Description

Technical Field

[0001] The present invention belongs to the technical field of protective arrays and also to the technical field of protective materials, and specifically relates to a stab-proof protective array structure and a preparation method thereof. Background Art

[0002] As mentioned in the prior art solution with patent publication number "CN111719320A", the existing protective materials mostly adopt a single structure, such as a single stab-proof layer or a cut-proof layer. These materials have certain protective effects in specific situations, but in complex situations, protective materials with a single structure are difficult to cope with changing threats. In order to improve the protective performance, flexibility and breathability are often ignored, making the wearer bulky and inflexible, thereby reducing the protective performance. We are forced to choose multi-layer composite fabrics with poor breathability, stiff texture, and extremely uncomfortable finished products as alternative products.

[0003] The current protective fabrics include the following:

[0004] 1. There is no protective array designed on the surface of the protective fabric. It only improves the protective performance by simply mechanically stacking multiple layers of fabric to increase the thickness of the overall fabric. This kind of fabric has poor flexibility, is not breathable, and has poor protective performance.

[0005] 2. The protective array designed on the surface of the protective fabric is a simple geometry, such as polygons, circles, etc. This type of protective fabric improves flexibility and breathability, but the protective performance is not improved much and cannot meet international standards. Summary of the invention

[0006] In order to solve the defects in the prior art, the present invention proposes a stab-proof protective array structure and method, which not only provides excellent stab-proof and cut-proof performance, but also improves the flexibility and comfort of the protective material through bionic design. Finally, a protective array shape that can be applied to stab-proof and cut-proof, comfortable and breathable composite fabrics is designed. Combining the protective performance and comfort of the fabric, the selection of fabric no longer requires a choice between protection and comfort, but both can be taken into account, and the protective performance is greatly improved, which can fully meet international standards.

[0007] The present invention uses the following technical solutions.

[0008] A method for preparing a stab-proof protective array structure, comprising:

[0009] S1. Constructing a bionic structure of a stab-proof protective array structure;

[0010] S2. construct a full coverage structure of the stab-proof protection array structure;

[0011] S3. Staggeringly connecting the bionic structure of the stab-proof protection array structure and the full-coverage structure of the stab-proof protection array structure to prepare the stab-proof protection array structure.

[0012] Furthermore, in S1, the method for constructing a bionic structure of a stab-proof protective array structure includes: imitating the skin-bone array structure of crocodile skin to construct a protective array with similar natural protective properties.

[0013] Further, in S1, the method of constructing a protective array having similar natural protective properties by imitating the skin-bone array structure of crocodile skin specifically includes:

[0014] Use a right triangular prism to perform the deformation:

[0015] The base triangle of the right triangular prism is constructed as an isosceles right triangle, and the side quadrilateral is constructed as a rectangle; then select the side surface containing the hypotenuse of the base triangle and bend the side surface inward.

[0016] Further, in S1, the hypotenuse of the isosceles right triangle is 3.1 mm.

[0017] Furthermore, in S1 , the length of the rectangle is 4.5 mm.

[0018] Furthermore, in S1, the right triangular prism may be replaced by a regular triangular prism or a regular quadrangular prism.

[0019] Further, in S2, the method for constructing the full coverage structure of the stab-proof protection array structure includes: using regular hexagonal prisms to construct:

[0020] The side length of the regular hexagon of the regular hexagonal prism is 1.5 mm, the thickness is 0.5 mm, and the gap between adjacent regular hexagons is controlled to be 0.5 mm.

[0021] Further, in S2, the regular hexagonal prism may be replaced by a regular pentagonal prism.

[0022] Further, in S3, the method of staggered connection of the bionic structure of the stab-proof protection array structure and the full-coverage structure of the stab-proof protection array structure comprises: aligning a vertex angle of the curved side surface of the straight triangular prism and a side edge of the adjacent prism with one of the vertex angles of the upper surface of the regular hexagonal prism below and a side edge of the adjacent hexagon for compounding.

[0023] A stab-proof protection array structure, comprising:

[0024] The bionic structure of the stab-proof protection array structure and the full coverage structure of the stab-proof protection array structure in which the bionic structure of the stab-proof protection array structure is staggered and connected according to multi-layer regular staggering.

[0025] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:

[0026] The bionic structure and the full-cover structure are specially shaped to produce a special geometric energy absorption effect, which improves its protective ability. A certain gap is maintained between the protective arrays to meet the bending deformation, thereby maintaining the overall softness without affecting its protective performance. At the same time, a layer of protective resin under the bionic structure can effectively improve the bending stiffness of the bionic structure and enhance the bionic structure's ability to resist deformation.
