Description
Technical field
The invention belongs to technical field of armor protection, particularly a kind of glassy metal strengthens density gradient type lightweight compound sandwich protector.
Background technology
Armor facing technology is most important part among weapon system-of-systems survival ability.Any one modern weapons equipment all be unable to do without protection.Along with developing rapidly of antiarmor weapon technology; the performance of battlefield survival to armor facing structure of weaponry is had higher requirement, and excellent armor protection system can make the main body of tank and armored vehicle, armoured van and other structure and personnel wherein and property safety better be protected.Modern Protective armor is just towards the future development of Strengthening and Toughening, lightweight, modularization, multifunction and high performance." sandwich " structure is the armor facing structure of a quasi-representative, this structure is made up of two-layer panel and middle core, traditional panel can select steel, titanium alloy, aluminium alloy, composite etc., and intermediate sandwich material selected rubber, plastics, composite etc. more in the past.In the last few years, along with the raising of technology of preparing, effectively slab strength can be promoted by the glassy metal coating higher in metal decking surface spraying specific strength, and achieve structural material light multifunction with the appearance of the grade gap structure ultra light porous metal that is architectural feature, thus provide new selection for the design of armor facing structure.
Summary of the invention
A kind of glassy metal is the object of the present invention is to provide to strengthen Gradient-density armor protection device, significantly can reduce the weight of Protective armor, bullet/shell fragment that effective fragmentation is impacted, change the impact direction of bullet/shell fragment, and effectively absorb its impact energy, thus the possibility that reduction protector penetrates completely, play the impact resisting bullet/shell fragment and the effect of resisting the destruction that explosion wave brings out.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of glassy metal strengthens Gradient-density armor protection device, comprises outer metallic plate 1, interior metallic plate 6 and is fixed on the first cushion 3, second cushion 4 and three buffer layer 5 of the ecto-entad between outer metallic plate 1 and interior metallic plate 6; It is characterized in that: on described outer metallic plate 1, evenly offer the identical hole of diameter 2, and the outer surface of described outer metallic plate 1 is coated with glassy metal coating 7, the density of described first cushion 3, second cushion 4 and three buffer layer 5 changes in gradient.
The material of described glassy metal coating 7 is Fe-based amorphous alloy, zirconium-base amorphous alloy, cu-based amorphous alloys or cobalt base amorphous alloy.
The outer place in described hole 2 is provided with chamfering.
The shape of cross section in described hole 2 is circular, ellipse, triangle or polygon.
The material of described outer metallic plate 1 and interior metallic plate 6 is armour steel, aluminium alloy, titanium alloy or Depleted Uranium Alloys.
The material of described cushion is metal foam.
Described metal foam is foamed aluminium, foam aluminium alloy, foam copper or blister steel.
Described metal foam density changes in gradient, adopts ply stacking-sequence from high to low.
The material of described outer metallic plate 1 and interior metallic plate 6 is identical or different.
The thickness of described outer metallic plate 1 and interior metallic plate 6 is identical or different.
Described first cushion 3 is high desnity metal froth bed, and the second cushion 4 is Midst density metal foam layers, and three buffer layer 5 is Low Density Metal Foam layer.
Described glassy metal coating 7 adopts electric heating to excite and sprays on outer metallic plate 1.
Described outer metallic plate 1 and interior metallic plate 6 and the fixed form between cushion for weld or seccotine bonding.
Compared to the prior art, tool has the following advantages in the present invention:
1, owing to metallic plate 1 outside evenly offering the hole 2 of certain density and same diameter, thus the weight of protector of the present invention is reduced.
2, because metal sheet surface outside coats the very thin glassy metal coating 7 of one deck, this glassy metal coating has very high intensity, lower specific heat and is not very high fusing point, in bullet/shell fragment impact process, bullet/shell fragment can form higher surge, and cause higher temperature rise, thus easily make bullet/shell fragment be broken into panus, reduce the size of bullet/shell fragment, make to clash into the point load produced and become face load, thus the damage reduced structure, serve the effect of security protection.
3, because the outer place in hole 2 is provided with chamfering, the direction of motion of attacking bullet/shell fragment can be changed by the hole with chamfering, reduce the speed of the bullet/shell fragment of high-speed motion, it is even made to rupture, become the fragment that some movement velocitys are slower, when broken bullet/shell fragment embeds or passes metal foam, the density gradient metal foam of filling adds the path of shock motion, reduce the surge of decling phase, extend the action time of shock wave, thus make density gradient metal foam layers can reduce the impact energy of bullet/shell fragment further.Subsequently, interior metallic plate does further interception to bullet/shell fragment, again reduces the impact energy of bullet/shell fragment, and the bullet/fragment for this motion state is easier to stop by other external force.Except can effectively resist except the invasion and attack of body/shell fragment of high-speed motion, the cooperative achievement can also burst by the distortion of outer metallic plate 1 and interior metallic plate 6 and high desnity metal froth bed, Midst density metal foam layers and Low Density Metal Foam lamination is to the buffering energy-absorbing of explosion wave.Thus can effectively reduce or eliminate explosion wave to by the threat of protection main body and wherein personnel.
Therefore, glassy metal of the present invention strengthens the weight that density gradient type metal foam sandwich armor facing device significantly can reduce metal armor protector, bullet/shell fragment that effective fragmentation is impacted, change the direction of motion of bullet/shell fragment, reduce its movement velocity, and effectively absorb its impact energy, thus the possibility that reduction protector penetrates completely, play the effect of the destruction that the invasion and attack of resisting bullet/shell fragment and explosion wave bring out, there is the double protection function resisting body and blast impulse.
