Abstract
The invention discloses a density gradient type armored protection device, which comprises an outer metal plate, an inner metal plate and a buffering layer, wherein the buffering layer is fixed between the outer metal plate and the inner metal plate. The buffering layer is formed by metal foam with density gradient changed, the outer metal plate is uniformly provided with holes with identical diameter, and chamfers are formed at outer edges of the holes. The weight of the density gradient type armored protection device can be reduced evidently by the aid of the holes and the density gradient foam layer, namely the buffering layer, and attacks of bullets/shrapnel and threats of explosion blast wave can be effectively resisted. Besides, the density gradient type armored protection device has double protection functions of resisting bullets and explosion blast.
Description
Technical field
The invention belongs to the armor facing technical field, particularly a kind of density gradient type lightweight compound sandwich protector.
Background technology
The armor facing technology is a most important component among the weaponry system survival ability.Any one modern weapons equipment all be unable to do without protection.Along with the antiarmor weapon technology rapid development; The battlefield survival of weaponry is to the demands for higher performance of armor facing structure, and good armor protection system can make the main body of tank, armored vehicle, armoured van and other structure and wherein personnel and property safety obtain better protection.Modern protection plate armour just develops towards the direction of Strengthening and Toughening, lightweight, modularization, multifunction and high performance." sandwich " structure is the armor facing structure of a quasi-representative, and panel can be selected steel, titanium alloy, aluminium alloy, composite etc., and the intermediate course material selected rubber, plastics, composite etc. more in the past.In recent years, along with technology of preparing improves, be that the appearance of the ultra light porous metal of architectural feature has realized structural material lightweight multifunction, thereby new selection be provided for the armor facing structure Design with millimeter level gap structure.
Summary of the invention
The object of the present invention is to provide a kind of density gradient type armor facing device, can significantly reduce the armoring weight of protection, and can effectively resist the impact of bullet/shell fragment and the destruction that the opposing explosion wave brings out.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of density gradient type armor facing device comprises outer metallic plate 1, interior metallic plate 6 and is fixed on the cushion between outer metallic plate 1 and the interior metallic plate 6, outside said, evenly offers porose 2 on the metallic plate 1.
The place, outer in said hole 2 is provided with chamfering.
The shape of cross section in said hole 2 is circle, ellipse, triangle or polygon.
The material of said outer metallic plate 1 and interior metallic plate 6 is armour steel, aluminium alloy, titanium alloy or depleted uranium alloy.
The material of said cushion is metal foam.
Said metal foam is foamed aluminium, foam aluminium alloy, foam copper or blister steel.
Said metal foam density changes in gradient, adopts shop layer order from low to high.
The material of said outer metallic plate 1 and interior metallic plate 6 is identical or different.
The thickness of said outer metallic plate 1 and interior metallic plate 6 is identical or different.
Said cushion comprises Low Density Metal Foam layer 3, middle density metal froth bed 4 and the high desnity metal froth bed 5 that ecto-entad sets gradually.
Fixed form between said outer metallic plate 1 and interior metallic plate 6 and the cushion is that welding or seccotine are bonding.
The present invention compares with prior art, has following advantage:
1,, thereby reduced the weight of protector of the present invention owing to evenly offer the hole 2 of certain density and same diameter on the metallic plate 1 outside;
2, because place, the outer in hole 2 is provided with chamfering; Can change the direction of motion of attacking bullet/shell fragment through the hole that has chamfering, reduce the speed of the bullet/shell fragment of high-speed motion, even it is ruptured; Become the slower fragment of some movement velocitys; Broken bullet/shell fragment embeds or when passing metal foam, the density gradient metal foam of filling has increased the path of shock motion, has reduced the surge of decling phase; Prolonged the action time of shock wave, thereby made the density gradient metal foam layers can further reduce the impact energy of bullet/shell fragment.Subsequently, interior metallic plate is done further interception to bullet/shell fragment, reduces the impact energy of bullet/shell fragment once more, stops by other external force more easily for the bullet/fragment of this motion state.Except the invasion and attack of the body/shell fragment that can effectively resist high-speed motion, the distortion that can also be through outer metallic plate 1 and interior metallic plate 6 and the collaborative realization of Low Density Metal Foam layer 3, middle density metal froth bed 4 and 5 conquassation of high desnity metal froth bed are to the buffering energy-absorbing of explosion wave.Thereby can effectively reduce or eliminate explosion wave to being reached wherein personnel's threat by the protection main body.
Therefore; Density gradient type metal foam sandwich armor facing device of the present invention can significantly reduce the weight of metal armor protector; 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.
