Problems solved by technology

[0005] Compared with the GA68-2003 "stab-resistant clothing" standard of the Ministry of Public Security of the People's Republic of China, the knives used in the GA68-2008 standard are sharper, and the requirements for the puncture resistance of the stab-resistant materials are also higher. At the same time, the stab-resistant clothing currently on the market cannot meet the requirements of the new standard

preparation example Construction

[0026] The anti-stab composite material of the present invention can be prepared by conventional preparation methods in the field; the preparation method of the present invention can also be used, which includes the following steps: preparing raw materials—heating and dissolving—adding particles—gluing— Drying at room temperature - thermocompression molding. Specifically:

[0027] (1), prepare raw materials

[0028] Raw materials include fiber reinforcements, solid colloidal particles, solvents, and nanoscale oxide particles. Firstly, the fiber reinforcement is pretreated to make the cloth dense.

[0029] (2), heating and dissolving

[0030] Add solid colloidal particles with a weight percentage of 10%-30% to the solvent, and heat up until the colloidal particles are completely dissolved. The solvent is selected from one or more of methanol, ethanol, acetone, methyl ethyl ketone, cyclohexanone, dichloromethane, ethyl acetate, and butyl acetate.

[0031] (3), add particles ...

Abstract

The invention provides a thorn-proof composite material and a preparation method thereof. The thorn-proof composite material comprises a plurality of single-layer composite materials with micro holes, wherein each single-layer composite material comprises a reinforcing body formed by high-performance fibers, and a resin matrix which is compounded on the reinforcing body. The thorn-proof compositematerial further comprises a cushioning material for manufacturing a soft comfortable thorn-proof composite material.

Description

technical field [0001] The invention relates to a stab-resistant material, in particular to a stab-resistant fiber composite material with an improved structure and its application. Background technique [0002] At present, countries, especially China, have very strict control over firearms, so the threat from sharp weapons such as daggers is greater than the threat from bullets. In this sense, civilian stab-proof materials and cut-resistant materials are in greater demand than bullet-proof materials. [0003] The early anti-stab materials were cold-rolled high-performance alloys into overall-shaped anti-stab vests or high-strength and light-weight (such as aluminum alloy) metal materials to make the anti-stab layer like scale armor, although this anti-stab material is anti-puncture It has excellent permeability, but its quality and rigidity have great restrictions and influence on the user's activities and wearing comfort. Then in order to reduce the quality, the metal wi...
