Description

비구속조건의 전단농화유체 함침 직물이 삽입된 방탄복합재료, 방탄복 및 그 제조방법{A bullet-proof composite material in which unconstrained shear thickening fluid impregnated fabrics are inserted, a bullet-proof body armor and a method to manufacture the said material}A bullet-proof composite material in which unconstrained shear thickening fluid impregnated fabrics are inserted, a bullet-proof body armor and a method to manufacture the said material}

본 발명은, 공지되어 있는 일반 방탄직물 사이에 비구속조건의 전단농화유체 함침 직물을 삽입한 후 일반 방탄직물끼리만 가장자리부를 서로 박음질하거나 접착하거나 체결하여 일정한 구속조건을 줌으로써, 종래의 그 어떤 방탄재료보다 방탄성능이 더 뛰어나고, 무게가 가벼워 착용하기에 좋고, 제조비용도 절감 가능한, 비구속조건의 전단농화유체 함침 직물이 삽입된 방탄복합재료와 방탄복 및 그 제조방법에 관한 것이다.The present invention, by inserting a non-binding shear thickening fluid impregnated fabric between the known general bulletproof fabrics, and then put the edges of the ordinary bulletproof fabrics only to each other, or to bond or fasten the edges to give a certain constraint, any conventional bulletproof material The present invention relates to a ballistic composite material, a body armor, and a method of manufacturing the same, in which a shear thickening fluid-impregnated fabric of an unconstrained condition is inserted, which is more excellent in ballistic performance, is light in weight, and is good to be worn, and the manufacturing cost is also reduced.

전단농화유체(STF: Shear Thickening Fluid)란, 유체의 전단속도가 증가함에 따라 점도가 증가하는 유체로서, 외부로부터의 충격이 저속으로 가해질 때는 액체처럼 거동하고, 충격이 고속으로 가해질 때는 고체처럼 거동하는 물질을 일컫는다.Shear Thickening Fluid (STF) is a fluid whose viscosity increases as the shear rate of the fluid increases. It behaves like a liquid when the impact from the outside is applied at low speed and as a solid when the impact is applied at high speed. Refers to the material.

최근, 이러한 전단농화유체를 직물에 함침시켜 만든 재료, 즉, 전단농화유체 함침 직물로 액체방탄복을 제작하는 방법에 대한 연구가 미 육군연구소와 델라웨어 대학에서 진행되고 있는데, 특허문헌 1 및 특허문헌 2는 그 성과물이다.Recently, research into a method of manufacturing a liquid body armor using a material made by impregnating a shear thickening fluid into a fabric, that is, a shear thickening fluid impregnated fabric, is being conducted at the US Army Research Institute and the University of Delaware. 2 is the outcome.

전단농화유체 함침 직물을 방탄복 소재로 사용한다면, 종래 방탄복보다 훨씬 더 가볍고 유연하여 착용감이 좋은 방탄복을 제작할 수 있다.If the shear thickening fluid impregnated fabric is used as a body armor material, it is possible to manufacture a body armor that is much lighter and more flexible than conventional body armor.

하지만, 전단농화유체 함침 직물은 직물과 전단농화유체의 성질을 둘 다 가지고 있어, 외부로부터의 충격이 일정 속도 이내로 가해질 때는 그 속도에 비례하여 방탄성능이 증가하다가 일정 속도를 넘어설 경우 그 전보다 방탄성능이 더 나빠지는 현상이 나타난다. 즉, 전단농화유체 함침 직물을 적용한 방탄복이 고속의 탄환에 의해 뚫릴 수 있는 것이다.However, shear thickening fluid impregnated fabrics have both properties of fabric and shear thickening fluid. When the impact from the outside is applied within a certain speed, the ballistic performance increases in proportion to the speed. Performance worsens. That is, the body armor to which the shear thickening fluid impregnated fabric is applied can be pierced by a high speed bullet.

본 발명은 전단농화유체 함침 직물을 사용하는 방탄복합재료의 개량 또는 응용 기술에 관한 것으로서, 외부로부터 충격이 고속으로 가해지는 경우에도 높은 방탄성능이 발휘될 수 있고, 방탄성능이 동일한 경우 방탄복합재료를 구성하는 직물의 겹 수를 종래보다 더 줄일 수 있어 비용절감효과가 있으며, 무게가 가볍고 유연하게 변형될 수 있어 착용감이 우수한, 비구속조건의 전단농화유체 함침 직물이 삽입된 방탄복합재료와 이러한 방탄복합재료로 제작되는 방탄복 및 그 제조방법을 제공하는데 목적이 있다.The present invention relates to an improvement or application technology of a bulletproof composite material using a shear thickening fluid impregnated fabric, and can exhibit high ballistic performance even when an impact is applied at high speed from the outside, and in the case of the same ballistic performance, a ballistic composite material It is possible to reduce the number of layers of the fabric constituting more than conventional, cost-effective, lightweight and flexible deformation, excellent fit, bulletproof composite material with a non-binding shear thickening fluid impregnated fabric An object of the present invention is to provide a bulletproof body made of a bulletproof composite material and a method of manufacturing the same.

상기 과제가 해결 가능한 본 발명은 본 발명자들이 수행해 온 그동안의 많은 실험과 연구로부터 얻은 지식 및 결과에 기초하여 이루어진 것으로서, 가장자리부를 박음질하거나 접착하거나 체결하여 일정한 구속조건을 준 일반 방탄직물 사이에 비구속조건의 전단농화유체 함침 직물을 삽입하여 구성된 것을 특징으로 한다.The present invention capable of solving the above problems is made on the basis of the knowledge and results obtained from many experiments and studies that the present inventors have performed, and it is not bound between ordinary bullet-proof fabrics that are subjected to certain constraints by stitching, bonding or fastening edges. Characterized in that the condition is configured by inserting a shear thickening fluid impregnated fabric.

구체적으로, 본 발명에 따른 비구속조건의 전단농화유체 함침 직물이 삽입된 방탄복합재료는, 전단농화유체를 직물에 함침시켜 만든 비구속조건의 전단농화유체 함침 직물과, 비구속조건의 전단농화유체 함침 직물의 양면에 한 겹 이상으로 배치되어 전단농화유체 함침 직물을 제외한 가장자리부가 박음질이나 접착 또는 체결에 의해 구속되는 일반 방탄직물로 이루어진 것을 특징으로 한다.Specifically, the bulletproof composite material in which the non-binding shear thickening fluid-impregnated fabric is inserted according to the present invention is a non-binding shear thickening fluid-impregnated fabric made by impregnating the shear thickening fluid into the fabric, and the shear thickening of the non-binding condition. It is characterized by consisting of a general ballistic fabric is arranged in more than one layer on both sides of the fluid impregnated fabric, the edge portion except for the shear thickening fluid impregnated fabric is constrained by stitching or bonding or fastening.

여기서, 상술한 본 발명의 방탄복합재료는 일정 넓이의 직물에 전단농화유체를 함침시켜 비구속조건의 전단농화유체 함침 직물을 제조하는 단계와, 전단농화유체 함침 직물보다 넓이가 넓은 일반 방탄직물을 전단농화유체 함침 직물의 양면에 한 겹 이상으로 배치하는 단계와, 전단농화유체 함침 직물을 제외한 일반 방탄직물의 가장자리부를 박음질이나 접착 또는 체결에 의해 구속하는 단계를 거쳐 제조될 수 있다.Herein, the above-described bulletproof composite material of the present invention comprises the steps of preparing a shear thickening fluid-impregnated fabric of non-constrained condition by impregnating a shear thickening fluid in a fabric having a predetermined width, and a general bulletproof fabric having a wider width than the shear thickening fluid-impregnated fabric. Disposing the shear thickening fluid impregnated fabric in one or more layers, and the step of restraining the edge portion of the general bulletproof fabric other than the shear thickening fluid impregnated fabric by stitching or bonding or fastening.

또한, 본 발명에 따른 방탄복은, 일정 넓이로 제작되는 복수의 방탄복합재료가 수 mm 정도의 극히 작은 간격을 두고 서로 인접해 있거나 가장자리부가 서로 겹쳐져 있는 형태로 제작되는 것을 특징으로 한다. 하지만, 방탄복의 형태 등은 종래와 다를 바 없다.In addition, the body armor according to the present invention is characterized in that the plurality of body armor composite material produced in a predetermined area is produced in the form of adjacent to each other or the edge portion overlap each other at an extremely small interval of about several mm. However, the shape of the body armor is not different from the conventional.

본 발명에 따른 전단농화유체 함침 직물은, 예컨대, 일반 방탄직물에 전단농화유체를 함침시켜 만들 수 있는데, 이때 일반 방탄직물로서 아라미드 계열의 방탄직물이나 폴리에틸렌 계열의 방탄직물을 사용할 수 있다. 아라미드 계열의 방탄소재로는 케블라(kevlar)와 스타본드(stabond) 등이 있고, 폴리에틸렌 계열의 방탄소재로서 다이니마(dyneema)를 예로 들 수 있다. 유리섬유나 탄소섬유 등도 방탄직물의 소재로 사용될 수 있다.Shear thickening fluid-impregnated fabric according to the present invention, for example, can be made by impregnating the shear thickening fluid in a general ballistic fabric, in this case can be used aramid-based bullet-proof fabric or polyethylene-based bullet-proof fabric as a general ballistic fabric. Examples of aramid-based bulletproof materials include kevlar, starbond, and the like, and dyneema may be used as a polyethylene-based bulletproof material. Glass fibers or carbon fibers may also be used as the material of the bulletproof fabric.

이상과 같이 구성되는 본 발명의 방탄복합재료 및 방탄복에 따르면, 탄환 충돌시, 가장자리부가 서로 구속되어 있는 일반 방탄직물에 의해 탄환의 속도와 충격이 1차적으로 감소하고, 비구속조건의 전단농화유체 함침 직물이 탄환의 진행방향으로 변형되면서 탄환의 속도와 충격이 2차적으로 감소하여 탄환이 관통할 수 없게 된다. 따라서, 종래 구성의 방탄재료나 방탄복보다 더 높은 방탄성능이 발휘된다.According to the bulletproof composite material and the body armor of the present invention configured as described above, the bullet speed and impact of the bullet is primarily reduced by the general ballistic fabric in which the edges are bound to each other, and the shear thickening fluid under non-constrained conditions. As the impregnated fabric is deformed in the direction of the bullet's progression, the velocity and impact of the bullet decreases secondarily and the bullet cannot penetrate. Therefore, higher anti-ballistic performance is achieved than the anti-ballistic material or body armor of the conventional structure.

또한, 본 발명에 따른 비구속조건의 전단농화유체 함침 직물은 일반 방탄직물에 전단농화유체를 함침시켜 만든 것으로서 일반 방탄직물에 비해 방탄성능이 월등히 우수하기 때문에, 일반 방탄직물로만 구성된 종래의 방탄재료보다 더 적은 겹 수(layer수)로도 동일한 방탄성능이 발휘될 수 있다. 따라서, 전단농화유체의 사용에 따른 일부 비용의 상승을 고려하더라도 전체적으로는 방탄복합재료 또는 방탄복의 제조비용이 절감되는 효과가 있다.In addition, the shear thickening fluid-impregnated fabric of the non-constrained condition according to the present invention is made by impregnating the shear thickening fluid in the general bulletproof fabric, and excellent anti-ballistic performance compared to the general bulletproof fabric, the conventional bulletproof material consisting only of ordinary bulletproof fabric The same ballistic performance can be achieved with fewer layers. Therefore, even if some cost increases due to the use of shear thickening fluid, there is an effect of reducing the manufacturing cost of the bulletproof composite material or bulletproof clothing as a whole.

또한, 본 발명에 따른 방탄복합재료는 동일한 방탄성능을 갖는 종래의 방탄재료보다 일반 방탄직물의 사용량이 적어 무게가 가볍기 때문에, 종래의 방탄복보다 무게가 더 가벼운 방탄복을 제작할 수 있다. 게다가 본 발명에 따른 비구속조건의 전단농화유체 함침 직물은 탄환의 충격을 일부 흡수하므로, 관통하지 못한 탄환에 의해 발생하는 무딘 손상(blunt injury)을 줄여 줄 수 있다. 따라서, 종래의 방탄복보다 착용감이 좋고 활동에 지장을 주지 않으면서도 전투원의 생존가능성은 더욱 높일 수 있다.In addition, since the anti-ballistic composite material according to the present invention is lighter in weight than the conventional anti-ballistic material having the same anti-ballistic performance and the weight is light, it is possible to manufacture a body armor lighter than the conventional body armor. In addition, the shear thickening fluid-impregnated fabric of the non-constrained condition according to the present invention absorbs the impact of the bullet, thereby reducing blunt injury caused by the non-penetrating bullet. Therefore, it is more comfortable to wear than conventional body armor and can increase the survival of the combatant even without disturbing the activity.

Here, among the terms used in this specification, the term "constraints" refers to stitching or superimposing the edges of each fabric to prevent loosening from the edges of the fabrics produced or cut to a certain size. A portion of two or more fabrics is defined as sewn, glued or fastened. Thus, the term "non-constrained condition" means a state in which such a binding process is not performed.

도 1에 도시된 바와 같이, 본 발명에 따른 비구속조건의 전단농화유체 함침 직물이 삽입된 방탄복합재료는, 기본적으로, 전단농화유체를 직물에 함침시켜 만든 비구속조건의 전단농화유체 함침 직물(200)과, 비구속조건의 전단농화유체 함침 직물(200)의 양면에 한 겹 이상으로 배치되어 전단농화유체 함침 직물(200)을 제외한 가장자리부가 박음질이나 접착 또는 체결에 의해 구속되는 일반 방탄직물(100)로 구성된다.As illustrated in FIG. 1, the bulletproof composite material in which the non-binding shear thickening fluid-impregnated fabric according to the present invention is inserted is basically a non-binding shear thickening fluid-impregnated fabric made by impregnating the shear thickening fluid into the fabric. (200) and the general bullet-proof fabric is arranged in one or more layers on both sides of the non-constrained shear thickening fluid impregnated fabric 200, the edge portion except for the shear thickening fluid impregnated fabric 200 is constrained by stitching or bonding or fastening It consists of 100.

도면에 나타나 있듯이, 개개의 일반 방탄직물(100)은, 직물의 가장자리를 따라 구속부(100)가 형성되는데, 이 구속부(100)는, 예컨대, 직물의 가장자리를 스티치 테이프로 감싼 상태에서 박음질하여 만들 수 있다.As shown in the figure, the individual bulletproof fabric 100 is formed with a restraint 100 along the edge of the fabric, which is stitched, for example, with the edge of the fabric wrapped with stitch tape. You can make

도 2a는 본 발명에 따른 방탄복합재료의 일 실시예 및 이 방탄복합재료를 클레이 위트니스(clay witness)에 장착하여 300m/s의 속도로 탄도실험 한 결과를 나타낸 것으로서, 2장의 전단농화유체 함침 직물(200)을 사이에 두고 2장의 일반 방탄직물(100)이 앞에 배치되고 1장의 일반 방탄직물(100)이 뒤에 배치되어 있다.Figure 2a is an embodiment of the anti-ballistic composite material according to the present invention, and the result of ballistic experiment at a speed of 300m / s by mounting the bulletproof composite material in a clay witness (clay witness), two shear thickening fluid impregnated fabric Two general bulletproof fabrics 100 are placed in front and 200 normal bulletproof fabrics 100 are disposed between them.

전단농화유체 함침 직물(200)은 둘 다 비구속조건이며, 직물소재로 케블라가 사용되었다. 이에 대해, 3장의 일반 방탄직물(100)은 전부 구속조건이며, 직물소재로서 케블라가 사용되었다.Shear thickening fluid impregnated fabric 200 is both unconstrained, and Kevlar was used as the fabric material. On the other hand, all three bulletproof fabrics 100 are constraints, and Kevlar was used as the fabric material.

탄도실험은, 1장의 일반 방탄직물(100)이 클레이 위트니스 쪽을 향하도록 방탄복합재료를 배치한 상태에서 이루어졌다. 우측 사진은 탄도실험의 종료 후, 클레이 위트니스를 반으로 잘라 본 것인데, 상단측의 움푹 팬 부분이 탄환에 의해 밀려들어 간 부분이다.The ballistic experiment was conducted in a state where a bulletproof composite material was disposed so that one sheet of bulletproof fabric 100 faces the clay witness side. The photo on the right shows the clay witness cut in half after the end of the ballistic experiment, where the depressions in the upper side are pushed in by bullets.

도 2b는 도 2a의 비교예로서, 도 2a에 도시된 비구속조건의 전단농화유체 함침 직물(200) 대신, 양 측변에 구속부(310)가 형성된 구속조건의 전단농화유체 함침 직물(300)을 사용한 경우를 나타낸 것이다. 구속부(310)가 형성된 것 말고는 다른 점이 전혀 없었음에도, 우측 사진에서 볼 수 있듯이, 탄환이 클레이 위트니스를 관통해 버렸다.FIG. 2B is a comparative example of FIG. 2A. Instead of the unconstrained shear thickening fluid impregnated fabric 200 shown in FIG. 2A, the shear thickening fluid impregnated fabric 300 of the constraint condition in which the restraints 310 are formed on both sides is shown. It shows the case of using. The bullet penetrated the clay witness as shown in the photograph on the right, although there was no difference except that the restraint portion 310 was formed.

따라서, 도 2a 및 도 2b의 비교를 통해, 전단농화유체 함침 직물의 가장자리부를 비구속조건으로 할 때, 방탄성능이 극대화됨을 알 수 있다.Accordingly, it can be seen from the comparison of FIGS. 2a and 2b that the ballistic performance is maximized when the edge portion of the shear thickening fluid-impregnated fabric is not bound.
