Problems solved by technology

[0009] In summary, although there are currently research attempts on bionic camouflage materials, there are few applications of continuous fiber biomimetic structural fabrics for camouflage materials in high-strength and harsh environments.
And it has poor performance in radar wave camouflage, etc.

preparation example Construction

[0053] A method for preparing a directional-woven flexible camouflage composite material, comprising the following steps:

[0054] S1. Base fabric layer: Weave conductive and magnetic fibers and non-conductive fibers according to the warp and weft ratio of 3 to 10:1 to form a mesh cloth with a thickness of 0.5 to 3mm;

[0055] S2. Plant bionic body: Directly implant conductive fibers and non-conductive fibers on the grid cloth obtained in S1, and form plant bionic body on the base cloth layer;

[0056] S3. Infrared camouflage coating spraying: spray the infrared camouflage coating material on the surface of the finished product of S2, and dry and solidify;

[0057] S4. Visible light camouflage coating spraying: the visible light camouflage coating material is sprayed on the surface of the finished product of S3, and dried and cured.

[0058] Specifically: after the fiber fabric sprayed by S4 is dried at room temperature for 48 hours, it can be cut according to the required si...

Embodiment 1

[0064] It includes a base cloth layer 3 composed of mixed fibers, directionally woven conductive and magnetic fibers 2, and non-conductive fibers 3.

[0065] The preparation method of the material comprises the steps of:

[0066] S1: base fabric weaving

[0067] Such as figure 2 As shown, 6k nickel-plated carbon fiber and 4800Tex glass fiber are woven according to the warp and weft ratio of 5:1 to form a mesh cloth as shown in the figure, and the thickness of the fabric is about 1-2mm.

[0068] S2: Directional fabric weaving (i.e. plant bionics)

[0069] Press 12k nickel-plated carbon fiber cloth with 9600Tex glass fiber figure 1 , 2 The structure is oriented on the surface of the base fabric completed in S1, the arrangement interval is 2 mm, and the length of the oriented fabric is 20-30 mm.

[0070] S3: Infrared camouflage coating material spraying

[0071] The prepared infrared camouflage coating material is sprayed on the surface of the S2 finished product with a hi...

Embodiment 2

[0084] It includes a base cloth layer 3 composed of mixed fibers, directionally woven conductive and magnetic fibers 2, and non-conductive fibers 3.

[0085] The preparation method of the material comprises the steps of:

[0086] S1: base fabric weaving

[0087] Such as figure 2 As shown, 6k copper-plated carbon fiber and 1200D glass fiber are woven according to the warp and weft ratio of 4:1 to form a mesh cloth as shown in the figure, and the thickness of the fabric is about 0.5-1mm.

[0088] S2: Directional Fabric Weaving

[0089] Press 12k nickel-plated carbon fiber cloth with 2400D aramid fiber figure 1 , 2 The structure is oriented weaving on the surface of the base fabric completed in S1, the arrangement interval is 1 mm, and the length of the oriented fabric is 20-25 mm.

[0090] S3: Infrared camouflage coating material spraying

[0091] The prepared infrared camouflage coating material is sprayed on the surface of the S2 finished product with a high-pressure sp...

Abstract

The invention belongs to the field of functional fabrics, and relates to a directionally woven flexible camouflage composite material and a preparation method thereof. The directionally woven flexible camouflage composite material comprises a base cloth layer and a plant bionic body; the base cloth layer is formed by weaving electric and magnetic conductive fibers and non-conductive fibers; and the plant bionic body comprises a plurality of electric and magnetic conductive bionic bodies and non-conductor electric bionic bodies, and the plurality of electric and magnetic conductive bionic bodies and the non-conductor electric bionic bodies are directionally woven on the base cloth layer. Conductive carbon fibers and non-conductive fibers are woven in a mixed mode, and a bionic structure of a fabric base is constructed through directional weaving, so that the scattering function of radar waves is achieved; and meanwhile, infrared and visible light camouflage coating is sprayed on the surface of a fabric, so that the multi-spectrum camouflage function is achieved.

Description

technical field [0001] The invention belongs to the field of functional fabrics, and relates to a directional weaving flexible camouflage composite material and a preparation method thereof. Background technique [0002] With the proposal of China's maritime strategy, the importance of maritime rights and interests is increasing day by day, and more and more weapons and equipment are deployed in the southeastern coastal areas to ensure the security and stability of my country's southeastern coastal areas. However, the climate environment in the southeast coastal area is harsh, and it is located in a typical subtropical and tropical marine climate zone. High exposure, high temperature, high humidity and high salt fog are the main characteristics of the atmospheric environment in this area, so it is used for stealth, Camouflage materials face a severe test. [0003] At present, most of the camouflage net base materials used in the market are made of synthetic materials such a...
