The monofilament diameter of aramid fiber is 30 microns, and the fiber density in the crack arrest layer is 1.45g / cm2; the monofilament diameter of nylon fiber is 20 microns, and the fiber density in the crack arrest layer is 1.26g / cm2.

[0095] The bomb layer is a high-hardness ceramic panel with a thickness of 7mm; the high-hardness ceramic panel has a strength of 3300MPa and a toughness of 3J / cm².

[0096] The basalt fiber / carbon fiber hybrid layer is a transition layer with a thickness of 2mm; in the basalt fiber composite material, the mixing ratio of basalt fiber and carbon fiber is 50% to 50%, the resin content is 30%, the tensile strength is 3000MPa, and the pr...

Example Embodiment

[0105] Experimental example 1

[0106] The test is carried out in the standard ballistic laboratory, the ammunition is kept at a constant temperature under standard temperature conditions for 2 hours, and the AVL Group B215 / B570 ballistic test system is used to determine the flying speed of the warhead.

[0107] The testing gun used in the test is a Type 56 7.62mm submachine gun, and the testing bullet used in the test is a Type 56 7.62mm ordinary steel core bullet.

[0108] The test sample is the basalt composite bulletproof board prepared in Example 1.

[0109] During the two inspections, the shooting distance is 15m, and the incident angle is 0°, which is perpendicular to the target. The results are as follows:

[0110] After the first shot, the speed of the warhead detected was 713m / s, the bulletproof plate was not penetrated, the diameter of the bullet wound on the front was 47mm, the depth of bullet wound was 14.5mm, the diameter of the bullet wound on the back of the bulletproo...

Abstract

The invention provides a basalt composite bulletproof plate which comprises a crack stopping layer, a bullet receiving layer, a transition layer and a back plate layer. The crack stopping layer is connected with a bullet receiving surface of the bullet receiving layer, so that a plate body of the bullet receiving layer is prevented from being cracked, and the bulletproof plate is prevented from being damaged for the second time; the bullet receiving layer bears and eliminates a bullet shooting impact force, so that a bullet body is damaged; the transition layer is clamped between the bullet receiving layer and the back plate layer, and is used for supporting the bullet receiving layer and reducing the stress between the bullet receiving layer and the back plate layer; and the back plate layer is connected with one surface, far away from the bullet receiving layer, of the transition plate, so that the cracked bullet body is stopped and is prevented from further penetrating. The bulletproof plate is high in hardness and thin, has no bulge, cannot hurt internal organs, and can effectively prevent bullet striking and disperse a bullet impact force.

Description

technical field [0001] The invention relates to a bulletproof product for safety protection, in particular to a basalt composite bulletproof board. Background technique [0002] With the advancement of science and technology, modern warfare has put forward higher and higher requirements for the protection of combatants. According to statistics, if bulletproof vests and helmets are used on the battlefield, the direct injuries to the head, chest and abdomen of the combatants can be reduced by 70-80%. In order to maximize the protection and combat capabilities of individual soldiers, all countries are actively developing bulletproof products. [0003] For bulletproof products, metal bulletproof, ceramic materials or high-tech fiber fabrics are often used as barrier materials in the prior art to absorb and alleviate the impact energy of bullets. [0004] However, in terms of the principle of bulletproof, metal bulletproof relies on plastic deformation to absorb the energy of b...
