effect is very poor. In order to improve the anti-stab and anti-ballistic performance, the usual measures are: adding metal plates or metal nets, increasing the number ...
