The kind metal materials such as steel and titanium alloy are formed, although taking this structure that can promote safety and protectiveness to a certain extent
Can, but it bears a heavy burden big, and thickness is high, and tight ness rating is low, uses very not light, and materials consumption rate is big in the production process,
Cost is very high, it is difficult to form large-scale production.
For this purpose, entitled " a kind of novel light bulletproof composite structure " of No. 205300395U bulletin of Chinese patent provides one
Kind solution.The ballistic structure includes armour, buffer layer and backboard, wherein burster course and buffer layer, buffer layer and backboard
Between be bonded together by adhesive, and the ballistic fiber plate that burster course is 10-20mm thickness, buffer layer is thick for 6~8mm
Foamed aluminium board, backboard are then the aluminium sheet or steel plate of 1~4mm thickness.Although the ballistic structure simple production process, production efficiency are high,
Certain weight is reduced, and has taken into account lightweight and shellproof requirement, and high-low temperature resistant and anti-multiple blow performance are good, but it is tied
Structure tight ness rating is not high, and toughness and absorption kinetic energy effect are poor, and used fiberboard, aluminium sheet and steel plate not only enable the weight of mitigation
It is limited, also result in that production cost is higher, and the water-fast and moisture resistance properties it is difficult to ensure that very strong are bonded using adhesive, so as to
Use scope is enabled to be limited to, therefore, technique effect is up for further investigating.
Invention content
The purpose of this utility model is to solve to bear using the mode that toughness is strong and tight ness rating is high and anti-impact force effect is good
A kind of combined type ballistic-resistant assemble of the problems such as great enterprise low with tight ness rating and of high cost.
The combined type ballistic-resistant assemble that the utility model is proposed is respectively arranged with protection board including two layers and is arranged on two
Composite construction layer in protection board, the composite construction layer include having a shear thickening liquid for exuberant in it and being connected with each other
Hollow, rectangular part and the through-hole rectangular-shaped piece for being arranged on hollow, rectangular part edge.
Hollow, rectangular part in two layers of protection board above and below each is provided with 1-4, and through-hole rectangular-shaped piece is provided with
2-6.
The protection board is Kafra fiber structure, and the structure of forming composite structure layer is with super high molecular weight
Polytetrafluoroethylene material structure.
Four side of hollow, rectangular part is provided with gap, and the hollow, rectangular part and through-hole rectangular-shaped piece are by being bonded to each other and staggeredly
Arrangement form has the composite construction layer of Negative poisson's ratio.
The combined type ballistic-resistant assemble that the utility model is proposed is two layers protection board by setting respectively and is arranged on two
The exuberant hollow, rectangular for having shear thickening liquid and being connected with each other in composite construction layer and composite construction layer in a protection board
It part and is arranged on the through-hole rectangular-shaped piece of hollow, rectangular part edge dispersion is because of impact force caused by high velocity bullet or shrapnel rapidly, greatly
The big pressure reduced in structure, holding structure is tough, so as to be difficult to be pierced；Meanwhile for further more strength and enhance
Wearability and toughness using the protection board of Kafra fiber structure as external protection, have the polytetrafluoroethylene (PTFE) of super high molecular weight
Structure of the material structure as composite construction layer；In addition, in order to further be supported while lift structure tight ness rating
Impact force caused by anti-bullet or shrapnel, the hollow, rectangular part and through-hole rectangular-shaped piece to be formed by being bonded to each other and being staggered
Composite construction layer with Negative poisson's ratio, so as to which this combined type ballistic-resistant assemble be allow to have while safety is kept again
Have that flexibility is good, using it is light and of low cost the characteristics of, there is very high practicality and promotional value.
Description of the drawings：
Attached drawing 1 is the overall structure diagram of combined type ballistic-resistant assemble one embodiment that the utility model is proposed；
Attached drawing 2 is the inside concrete structure schematic diagram of composite construction layer；
Attached drawing 3 is the concrete structure schematic diagram of hollow, rectangular part；
Attached drawing 4 is the concrete structure schematic diagram of through-hole rectangular-shaped piece.
Specific embodiment：
Referring to Fig. 1 to Fig. 4, this four attached drawings provide combined type ballistic-resistant assemble one embodiment that the utility model is proposed
Appearance overall structure.The combined type ballistic-resistant assemble 1 is respectively arranged with protection board 2 including two layers and is arranged on two protection boards 2
Interior composite construction layer 3, the composite construction layer 3 include having shear thickening liquid for exuberant in it and being connected with each other hollow
Rectangular-shaped piece 31 and the through-hole rectangular-shaped piece 32 for being arranged on 31 edge of hollow, rectangular part, and in two layers of protection board 2 above and below each
The setting of hollow, rectangular part 31 there are three, may also set up 1-4, and there are four through-hole rectangular-shaped piece 32 then sets, may also set up
There are 2-6.
Shear thickening liquid is referred to as " liquid plate armour ", can mitigate heavy burden while with high intensity, belong to very
It is suitble to make the material of protection tool, in the structure of the bulletproof composite component, protection board 2 is used as external protection, composite construction
Layer 3 is then as inner protective layer, also, shear thickening liquid is exuberant in composite construction layer 3 and hollow, rectangular part 31 and is arranged on
The through-hole rectangular-shaped piece 32 of its edge is connected with each other, so as to make ballistic structure harder and tough, when by high velocity bullet or bullet
When piece impacts, the pressure in unit area can be reduced moment, impact force spreads out rapidly so that bullet or shrapnel are difficult to
Penetrate this structure.
The protection board 2 is Kafra fiber structure, and Kafra fiber is to be very suitable for shellproof material, utilizes Kev
Draw the protection board 2 of fibrous material being capable of lift structure compressive strength, enhancing wearability and flexibility and sealing as external protection
Property, so as to better against tear；And the structure of forming composite structure layer 3 is the polytetrafluoroethylene (PTFE) with super high molecular weight
Material structure, taking the polytetrafluoroethylene material of this kind of structure has extraordinary impact resistance and abrasion resistance properties, can be more preferable
Impact force caused by bullet or shrapnel is resisted on ground, so as to keep very strong crushing resistance and toughness.
31 4 side of hollow, rectangular part is provided with gap, and the hollow, rectangular part 31 and through-hole rectangular-shaped piece 32 are by mutually pasting
It closes and is staggered to form the composite construction layer 3 with Negative poisson's ratio.The composite construction layer 3 formed using this structure,
The structure can further be made to be offset by external force brute force attack to strength, enable it that there is very strong toughness and crushing resistance,
So as to resist strong impact power caused by bullet or shrapnel.
Therefore, this ballistic-resistant assemble anti-impact force significant effect, tight ness rating is high, and toughness is strong, can preferably absorb impact power
And tear is resisted, the pressure in unit area can be reduced rapidly, so as to which impact force be spread out, while is had again good
Wearability and water imbibition also save cost while reducing and bearing a heavy burden, have very positive technique effect.
