Problems solved by technology

Chinese patent CN201210364412 discloses a kind of anti-stab body which is made of polymer polyethylene and aramid fiber material by three-dimensional loom. Although the anti-stab body made of this material has good protection performance and soft comfort, The weaving efficiency of the three-dimensional loom is not high, and the cost of manufacturing is relatively high
Chinese patent CN201210084695 discloses a preparation method of shear thickening liquid / aramid fiber composite material, which realizes intelligent protection by compounding shear thickening liquid and aramid fiber material. This kind of protective body impregnated with shear thickening liquid is not easy Hold, the shear thickener will flow and affect the protection performance

preparation example Construction

[0040] like Figure 4 , the present invention also discloses a preparation method of a flexible anti-stab material arranged without gaps. The flexible anti-stab material arranged without gaps is composed of a flexible fabric 1 and several small protective modules 2 arranged on both sides of the flexible fabric. The fabric 1 and the small protective modules 2 on both sides are fixedly connected by an arrangement without gaps. The specific preparation method includes the following preparation steps:

[0041] S1, prepare the small protective module, and make the small protective module by injection molding or machining according to the preset parameters of the small protective module;

[0042] Among them, the small protective module made of thermoplastic reinforced composite material is made by injection molding; the small protective module made of metal is made by mechanical processing. The preset parameters of the small protective module include the shape, size and thickness of ...

Embodiment 1

[0051] In the flexible anti-stab material, the small protective module is made of carbon fiber staple fiber and thermoplastic nylon 66 composite reinforcement material through injection molding process, the mass fraction ratio of carbon fiber short fiber and nylon material is 1:3, and the side length of the small protective module is It is an equilateral triangle of 15mm, the thickness is 1.5mm, and the slope of the small protective module is 8°. as attached Figure 5 , 6 The lower mold has three rivets for riveting, and the small protective module of the upper mold has three through holes at the riveting position, and there are bayonet holes on the through holes. Figure 4 After the assembly is completed, the protruding rivets are flattened to the bayonet by heat welding to fix them firmly.

[0052] The flexible fabric sandwiched between the small protective modules is plain fabric made of aramid yarn, the weight of the fabric is 200 grams per square meter, and the gap betw...

Embodiment 2

[0055] In the flexible anti-stab material, the protective small module material that forms the protective material layer is made of high-strength aluminum alloy material, and the small protective module is made by machining. The specific size is a square with a side length of 20mm, a thickness of 1.5mm, and a thickness of The slope in the direction is 10°, such as image 3 After the two sides of the flexible fabric are aligned and overlapped, such as figure 1 Fastened by rivets. The flexible stab-proof fabric sandwiched in the middle can adopt the fabric made of nylon filament, and the fabric gram weight is 200 grams per square meter.

[0056] The quantity of the flexible protective material thus made is 1 protective layer, and the total mass of the protective layer of the cut-resistant clothing is 1.3kg, which can effectively protect against cutting and cutting injuries from sharp objects such as knives and glass.

Abstract

The invention discloses a flexible stab-resistant material arranged without gaps and a preparation method of the flexible stab-resistant material. The stab-resistant material comprises a flexible fabric and a plurality of small protecting modules fixedly arranged at two sides of the flexible fabric, wherein the plurality of small protecting modules are arranged without gaps in a certain way; the peripheral edge of each small protecting module is provided with a certain slope; the flexible fabric is made of a chemical fiber material or a high-strength and high-modulus material and is used for tightly connecting the small protecting modules at two sides; each small protecting module is made of a thermoplastic reinforced composite or a metal material. The invention also discloses a preparation method of the flexible stab-resistant material arranged without gaps. The flexible stab-resistant material arranged without gaps can be processed into various styles of stab-resistant body armors and protecting articles, the stab resistance of the stab-resistant material is improved, and meanwhile the flexibility of the stab-resistant material is also improved to the greatest extent.

Description

technical field [0001] The invention relates to a flexible anti-stab material and a preparation method thereof, in particular to a flexible anti-stab material arranged without gaps and a preparation method thereof. Background technique [0002] In recent years, terrorist attacks have continued to occur in various countries, and personnel from various countries have stepped up research and development in the field of security protection. In our country, with the development of social economy and the improvement of people's awareness of safety protection, the demand for safety protection equipment is increasing. The fourth key development area in the "Twelfth Five-Year Plan for Industrial Textiles" specifically mentions the development of flexible stab-resistant and cut-resistant fabrics, so the development of safety protection materials is in line with the development direction of the national textile industry, and flexible stab-resistant materials are used as a safety protec...
