Embodiment 1

[0032] Such as Figure 1-3 As shown in the figure, a bionic bullet-proof board that can change the direction of the warhead includes an upper board 1 made of hard ceramics and a lower board 2 made of high-performance fibers;

[0033] In this embodiment, the dimensions of the upper plate 1 and the lower plate 2 are both 250mm*300mm, and the material of the upper plate 1 is hard ceramics, and the hard ceramics are aluminum oxide, boron carbide or silicon carbide. One, wherein boron carbide has the best performance in all aspects, but the price of boron carbide is very expensive, while the price of silicon carbide is relatively moderate, and its density and hardness are not much different from boron carbide, so the upper layer in this embodiment adopts Made of silicon carbide ceramics. The strength of the silicon carbide ceramic plate is very large, and it will be broken instantly when it is hit by a bullet. It relies on the cracks generated by the fragmentation to disperse the ...

Embodiment 2

[0050] The shape of the first convex hull 3 is a hemisphere, the side of the upper plate 1 away from the lower plate 2 is the upper surface, and the radius of the first convex hull 3 is 4mm; the upper surface of the upper plate 1 The first convex hull 3 changes the angle of incidence of bullets injected into the bulletproof plate, reducing the impact of bullets on the plate. The size of the first convex hull 3 has a direct impact on the angle of incidence of the bullet. The first convex hull 3 is too large or too small relative to the caliber of the bullet, which is not conducive to the direction change of the bullet. Multiple first convex hulls 3 are arranged in a rectangular array. , the gap between adjacent first convex hulls 3 is 2 mm; the gap between adjacent first convex hulls 3 should be smaller than the caliber of bullets, which can effectively prevent bullets from entering the board from the gap.

[0051] Wherein, the second convex hull 14 is a one-third sphere, and t...

Embodiment 3

[0054] The shape of the first convex hull 3 is a hemisphere, the side of the upper plate 1 away from the lower plate 2 is the upper surface, and the radius of the first convex hull 3 is 6 mm; the upper surface of the upper plate 1 The first convex hull 3 changes the angle of incidence of bullets injected into the bulletproof plate, reducing the impact of bullets on the plate. The size of the first convex hull 3 has a direct impact on the angle of incidence of the bullet. The first convex hull 3 is too large or too small relative to the caliber of the bullet, which is not conducive to the direction change of the bullet. Multiple first convex hulls 3 are arranged in a rectangular array. , the gap between adjacent first convex hulls 3 is 2 mm; the gap between adjacent first convex hulls 3 should be smaller than the caliber of bullets, which can effectively prevent bullets from entering the board from the gap.

[0055] Wherein, the second convex hull 14 is one-third of a sphere, a...

Abstract

The invention belongs to the technical field of protective bulletproof equipment treatment, and particularly relates to a bionic bulletproof insert plate capable of changing the direction of a bullet.The bionic bulletproof insert plate capable of changing the direction of the bullet comprises an upper board made of hard ceramics and a lower board made of high-performance fibers, wherein the upperplate and the lower plate are fixedly arranged together. A plurality of first convex hulls are arranged on the side, away from the lower plate, of the upper plate at equal intervals, the upper plateis mainly used for reducing most impact energy of the bullet, the lower plate plays a role in slowly releasing energy, and meanwhile, the form of the first convex hulls of the upper plate changes theshoot angle of the bullet shot into the bulletproof insert plate; and grooves in a first layer of the upper plate and second convex hull structures in a second layer are connected together in a clamped mode, the shoot angle of the bullet shot into the bulletproof insert plate is further changed, and the impact force of the bullet invading into the vertical direction of the insert plate is reduced,so that the upper plate of the insert plate is more beneficial to reducing the impact force and speed when the bullet collide with the bulletproof insert plate, dissipation of impact energy is facilitated, and therefore the penetration depth of the bullet on the bulletproof insert plate is reduced.

Description

technical field [0001] The invention belongs to the technical field of protective bulletproof equipment, and in particular relates to a bionic bulletproof plate capable of changing the direction of a warhead. Background technique [0002] As a kind of protective equipment, the bulletproof plate provides an important guarantee for the life safety of individual soldiers. In order to improve the protection level of bulletproof vests, the application of bulletproof inserts is more and more extensive. The rapid development of weapons and equipment has gradually increased the threat to the life safety of individual soldiers. In order to ensure the safety of individual soldiers and improve the flexibility of individual combat, it is necessary to develop light-weight and high-efficiency bulletproof equipment. [0003] At present, the bulletproof inserts are mostly made of high-hardness bulletproof ceramics and high-toughness fiber composite materials. Such bulletproof inserts have...
