Description

Technical Field

[0001] The utility model relates to the technical field of UD cloth, in particular to a stab-proof composite UD cloth. Background Art

[0002] UD cloth, also known as non-woven cloth, uses ultra-high-strength high-modulus polyethylene fiber as the base material. It is evenly laid with advanced high-tech equipment, impregnated with high-strength elastomer resin and bonded with film. It is the bulletproof material with the highest strength and lightest specific gravity.

[0003] The existing composite UD fabric has a structure of 90-degree orthogonal and 45-degree oblique. The composite method is to cut the 0-degree weft-free fabric, turn it 90 degrees or 45 degrees, and then place it on another 0-degree weft-free fabric to form a UD fabric roll with 0-degree continuous and 90-degree or 45-degree splicing. The composite UD fabric with a 90-degree orthogonal structure has a strong bulletproof effect, but poor stab-proof effect. The composite UD fabric with a 45-degree cross structure has a better stab-proof effect than the composite UD fabric with an orthogonal structure, but it is still not the best stab-proof angle.

[0004] To this end, the applicant provides a stab-proof composite UD fabric to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a stab-proof composite UD cloth, comprising a composite UD cloth made of a weftless cloth a and a weftless cloth b; in the composite UD cloth body, the fiber layer a in the weftless cloth a is against the fiber layer b in the weftless cloth b, the fiber angle of the weftless cloth a is 0 degrees, and the fiber angle of the weftless cloth b is 25 degrees to 40 degrees.

[0007] Furthermore, the main body of the non-woven fabric a is composed of a fiber layer a glued to a film a.

[0008] Furthermore, the main body of the non-woven fabric b is composed of a fiber layer b glued to a film b.

[0009] Furthermore, both the fiber layer a and the fiber layer b are ultra-high molecular weight polyethylene fibers.

[0010] Furthermore, the molecular weights of the fiber layer a and the fiber layer b are both 500,000 to 8,000,000.

[0011] Furthermore, both film a and film b are polyethylene blown films.

[0012] Furthermore, the composite temperature of the composite UD cloth is 100-130 degrees Celsius.

[0013] Furthermore, several pieces of composite UD fabrics can be composited again according to user needs.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a stab-proof composite UD fabric, which is interlaced with a non-weft fabric a and a non-weft fabric b.

[0024] like Figure 1-2 As shown, the present embodiment provides a stab-proof composite UD cloth, comprising a composite UD cloth 3 made of a non-weft cloth a1 and a non-weft cloth b2; in the composite UD cloth 3 body, the fiber layer a102 in the non-weft cloth a1 is against the fiber layer b202 in the non-weft cloth b2, the fiber angle of the non-weft cloth a1 is 0 degrees, and the fiber angle of the non-weft cloth b2 is 25 degrees to 40 degrees. The composite UD cloth is staggered by the non-weft cloth a and the non-weft cloth b, and the composite method is to cut the 0-degree non-weft cloth b and turn it 25 degrees to 40 degrees and then place it on the 0-degree non-weft cloth a, and the fiber layer a and the fiber layer b are in contact with each other. The non-weft cloth a and the non-weft cloth b are staggered and composited, which enhances the overall stab-proof effect.

[0025] In this embodiment, the main body of the non-weft fabric a1 is composed of a fiber layer a102 glued to a film a101.
