Description
Technical Field
The utility model relates to the technical field of bulletproof plugboards, in particular to a multi-curved-surface composite bulletproof plugboard.

The bulletproof flashboard is mainly applied to the field of individual protection, is usually used as a 'fitting' of bulletproof clothes, is inserted in front of the bulletproof clothes, and is used together with the bulletproof clothes to achieve the required protection level, so that the impact of high-speed bullets on important organs of a trunk is reduced.
For high-elastic-speed weapons such as rifles and submachine guns, the composite bulletproof flashboard is the first choice equipment for military use and police use due to high cost performance. The bulletproof flashboard is added into the bulletproof vest, so that the defect that the defense performance of a soft bulletproof layer of the bulletproof vest is weak can be greatly overcome, the death rate of soldiers on a battlefield is greatly reduced, the overall fighting capacity of troops is improved, and compared with flashboards made of other materials, the composite bulletproof flashboard is lighter in weight and more beneficial to military and police personnel to improve tactical flexibility.
At present, most of the composite methods of the composite bulletproof flashboards at home and abroad adopt small ceramic plates with different shapes to be directly bonded to the single-curved-surface composite flashboard. However, regardless of the type of composite ballistic panel described above, the resistance to falling is extremely poor and the ceramic is subject to cracking.
In patent CN202120997870.6, a multi-curved surface composite ceramic bulletproof insert plate is disclosed, which comprises a crack-stop layer, a ceramic layer, a transition layer and a support layer, which are sequentially stacked, and two adjacent layers are adhered through a sandwiched hot melt adhesive film; the whole outer surface is also sprayed with a polyurea coating. The anti-cracking insert plate is compounded by adopting a crack stop layer and a transition layer of aramid woven fabric, a boron carbide ceramic layer and a PE supporting layer, so that the light weight and high performance requirements of the anti-cracking insert plate are met; the multiple bullet resistance of the bulletproof flashboard is enhanced, and the bulletproof requirement under the environment of normal temperature, high temperature, low temperature and salinization is met; the integral outer surface is sprayed with a polyurea coating, so that the weather resistance, the wear resistance and the waterproof and anti-falling capacity of the inserting plate are improved; the human engineering modeling design with multiple curved surfaces is adopted, so that the human engineering modeling is more easily attached to the part of the human body needing to be protected. Although the patent is light in weight and can prevent bullets from penetrating, the impact force on human bodies is still large, and the protection capability is insufficient.
In patent CN200810161474.9, an antiballistic shaped part is disclosed, comprising at least two barrier layers and a buffer layer between the barrier layers, wherein the barrier layers and the buffer layer comprise a plurality of superimposed weftless fabrics, the weftless fabrics comprise fibers with a strength of at least 15CN/dtex and a modulus of at least 390CN/dtex, an angle formed by the fibers in adjacent weftless fabrics in the buffer layer is 40 to 60 degrees, and an angle formed by the fibers in adjacent weftless fabrics in the barrier layers is 85 to 95 degrees. The patent also provides a method for producing an antiballistic shaped part. The barrier layer has high strength, so that the bullet speed can be effectively reduced, the buffer layer tends to have an isotropic effect, so that kinetic energy of a bullet can be absorbed and diffused, the bulletproof formed part provided by the patent has a good bulletproof effect under the alternate effect of the barrier layer and the buffer layer, and can protect a wearer from being injured by the bullet as a bulletproof helmet or bulletproof clothes, but the effect of preventing penetration of the bullet is poor.
In patent No. cn201811571780.x, a composite body armor is disclosed, comprising, from outside to inside, a ballistic layer, a protective layer, a buffer layer and an energy absorbing layer; the bullet absorbing layer is used for absorbing bullets to avoid the generation of a flowing bullet and comprises two carbon fiber layers and an aluminum foam layer, wherein the aluminum foam layer is sandwiched between the two carbon fiber layers; the buffer layer is used for converting point impact into surface impact; the absorption layer is used for absorbing the deformation of the buffer layer. The patent can effectively avoid the generation of the fluid bombs and the danger of rib fracture of the fighter caused by excessive impact force, but the capability of resisting deformation is poor.
