Embodiment 1

[0049] (1) Unwind the ultra-high molecular weight polyethylene fiber 400D / 400F from the creel, and the unwinded fiber bundles pass through the warping machine and the DORNIER rigid rapier loom in turn, and weaving them to an areal density of 180g / m 2 woven plain weave, width 1.6m, length 200m.

[0050] (2) The woven plain weave fabric obtained in step (1) is subjected to 2KV corona treatment, and then glued through a dipping tank. The glue material is a polyurethane dispersion, and the glue content of the glued plain weave fabric is controlled by a pair of rollers. is 21.7%; then it is dried at 60°C through a hot tunnel, and finally wound by a winding device to obtain an areal density of 230g / m2 2 plain weave prepreg.

[0051] (3) The plain weave prepreg obtained in step (2) was hot-pressed and shaped at 130° C. and 0.6 MPa by a flat-panel laminator, and after cooling, the surface density was 230 g / m 2 Polyethylene bulletproof and stab-resistant material.

Embodiment 2

[0054] The manufacturing method provided in Example 1 is adopted, the difference is that: Aramid 800D / 1000F is used instead of ultra-high molecular weight polyethylene fiber 400D / 400F; the obtained area density is 240g / m 2 aramid ballistic and stab-resistant material.

[0055] Lay 23 layers of the aramid bullet-proof and stab-proof material provided in Example 2 so that the area density is 8.05kg / m 2 According to the GA68-2008 police stab-proof clothing standard, that is, with 24J±0.5J kinetic energy, effectively pierce at 0° and 45° penetration angles, and the knife tip is not allowed to penetrate the bullet-proof stab-proof clothing; according to GA141-2010 police body armor standard 3, that is, to prevent the 1951-style 7.62mm lead-core bullet fired by the 1979-style 7.62mm light submachine gun. The test results meet the requirements of ballistic and stab resistance.

Embodiment 3

[0057] The manufacturing method provided in Example 1 is adopted, the difference is: PBO fiber 1000D / 650F is used instead of ultra-high molecular weight polyethylene fiber 400D / 400F; the obtained area density is 230g / m 2 of PBO bulletproof and stab-proof material.

[0058] 23 layers of the PBO bulletproof and stab-proof material provided in Example 3 are laid up so that the area density is 8.05kg / m 2 According to the GA68-2008 police stab-proof clothing standard, that is, with 24J±0.5J kinetic energy, effectively pierce at 0° and 45° penetration angles, and the knife tip is not allowed to penetrate the bullet-proof stab-proof clothing; according to GA141-2010 police body armor standard 3, that is, to prevent the 1951-style 7.62mm lead-core bullet fired by the 1979-style 7.62mm light submachine gun. The test results meet the requirements of ballistic and stab resistance.

Abstract

The invention provides a method for manufacturing a bulletproof and stab-proof material, comprising the following steps: a) weaving high-strength fibers into a fabric; the strength of the high-strength fibers is ≥20cN / dtex, and the tensile modulus is ≥700cN / dtex; b ) The fabric obtained in step a) is subjected to surface treatment, dipping, drying and winding in turn to obtain a fabric prepreg; the glue used in the dipping process is a thermoplastic resin matrix; c) the fabric obtained in step b) is obtained The prepreg is hot-pressed and cooled to obtain a bullet-proof and stab-proof material. Compared with the prior art, the manufacturing method provided by the present invention uses high-strength fibers as raw materials, adopts specific process steps and conditions to achieve better interaction, and the obtained bullet-proof and stab-proof material has both excellent ballistic and stab-proof properties. , and lightweight and comfortable to wear. The experimental results show that the areal density of the bullet-proof and stab-proof material provided by the present invention is 240g / m 2 The following, and at the same time meet the requirements of bulletproof and stab-proof standards, and can be used as the basic material of bullet-proof and stab-proof products.

Description

technical field [0001] The invention relates to the technical field of bullet-proof and stab-proof materials, and more particularly, to a bullet-proof and stab-proof material and a manufacturing method thereof. Background technique [0002] The bulletproof fiber composite material is a resin-based composite material with fiber as the reinforcing material. It belongs to the high-strength fiber composite material. It has excellent physical and mechanical properties and good kinetic energy absorption performance, so it has good ballistic resistance. The manufacturing methods of high-strength fiber composite materials include the following two: weaving method and non-woven method. Among them, a unidirectional prepreg tape can be obtained by a nonwoven method. There are many kinds of high-strength fibers suitable for making unidirectional prepreg tapes. It is known that ultra-high molecular weight polyethylene (UHMWPE) fibers are suitable for making unidirectional prepreg tapes,...
