Abstract

The utility model relates to a bulletproof helmet defending automatic rifle and snipe rifle. The outer layer of the impact point connecting the bullet adopts bulletproof porcelain ball material. The inner layer adopts high molecule cloth or glass cloth material. The middle transitional layer adopts carbon cloth or aluminium alloy sheet material and the three different materials constitute a gradient complex structure bullet resistant material. Adopting the bulletproof porcelain ball as the basic material, with the round mechanical configuration, the kinetic energy can be effectively disassembled around and the bullet shear force is reduced from concentrating to one point to penetrate the helmet. Thus the protect effects is improved. The round structure of the bulletproof porcelain ball brings convenience to the helmet manufacture and maintenance.

Description

High-strength light porcelain based composites bulletproof halmet

Affiliated technical field: the utility model relates to a kind of human body security protection helmet.

Background technology: existing bulletproof halmet major part is divided into metal such as the armour plate punching press is made, and Heavy Weight can only be defendd 54 formula pistol cartridges usually, and protection level is low.A small amount of bulletproof halmet made from single kind macromolecular material is arranged at present, and size is thick, cost is high, also can only defend mini-submachine gun.In the face of the continuous upgrading of small arms, as coming into operation successively of semi-automatic rifle, automatic rifle, sniper rifle, original bulletproof halmet has been difficult to satisfy ballistic requirements, so Protection Product must be corresponding to its development." lance " arranged, " shield " need be arranged.

Summary of the invention: the utility model increases at automatic rifle, sniper rifle emission bullet kinetic energy, the situation that penetration capacity strengthens, and this product adopts new material and new structure to make the new helmet, resists the invasion and attack of bullet, guarantees human body head safety.

The technical scheme that its technical problem that solves the utility model adopts is: in order to improve ballistic performance, the nonmetallic materials of employing layer structure different performance or nonmetallic materials and metal material are compounded to form the gradient type composite and replace the armour plate material.Outer ceramic material---the shellproof porcelain ball that adopts of this bulletproof halmet, internal layer adopts macromolecular fibre cloth or glass fibre cloth material, and middle excessively layer adopts carbon cloth or aluminium alloy sheet material.The distribution of material of three kinds of unlike materials outside product, in, interior three layers, combine closely by adhesive, having formed has the gradient type of very strong ballistic performance composite.

The utility model is made into sphere with bulletproof ceramic, and it not only has the good mechanical performance, and easy to assembly.The shellproof porcelain ball of aluminium oxide, shellproof its proportion of porcelain ball of boron carbide are 1/2～1/3 of steel plates, can alleviate helmet weight so make the helmet with it respectively.The bulletproof ceramic protecting factor is much higher than armour plate.Bulletproof ceramic adopts on the spherical rather than tabular helmet that is suitable for use in very much certain radian, for making brings convenience.After resisting the bullet attack, if the porcelain ball is crashed to pieces, because the position that the porcelain ball accounts for is little, maintain and replace guarantees that bulletproof halmet can repeatedly use repeatedly very easily.Because bulletproof ceramic adopts chondritic, and good mechanical property has just been arranged, can reduce the bullet shearing force and concentrate, thereby improve protection effect effectively with kinetic energy decomposition around circle of point of impact to a certain point.

The utility model is hurted sb.'s feelings in order to prevent shellproof porcelain ball fragment, is stained with layer of non-woven fabric in helmet surface layer adhesive and makes to end broken layer.Simultaneously can conveniently spray paint for decoration thereon, increase aesthetic feeling.

The beneficial effects of the utility model are, guaranteeing that the helmet can defend automatic rifle, in the time of the sniper rifle invasion and attack, alleviate helmet weight as much as possible, are convenient to use.

Description of drawings:

The profile of Fig. 3, the utility model Fig. 2

Among Fig. 3: (1) nonwoven ends broken layer (skin-material);

(2) shellproof porcelain ball (cladding material)

(3) intermediate layer (middle transition layer material; Carbon cloth or aluminium alloy sheet);

(4) macromolecular fibre cloth (inner layer material)

The specific embodiment:

---top layer, intermediate layer---skin---operation construction that the making of the utility model product before had been ready to the helmet (inside and outside) mould, by shown in Figure 3, pressed internal layer.

By shown in Figure 3, shellproof porcelain ball is close to one by one, be in line, it is stand-by to paste the ball chain that forms the string shape with strip adhesive sticker paper tape;

By shown in Figure 1, when using aluminium alloy sheet, it is stand-by earlier it to be carried out preformed by helmet mould;

By shown in Figure 1, earlier with inner layer material---fiber cloth is put into the helmet internal mold that scribbles releasing agent after shearing by helmet size, the brushing adhesive stick connects between every two-layer fiber cloth, after being machined to certain thickness, coated with adhesive, then put into and shear the good excessive layer material in centre---carbon cloth or aluminum alloy thin (film) plate, sticking with glue agent between every two-layer carbon cloth or the aluminum alloy films connects, when middle transition zone is worked into certain thickness, coated with adhesive, the shellproof porcelain ball (as shown in Figure 3) of before having assembled bunchiness is stained with and throws off the adhesive sticker paper tape, after the porcelain ball evenly was covered with the whole helmet, adhesive on porcelain ball surface evenly sprays sticked layer of non-woven fabric again, cover the helmet external mold (tool) that scribbles releasing agent, in inciting somebody to action, outer mold is fixedly clamped, and treats in the mould that behind the adhesive solidification, die sinking is taken out goods and also sprayed the decoration lusterless paint,, treat that setting up frenulum after lacquer is done can check warehouse-in.

Claims

1, a kind of bulletproof halmet, constitute by multilayer material is compound, its technical characterictic is: the skin at contact bullet bullet adopts ball shape bulletproof ceramic, carbon cloth or aluminium alloy sheet are adopted in middle level excessively layer, internal layer adopts macromolecular fibre cloth or glass fabric, all connects compound formation integral body by adhesive between three layers.
