Abstract
The invention discloses a novel liquid bulletproof garment, which comprises a bulletproof garment body. The bulletproof garment body is prepared by Kevlar fiber which is soaked by STF (shear thickening fluid) liquid. The novel liquid bulletproof garment disclosed by the invention fully uses the advantages of the Kevlar fiber such as light weight, high intensity, heat resistance, cut resistance and the like; and the bulletproof garment in combination of the STF liquid has a faster reaction speed, and a shallower depth of impact points. The novel liquid bulletproof garment is combined with the traditional Kevlar fiber bulletproof garment, so that the fighting flexibility of soldiers can be enhanced; and the thickness of the bulletproof garment can be reduced by more than 45%. Through detection, the performances of the combination of 10 layers of Kevlar fiber and the shear thickening fluid are better than the performances of 30 layers of unprocessed Kevlar fiber.
Description
Technical field
The present invention relates to a kind of military flak jackets, particularly a kind of new liquid flak jackets belongs to military, the alert protective gear technical field of using.
Background technology
Flak jackets is to invent after the World War II.Be divided into three kinds according to the unusual of material therefor: first kind is rigid flak jackets, is to be processed by steel plate, steel wire or ceramic wafer, and its principle is " firm with firm gram "; Heavily about 10-20 kilogram; Very heavy, therefore to wear uncomfortablely, action is inconvenient; And can not protect whole body (can not get effective protection), irremediable shortcoming is arranged like neck etc.Second kind is soft flak jackets; Mainly be to make with about 20 layers kevlar fiber goods to form, its principle is " firm with tough gram ", and the quality of this flak jackets has only 1.5 kilograms; Elastic force is 5 times of steel; But this flak jackets of processing with the conventional kevlar fiber of multilayer is very thick and heavy, still can produce soldier's action and disturb, and makes their more fatiguability.The third soft or hard combined type flak jackets is a liner with the soft material, is panel and reinforcing material with the hard material, has concentrated advantage rigid, soft flak jackets to a certain extent, but also has the shortcoming of rigid flak jackets simultaneously.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of thinner, lighter, the parcel scope is bigger and make soldier's flexibility can not receive the too New Type Military flak jackets of perturbation.
Technical solution of the present invention is achieved in that a kind of new liquid flak jackets, comprises the flak jackets body; Said flak jackets body is processed by the kevlar fiber of crossing through the STF soaked with liquid.
Technique scheme has following beneficial effect: this new liquid flak jackets has made full use of advantages such as the light weight, intensity height, hear resistance, anti-incised wound property of kevlar fiber, and combines behind the STF liquid reaction of flak jackets faster, and the degree of depth of rum point is then more shallow; This technology combines with traditional kevlar fiber flak jackets, can strengthen the flexibility that the soldier fights, and makes the thickness minimizing of flak jackets reach 45%; Through detecting, the performance of the bond each side of 10 layers of kevlar fiber and shearing resistance thick liquids all is superior to the undressed kevlar fiber of 30 bed thickness.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1 is the sketch map of new liquid flak jackets of the present invention;
Wherein: 1, flak jackets body.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of new liquid flak jackets of the present invention like accompanying drawing 1, comprise flak jackets body 1; Said flak jackets body 1 is processed by the kevlar fiber of crossing through the STF soaked with liquid.This programme is matrix with the kevlar fiber, and the STF liquid immersion is arrived all material layers of Kevlar.The original fiber of " Kevlar " flak jackets both can solidify STF, also extra protection can be provided, and the flak jackets that contains STF equally with tradition " Kevlar " flak jackets can be soaked in water, folding or make.
Said STF is the main component of liquid flak jackets, and this material contains the hard nanometer level aerosil particles that is suspended in a large number in the non-toxic polyethylene alcohol fluid, and when receiving external pressure, molecule can tightly combine.Under the normal condition, STF is just as other liquid, and is very soft, can be out of shape, and still, in case shell fragment or bullet contact it, this liquid just can be transformed into a kind of hard material moment, stops body to pass.
Said kevlar fiber is a kind of organic aromatic polyamide fibre, and its intensity is 6 times of equal thickness steel wire, and proportion is then little 5.5 times than steel wire, and intensity does not subtract when 200 ℃ of temperature, in the time of-45 ℃, also still keeps the toughness identical with normal temperature.
This new liquid flak jackets has made full use of advantages such as the light weight, intensity height, hear resistance, anti-incised wound property of kevlar fiber, and combines behind the STF liquid reaction of flak jackets faster, and the degree of depth of rum point is then more shallow.This technology combines with traditional kevlar fiber flak jackets, can strengthen the flexibility that the soldier fights, and makes the thickness minimizing of flak jackets reach 45%.Through detecting, the performance of the bond each side of 10 layers of kevlar fiber and shearing resistance thick liquids all is superior to the undressed kevlar fiber of 30 bed thickness.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
