Description
Technical field
The utility model relates to a kind of flak jackets chip, especially a kind of flak jackets chip of Novel fixing structure.
Background technology
The traditional fabrication mode of flak jackets chip is by the fixed structure pattern gathering into folds without latitude cloth or woven fabric simple layer, in conjunction with anti-blunt wound layer, put into flak jackets overcoat, this preparation method is used in use procedure shellproof, between every layer of bulletproof cloth, can produce slippage, thereby generation frictional force, the ballistic performance of meeting infringement material after long-term dress is used.
And woven fabric is to be formed by the fibrage of warp-wise and broadwise, in woven process, the damage that the fiber of warp-wise is subject to is larger than broadwise, therefore in the time of the impact that is subject to bullet, there is the not good problem of longitude and latitude balance, the fiber of warp-wise and broadwise in the time transmitting the projectile energy of bullet, fibrous fracture imbalance, ballistic performance is not not fully exerted, and protective capacities is restricted.
And fixed by adhesive without the fiber of latitude cloth bullet resistant material different orientation, this kind of flak jackets is in the time being subject to bullet impact, bomb-release point discontinuity, and the energy power of outwards transmitting due to bomb-release point is not etc., thereby cause the delamination without latitude measuring fiber, it does not equally give full play of the bulletproof ability of fiber yet.
Utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of flak jackets chip of Novel fixing structure, this chip structure is simple, cost is low, adopt novel fixed form that bulletproof cloth (woven fabric or without latitude cloth) is fixed together effectively, increase the balance of woven fabric longitude and latitude, simultaneously with respect to the phenomenon that also can reduce delamination without latitude cloth, the ballistic performance of fiber is brought into play, greatly improve the protective capacities of bulletproof cloth, and this fixed form has also increased the stability of flak jackets chip, contribute to reduce the friction between bullet resistant material, extend service life.
For realizing above-mentioned object, the technical solution of the utility model is:
A flak jackets chip for Novel fixing structure, comprising: superficial density is at 100-500g/m
2between bulletproof cloth, 10-80 layer bulletproof cloth is stacked together, bulletproof cloth adopts every 3-20 centimetre of syndeton mode of adding a sewing thread and fixes, uniform multilayer bulletproof cloth unit trellis is fixed together, and the sewing angle of sewing thread keeps being 0-90 degree angle with bulletproof cloth fiber and sews fixing.The sub-box of square, rectangle or rhombus that after sewing, sewing thread composition size is equal, the way of this blocking increased flak jackets chip stability, reduced the friction between bullet resistant material, flak jackets chip can be fixed with sewing thread completely, also can only fix with sewing thread in the shellproof part of key.
Described sewing thread is the one in nylon, aramid fiber or cotton thread.
The number of plies of described bulletproof cloth is 45 layers, and the design of this kind of number of plies can ensure the highest cost performance and higher degree of protection.
Described bulletproof cloth is woven fabric or without the one in latitude cloth,, high modulus fiber high-strength by aramid fiber, high-performance polyethylene fibres, carbon fiber etc. is made.
The superficial density of described bulletproof cloth is 300g/m
2, the cost performance of this kind of superficial density is the highest, and degree of protection is better.
Show through experiment test: after being both the aramid fiber woven fabric (simple layer gathers into folds) of 24 layers and adopting a kind of novel fixed knot of the present utility model to be fixed the aramid fiber woven fabric of 24 layers, the V50 value of same test 1.1g fragmentation, result shows, the flak jackets of making by fixed form of the present utility model, the flak jackets 50m/s of the same shellproof number of plies that the V50 value of anti-1.1g fragmentation gathers into folds higher than traditional simple layer.
Effect intentionally of the present utility model is: this chip structure is simple, cost is low; increase the balance of woven fabric longitude and latitude; simultaneously with respect to the phenomenon that also can reduce delamination without latitude cloth; the ballistic performance of fiber is brought into play; greatly improve the protective capacities of bulletproof cloth; and this fixed form also increased flak jackets chip stability, contribute to reduce friction between bullet resistant material, extended service life, life security that can more effective protection user of service.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is elaborated.
By shown in Fig. 1 to Fig. 3, a kind of flak jackets chip of Novel fixing structure, comprising: superficial density is at 100-500g/m
2between bulletproof cloth 101, 10-80 layer bulletproof cloth 101 is stacked together, bulletproof cloth 101 adds a sewing thread 102 every 3-20 centimetre, with this, multilayer bulletproof cloth 101 uniform unit trellis are fixed together, the sewing angle of sewing thread 102 keeps being 0-90 degree angle with bulletproof cloth 101 fibers and sews, after sewing, sewing thread 102 forms the square that size is equal, the sub-box of rectangle or rhombus, the way of this blocking has increased the stability of flak jackets chip, reduce the friction between bullet resistant material, flak jackets chip can be completely fixing with sewing thread 102, also can be only fixing with sewing thread 102 in the shellproof part of key.
Described sewing thread 102 is the one in nylon, aramid fiber or cotton thread.
The number of plies of described bulletproof cloth 101 is 45 layers, and the design of this kind of number of plies can ensure the highest cost performance and higher degree of protection.
