Abstract
The invention discloses a novel light composite sandwich protection device which comprises an outer metal plate, an inner metal plate and a buffer layer fixed between the outer metal layer and the inner metal layer, wherein holes are uniformly formed on the outer metal plate; and a chamfer is arranged on the outer edge of each hole. The device disclosed by the invention can be used for obviously reducing the weight of metal armor protection, effectively resisting the attack of bullet/shrapnel as well as the threat of shock wave, and realizing double protection functions of resisting bullet and explosion.
Description
Technical field
The invention belongs to the armor facing technical field, particularly a kind of novel light compound sandwich protector.
Background technology
The armor facing technology is most important part among the weaponry system survivability.Any one modern weapons equipment all be unable to do without protection.Good armor protection system can so that the main body of tank, panzer, armoured van and other structure and wherein personnel and property safety better protected.Armor facing has polytype, and comparatively advanced unit is " sandwich " structure at present, is comprised of two panels and an intermediate sandwich material.Panel can be selected steel, titanium alloy, aluminium alloy, composite etc., and intermediate sandwich material can be selected rubber, plastics, metal foam etc., and for example: panel is that the aluminum foam sandwich that the metal foamed aluminium sandwich is armoring, panel is composite of steel plate is armoring.This class armor facing absorbs blast by malformation and attacks the impact energy of bullet/shell fragment, but its weight is larger, and resists the limited in one's ability of bullet/shell fragment, and the safeguard structure of exploring lightweight and possessing the high efficient protected performance is the ultimate aim of armor facing.
Summary of the invention
The shortcoming that exists in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of novel light compound sandwich protector, the weight of Protective armor be can significantly reduce, and the impact of bullet/shell fragment and the destruction that the opposing explosion wave brings out are highly resistant to.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of novel light compound sandwich protector comprises outer metallic plate 1, interior metallic plate 2 and is fixed on cushion 3 between outer metallic plate 1 and the interior metallic plate 2, evenly offers porose 4 on described outer metallic plate 1.
The place, outer in described hole 4 is provided with chamfering.
The shape of cross section in described hole 4 is circle, ellipse, triangle or polygon.
The material of described outer metallic plate 1 and interior metallic plate 2 is armour steel, aluminium alloy, titanium alloy or Depleted Uranium Alloys.
The material of described cushion 3 is metal foam.
Described metal foam is foamed aluminium, foam aluminium alloy, foam copper or blister steel.
The material of described outer metallic plate 1 and interior metallic plate 2 is identical or different.
The thickness of described outer metallic plate 1 and interior metallic plate 2 is identical or different.
Fixed form between described outer metallic plate 1 and interior metallic plate 2 and the cushion 3 is that welding or seccotine are bonding.
The present invention is compared with existing technology, and has following advantage:
1, owing to evenly offering the hole 4 of certain density and certain size on the metallic plate 1 outside, thereby reduced the weight of protector of the present invention;
2, because place, the outer in hole 4 is provided with chamfering, can change to attack by the hole with chamfering the direction of motion of bullet/shell fragment, reduce the speed of the bullet/shell fragment of high-speed motion, even make its fracture, become the slower fragment of some movement velocitys, broken bullet/shell fragment embeds or passes metal foam, further consume the impact energy of bullet/shell fragment, subsequently, interior metallic plate is done further interception to bullet/shell fragment, again reduce the impact energy of bullet/shell fragment, stop by other external force for the bullet/fragment of this motion state is easier.Except the invasion and attack of the body/shell fragment that can effectively resist high-speed motion, distortion that can also be by outer metallic plate 1 and interior metallic plate 2 and the collaborative realization of metal foam 3 conquassation be to the buffering energy-absorbing of explosion wave, thereby can effectively reduce or eliminate explosion wave to by protection main body and wherein personnel's threat.
Therefore, novel light compound sandwich protector of the present invention can significantly reduce the weight of metal armor protection, it can resist the threat of explosion wave effectively simultaneously in the invasion and attack that can effectively resist bullet/shell fragment, has the double protection function of resisting body and blast impulse.
Description of drawings
Fig. 1 is structure cross-sectional schematic of the present invention.
Fig. 2 is schematic top plan view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of novel light compound sandwich of the present invention protector, comprise that outer metallic plate 1, interior metallic plate 2 and welding or seccotine are bonded in the cushion 3 between outer metallic plate 1 and the interior metallic plate 2, on described outer metallic plate 1, evenly offer porose 4.
Preferably, place, the outer in described hole 4 is provided with chamfering.
The shape of cross section in described hole 4 can have any shape, and such as circular, ellipse, triangle or polygon, as shown in Figure 2, is preferably circle, is convenient to processing.
The material of described outer metallic plate 1 and interior metallic plate 2 is metal, such as armour steel, aluminium alloy, titanium alloy or Depleted Uranium Alloys etc.
The material of described cushion 3 is metal foam, is preferably foamed aluminium, foam aluminium alloy, foam copper or blister steel.
The material of described outer metallic plate 1 and interior metallic plate 2 is identical or different.
The thickness of described outer metallic plate 1 and interior metallic plate 2 can be the same or different.
