Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet type bulletproof material using a shear thickening fluid, and more particularly, to a wet bullet type bulletproof material using a shear thickening fluid, Wherein the shear thickening fluid pack is formed by filling a plastic pack with a shear thickening fluid in a suspension, sol, or gel state. The present invention relates to a bulletproof material that improves performance.
The bulletproof material should have impact resistance to protect the body from external impact such as bullet, small structural strain, and light weight, so that it should be excellent in wearability. As a result, fibers having high strength, high elasticity, high heat resistance and low specific gravity are used as bulletproof materials.
As a typical anti-armor fiber, ultra high molecular weight polyethylene (UHMWPE) is available. The fibers are known to have the highest impact resistance among commercially available synthetic resins, and are excellent in abrasion resistance, chemical resistance, and heat resistance, and are used in various industrial fields such as riding clothes and racing suits, and in particular, in protective equipment such as armor and helmet . In the case of the armed forces, Dyneema-made bulletproof equipment produced by the DSM company located in the Netherlands, which is the polyethylene-based bulletproof fiber, was provided to soldiers dispatched to Iraq.
However, in order for the ultrahigh molecular weight polyethylene to exhibit the bulletproof performance including the impact resistance as described above, it needs to have a sufficient thickness to be folded in layers, and even if it overlaps, There is a problem that it can not be applied to a bullet-proof product requiring high bulletproof ability.
Accordingly, a bulletproof material containing a shear thickening fluid and a shear thickening fluid is being developed on the bulletproof fiber.
However, in the case of manufacturing a bulletproof material by coating the bulletproof fiber with only a shear thickening fluid and drying the bulletproof fiber, or by impregnating the bulletproof fiber with a shear thickened fluid and drying the bulletproof fiber to produce a bulletproof material, We remain in developing materials.
That is, in the above case, when the shearing-concentrated fluid is used as a dry type, the effect when the shearing-concentrated fluid is in the state of suspension, sol or gel can not be completely obtained, There is a limit to improvement.
Therefore, the inventors of the present invention have made efforts to solve the above-mentioned problems, and to provide a wet bullet-proof bulging material containing at least two or more bulletproof fabric layers and a shear-thickening fluid layer formed by attaching a shear- The inventors of the present invention have found that the bullet-proofing fluid pack of the bulletproof material improves the bulletproof performance of the bulletproof material by forming the sheath-thickening fluid in the state of suspension, sol or gel filled in the plastic pack, .
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wet type bulletproof material using a shear thickening fluid.
Another object of the present invention is to provide a method for manufacturing a wet type bulletproof material using a shear thickening fluid.
It is another object of the present invention to provide a bulletproof article which is manufactured using the bulletproof material.
According to an aspect of the present invention,
And a sheathed thickening fluid layer formed by attaching a sheathed thickening fluid pack inserted between the bulletproof fabric layer and formed of a bulletproof fabric, wherein the sheathed thickening fluid pack comprises a suspension, wherein a shear thickening fluid in a sol or gel state is filled in a plastic pack to form a wet type bulletproof material using a shear thickening fluid.
According to an aspect of the present invention,

The present invention also provides a method of manufacturing a wet bulletproof material using a shear thickening fluid.
According to an aspect of the present invention,
The present invention provides a bulletproof article which is manufactured using the bulletproof material.
The present invention relates to a method of applying a shear-thickening fluid to a bullet-proof fabric by applying a shear-thickening fluid using a shear-thickening fluid pack packed in a pack in a suspension, sol or gel state, There is an effect that the back deformation is reduced and the impact strength is increased as compared with the dry type bulletproof material.
Specifically, in the case of the present invention, the shearing-concentrated fluid pack is packed in a pack in the form of a suspension, sol or gel. The shearing-concentrated fluid pack is inserted into at least two layers of a bullet- Solids or gel state of the shear-thickening fluid pack effectively absorbs and disperses the impact energy when the shock such as an external bullet is applied to the shear-concentrated fluid pack, The rear surface deformation of the bulletproof material is reduced, the impact strength is increased, and the activity is imparted depending on the state of the suspension, the sol or the gel state.
In addition, since the shock absorbing and dispersing effect can be effectively absorbed by the shock absorbing action of the shear-thickening fluid pack, the thickness of the bulletproof material can be reduced to make a light bulletproof garment.
Further, by further including an inorganic material in the shearing-concentrated fluid, it is possible to further improve the bulletproof performance such as the back deformation and the impact strength.
