Problems solved by technology

The anti-stab clothing made of high-performance fibers such as kevlar fiber, UHMPE fiber, etc. is called soft anti-stab clothing compared with traditional steel structure protection products. It has the characteristics of light weight and softness, but it requires multiple layers due to the protective effect. Fiber superposition is realized, and the protective layer generally requires as many as 40-50 layers. This structure is difficult to achieve flexible folding, so it is also not conducive to the actions of protective personnel.
At the same time, both of these two anti-stab materials are difficult to achieve comprehensive protection of the human body, especially the protection of joints, legs and other parts that require flexible movement, and the lack of blunt trauma to the human body due to poor energy absorption effect

Embodiment 1

[0022] A composite soft anti-stab material is prepared by using satin cloth woven with polyphenylene benzobisoxazole (PBO) fibers and 60 wt% (weight ratio) superfine silica shear thickening solution as raw materials. Firstly, dilute the nano silicon dioxide solution with ethanol as a diluent, and the approximate dilution ratio of ethanol:shear thickening liquid is 5:1 to 0.1:1. Then impregnate the PBO fiber cloth in the diluent, and at the same time carry out ultrasonic strengthening treatment on the impregnated system. Methods Ethanol was removed from the compounded material. This liquid composite material is used in a multi-layer stacking manner, as shown in Figure 1, to prepare a highly efficient stab-resistant composite structure, which is applied to different stab-resistant products. According to the standard GA68-2003 of the Ministry of Public Security, the puncture test of the material and structure was carried out, and it was found that compared with the PBO fiber clo...

Embodiment 2

[0024] Aramid fiber (Kevlar fiber) plain cloth and nano-titanium oxide shear thickening liquid with a concentration of 10wt% were used as raw materials to prepare soft stab-resistant materials. Use ethanol as the diluent to dilute the nano-shear thickening liquid, then impregnate the aramid fiber cloth in it, and at the same time perform high-frequency vibration treatment on the impregnated system, the vibration frequency is 1000-3000 Hz, and then vacuum desolventize the Ethanol is excluded to prepare aramid cloth liquid composite soft stab-proof material. Two kinds of materials, aramid cloth liquid composite anti-stab material 21 and aramid cloth 22, are used in a multi-layer superimposed manner, and the structures are respectively multi-layer aramid cloth and multi-layer liquid composite material from outside to inside, as shown in Fig. 2 Shown, compounded to prepare high-performance soft anti-stab products. According to the standard GA68-2003 of the Ministry of Public Secu...

Embodiment 3

[0026] The soft anti-stab material is prepared by using ultra-high molecular weight polyethylene fiber non-woven fabric and 40wt% nano-silica shear thickening liquid as raw materials. First, the ultra-high molecular weight polyethylene non-woven fabric is laid flat, and then the shear thickening liquid is coated on the non-woven fabric, and compacted to form an interlayer composite soft stab-proof material. Utilize this soft anti-stab material to form a multi-layered anti-stab composite structure, as shown in Figure 3, ultra-high molecular weight polyethylene non-woven fabric 31, shear thickening liquid interlayer composite anti-stab material 32, prepared Stab-resistant composite construction. According to the standard GA68-2003 of the Ministry of Public Security, the puncture test of the material and structure was carried out, and it was found that the liquid composite soft stab-proof material and the stab-proof composite structure have the characteristics of light weight, so...

Said invention also provides a soft body anti-pricking composite structure, said structure includes two layers or more than two layers laminated fiber fabric and liquor with shear thickening characteristics, said liquor with shear thickening characteristics is combined in the interior of one layer of said laminated fiber fabric or combined between two layers of said laminated fiber fabric.

Description

【Technical field】 [0001] The invention relates to a composite material and its application. 【Background technique】 [0002] With the advancement of science and technology, the possibility of human beings facing injuries in real life is increasing, and the requirements for the types and performance 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 most of the dangers they encounter come from chopping and piercing with knives and sharp objects, so stab-proof equipment is particularly important. [0003] At present, the commonly used stab-proof equipment mainly includes stab-proof clothing, neck guards and arm guards. Initially, stab-proof clothing was mainly made of hard steel plates, metal materials such as super-strength aluminum alloys, or hard non-metallic materials such as aluminum oxide and silicon carbide. This protective product ha...
