Description
Technical Field
The invention relates to the technical field of protective bulletproof equipment, in particular to a lightweight impact-resistant bionic bulletproof flashboard.
Background
Nowadays, weaponry is more and more advanced, and the killing power to the human body is also increased correspondingly. The body armor is used as protective equipment, and provides important guarantee for the life safety of individual soldiers. However, the prior bulletproof clothes have low bulletproof efficacy and cannot meet the expected protection requirement. In order to improve the bulletproof efficacy of bulletproof garments, bulletproof plugboards are increasingly widely used.
Most of the existing bulletproof flashboards are formed by compounding hard materials and flexible materials. The bulletproof flashboard has the defects of heavy overall weight, poor protective performance and large impact on human bodies. In the process of battle, the maneuverability and flexibility of individual battle can be influenced due to the overweight weight of the plugboard; meanwhile, even if the insert plate is not penetrated by the bullet, the impact force of the residual bullet still can cause certain damage to the human body and the visceral hemorrhage can be seriously caused, so that the good protection effect cannot be achieved.
Therefore, a bionic bulletproof flashboard which can reduce the weight of the flashboard and strengthen the impact resistance function of the bulletproof flashboard is needed.

Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings. As used herein, the terms "upper," "lower," "front," "back," and the like are used with reference to the orientation of FIG. 1.
The invention takes the head structure of a woodpecker as a biological prototype design. The woodpecker pecks the tree 500-600 times per day on average for foraging, and the impact speed is as high as 2000km/h when pecking the tree, so the head of the woodpecker is impacted greatly, but the woodpecker is still safe and has no brain concussion. This is closely related to the configuration of its head. The head bone is in a spongy shape, has a porous structure, is light in weight, and can effectively buffer the impact of external force. Meanwhile, compared with the human brain, the contact area between the brain and the skull of the woodpecker is relatively large, and the impact force can be better buffered and dissipated due to the structure. Therefore, the structure of the head of the woodpecker can be simulated, and the anti-bullet flashboard can be applied to the anti-bullet flashboard, so that the weight of the flashboard can be reduced, the anti-impact function of the anti-bullet flashboard can be enhanced, and the impact of bullets on human bodies can be reduced.
Example 1:
referring to fig. 1 to 3, a lightweight impact-resistant bionic bulletproof flashboard provided by an embodiment of the present invention includes an upper board 1, a middle board 2 and a lower board 3 stacked in sequence from top to bottom.
The upper plate 1 is a hard ceramic plate. The hard ceramic is one of alumina, boron carbide or silicon carbide. Among them, boron carbide has the best performance in all aspects, but the price of boron carbide is very expensive, and the price of silicon carbide is relatively moderate. And the density and hardness of the silicon carbide and the boron carbide are not greatly different, so the upper plate 1 in the embodiment is made of silicon carbide ceramic. The silicon carbide ceramic plate has very high strength, can be broken instantly when being impacted by a bullet, and attenuates the kinetic energy of the bullet by means of cracks generated by breaking. Silicon carbide ceramics are used as a rigid layer primarily to reduce the majority of the impact energy of the bullet.
The middle plate 2 and the lower plate 3 are made of the same material and are both high-performance fiber plates. The ultra-high molecular weight polyethylene (UHMWPE) has excellent service performance and moderate price. It has the comprehensive performance of impact resistance, impact energy absorption, sanitation, innocuity, wear resistance, corrosion resistance, adhesion resistance, water absorption resistance, low density and the like which are incomparable with common polyethylene and other engineering plastics. Therefore, the middle plate 2 and the lower plate 3 in the embodiment are both made of UHMWPE. The UHMWPE plate acts as a flexible layer to release energy.
The upper plate 1 is used as a rigid layer, the middle plate 2 and the lower plate 3 are used as flexible layers, the rigid layer and the flexible layers are compounded, so that the impact energy of the bullet can be dissipated in a short distance, the penetration depth of the bullet is reduced, and the injury to a human body is reduced.
The upper plate 1, the middle plate 2 and the lower plate 3 are connected by gluing, specifically, by a viscoelastic material. The adhesive is made of a viscoelastic material, so that impact energy can be absorbed easily. For example, the upper plate 1, the middle plate 2 and the lower plate 3 are connected by epoxy-phenolic adhesive. The adhesive is coated by a brush coating method, so that the thickness is ensured to be proper. By utilizing the characteristics of viscosity and elasticity of the viscoelastic material, the bionic bulletproof flashboard can absorb part of impact energy and delay the structural deformation.
The middle plate 2 is provided with a plurality of first through holes 5 in the thickness direction. The upper and lower sides of the first through-hole 5 are sealed by adhering the upper plate 1 and the lower plate 3 with a viscoelastic material, thereby forming a closed space. The first through hole 5 is filled with a plurality of small balls 4, and gaps exist among the small balls 4 and can move in the first through hole 5. Gaps exist between the small balls 4 and the wall of the first through hole 5, and the small balls 4 can move in the first through hole 5 conveniently. When the bulletproof flashboard without holes is impacted, the connection parts between the holes of the first through holes 5 are easy to generate compression deformation, so that the middle board 2 is deformed, external impact force is counteracted, and the harm to human bodies is reduced. Collision friction is generated between the plurality of small balls 4 and between the small balls 4 and the hole wall of the first through hole 5. The impact friction consumes the external impact energy, thereby generating the impact resistance effect. The vibration damping effect is different according to the shape, size, filling rate and material of the particles (i.e. the small balls 4). Through collision theory, the interrelationship between particles and structures can be obtained, and thus the consumed energy can be obtained.
In order to enhance the damping performance of the lower plate, the lower plate 3 is provided with a plurality of second through holes 6 along the length direction. When the bulletproof flashboard without holes is impacted, the connection parts between the holes of the second through holes 6 are easy to be compressed and deformed, so that the lower plate 3 is deformed, external impact force is counteracted, and the harm to a human body is reduced.
Further, the first through hole 5 has a cylindrical shape. The cylindrical through-hole is better in contact with the pellet 4 and therefore better adapted to the pellet 4. The diameter of the first through hole 5 should be much smaller than the caliber of the bullet, which can effectively prevent the bullet from passing through the board from the first through hole 5. The radius of the first through hole 5 is 0.1mm-0.5 mm. The first through holes 5 are arranged in a rectangular array, and the hole distance between every two adjacent first through holes 5 is 1-2 mm.
Furthermore, the radius of the small ball 4 is far smaller than that of the first through hole 5, at least 8 small balls 4 are arranged in the first through hole 5, and the radius of the small balls 4 is 0.01 mm.
Further, the end face size of the second through hole 6 has an important influence on the shock absorbing performance. According to the trace theory, when the solid structure is acted by external force, the distribution of the force in the object is along the direction of the trace, and the closer the distance between the solid structure and the trace is, the greater the stress in the area is. If a region of the structure has no traces, the stress in that region is very small or even close to zero. The material between the traces has no effect on resistance to deformation, will be in a waste state and then gradually disappear, but will not affect the strength of the entire structure. If the lower plate 3 is entirely solid in structure, it will easily carry the forces acting on it, but will increase in weight. In order to achieve a lightening of the bulletproof insert, it is necessary to reduce the weight as much as possible. The term porosity is used in this embodiment to refer to the percentage of the volume of pores in the bulk material relative to the total volume of the material in its natural state. The optimum porosity is also selected by balancing the maximum strength and the minimum weight of the bulletproof insert according to the maximum-minimum principle. Under the condition of certain porosity, the micro structure with single hole has better shock absorption and energy absorption effects on impact than the micro structure with a plurality of holes. Therefore, when the porosity is constant, the larger the second through hole 6 is, the better the vibration and energy absorption effects on impact are. But the second through-hole 6 must not be too large to prevent the passage of bullets directly through the second through-hole 6. But not too small, otherwise, the shock absorption and energy absorption effects on impact cannot be achieved. Therefore, the second through hole 6 has a rectangular parallelepiped shape with front and rear end faces being square, and the end face size of the second through hole 6 is 1mm × 1 mm. The plurality of second through holes 6 are arranged in a rectangular array, the distance between the left hole and the right hole of two adjacent second through holes 6 is 1mm-2mm, and the distance between the upper hole and the lower hole of two adjacent second through holes 6 is 1mm-2 mm.
Further, the upper surface of the middle plate 2 and the upper surface of the lower plate 3 are provided with wave-shaped convex structures. The wave-shaped bulge increases the contact area among the upper plate 1, the middle plate 2 and the lower plate 3, so that the plates are bonded more firmly and the dissipation of impact energy is facilitated. Of course, the wave-shaped bulges can be arranged on the upper surface of the middle plate 2 and the lower surface of the middle plate 2, and the effects can be achieved as well.
Further, upper plate 1, medium plate 2 and hypoplastron 3 all are the arc, can wear the protection picture peg better, have increased the area of contact of wearer with the protection picture peg, and the radian is 28 degrees for the selection of this embodiment, and upper plate 1, medium plate 2 and hypoplastron 3 sizes are 250mm x 300 mm.
Furthermore, chamfers are arranged on the left side and the right side of the same end part of the upper plate 1, the middle plate 2 and the lower plate 3 along the length direction, wherein the size of each chamfer is 10mm multiplied by 20mm, so that the corner positions of the bulletproof plugboard are uniformly transited, the bulletproof plugboard adapts to the requirements of bulletproof plugboards and bulletproof clothes, and the attractiveness and the practicability are improved. Of course, rounded chamfers may be provided.
Further, the thickness of the plate has a direct influence on the protective properties and the weight of the bulletproof insert plate. Upper plate 1, medium plate 2 and hypoplastron 3 are too thick, though be favorable to realizing high protectiveness, but can make whole protection picture peg become heavy, be unfavorable for the flexibility of individual soldier's operation. The upper plate 1, the middle plate 2 and the lower plate 3 are too thin, which is beneficial to the lightening of the whole protection plugboard, but can not achieve good protection effect. Therefore, the thicknesses of the upper plate 1, the middle plate 2 and the lower plate 3 are properly selected for the purpose of light weight and high bulletproof performance. Preferably, the thickness of the upper plate 1 is 8mm, the thickness of the middle plate 2 is 3mm, and the thickness of the lower plate 3 is 4 mm. At this time, the bulletproof insert plate had an overall thickness of 15mm and a mass of 1.2 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is penetrated, the middle board 2 is deformed, the lower board 3 is slightly broken, and the whole bulletproof flashboard is not penetrated.
Example 2:
the difference from example 1 was that the thickness of the upper plate 1 was 9mm, the thickness of the middle plate 2 was 5mm, and the thickness of the lower plate 3 was 5 mm. In this case, the bulletproof insert sheet had an overall thickness of 19mm and a mass of 1.36 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is penetrated, the middle board 2 is slightly deformed, the lower board 3 is not obviously changed, and the whole bulletproof flashboard is not penetrated.
Example 3:
the difference from example 1 was that the thickness of the upper plate 1 was 10mm, the thickness of the middle plate 2 was 4mm, and the thickness of the lower plate 3 was 6 mm. In this case, the bulletproof insert has an overall thickness of 20mm and a mass of 1.45 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is penetrated, the middle board 2 deforms obviously, the lower board 3 does not change obviously, and the bulletproof flashboard is not penetrated integrally.
Example 4:
the difference from example 1 was that the thickness of the upper plate 1 was 10mm, the thickness of the middle plate 2 was 6mm, and the thickness of the lower plate 3 was 7 mm. In this case, the bulletproof insert sheet had an overall thickness of 23mm and a mass of 1.7 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is penetrated, the middle board 2 is slightly deformed, the lower board 3 is not obviously changed, and the whole bulletproof flashboard is not penetrated.
Example 5:
the difference from example 1 was that the thickness of the upper plate 1 was 12mm, the thickness of the middle plate 2 was 6mm, and the thickness of the lower plate 3 was 7 mm. At this time, the whole thickness of the protective insert plate was 25mm, and the mass was 1.92 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is not penetrated, the middle board 2 is slightly deformed, and the lower board 3 has no obvious change. The bulletproof flashboard is not penetrated wholly
Comparative example 1:
the difference from example 1 was that the thickness of the upper plate 1 was 3mm, the thickness of the middle plate 2 was 2mm, and the thickness of the lower plate 3 was 3 mm. At this time, the entire thickness of the shield insert plate was 8mm, and the mass was 0.67 kg. When a bullet impacts the bulletproof inserting plate at the range of 10m away from the bulletproof inserting plate, the upper plate 1 of the bulletproof inserting plate is penetrated, the middle plate 2 is penetrated, the lower plate 3 is penetrated, and the whole bulletproof inserting plate is penetrated.
Comparative example 2:
the difference from example 1 was that the thickness of the upper plate 1 was 13mm, the thickness of the middle plate 2 was 7mm, and the thickness of the lower plate 3 was 10 mm. At this time, the entire thickness of the shield insert plate was 30mm, and the mass was 2.32 kg. When a bullet impacts the bulletproof flashboard at a range of 10m away from the bulletproof flashboard, the upper board 1 of the bulletproof flashboard is not penetrated, the middle board 2 is not obviously changed, and the lower board 3 is not obviously changed. The bulletproof flashboard is not penetrated in whole.
In conclusion, the thicknesses of the upper plate 1, the middle plate 2 and the lower plate 3 are too large, but the thicknesses do not penetrate through the upper plate, the middle plate and the lower plate, but the masses are too heavy, so that the light weight of the bulletproof flashboard cannot be achieved; the thicknesses of the upper plate 1, the middle plate 2 and the lower plate 3 are too small, so that although the light weight of the bulletproof flashboard is realized, the protection performance, namely the impact resistance, of the bulletproof flashboard cannot be ensured. For this purpose, the upper plate has a thickness in the range of 8mm to 12mm, the middle plate has a thickness in the range of 3mm to 6mm, and the lower plate has a thickness in the range of 4mm to 7 mm.
