Description
본 발명은 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품에 관한 것이다. 보다 상세하게는, 방탄 성능은 유지하면서 경량화 가능하도록 하고, 탄소나노튜브시트와 탄소나노튜브시트 간을 결합시키기 위해 친환경 바인더를 적용함으로써 인체에 무해하고, 악취 발생을 최소화한 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품에 관한 것이다.The present invention relates to a hybrid bulletproof product for security purposes using a carbon nanotube sheet. More specifically, the present invention relates to a hybrid bulletproof product for security purposes using a carbon nanotube sheet that is lightweight while maintaining bulletproof performance, and is harmless to the human body and minimizes odor by using an eco-friendly binder to bind carbon nanotube sheets together.
세계적으로 경량 방탄복에 대한 수요가 꾸준히 요구되어 있으며, 기존에 사용 중인 방탄복의 무게를 줄이고 방탄 성능을 유지하기 위한 연구개발이 추진되고 있는 추세이다. There is a steady demand for lightweight bulletproof vests worldwide, and research and development is being conducted to reduce the weight of existing bulletproof vests while maintaining their bulletproof performance.
최근 미국을 비롯한 전 세계적인 방탄복 개발 추세는 uni-directional fabric, multi-layer/axial fabric 등 전통적인 직물 형태 이외의 고성능 소재 적용을 통하여 경량화 및 박형화하는 방향으로 진행되고 있다. Recently, the global development trend of bulletproof vests, including those in the United States, is moving toward lighter and thinner forms by applying high-performance materials other than traditional fabric types, such as uni-directional fabric and multi-layer/axial fabric.
종래의 방탄복으로는 multi-layer/axial fabric 을 단독 또는 복합화함으로써 면밀도 5.0kg/m2∼6.0kg/m2 수준의 방탄복을 제시하고 있으나, 소재 자체가 매우 뻣뻣하고, 고가라는 단점이 있어 이를 해결할 수 있는 방탄 소재 개발을 위하여 집중적인 연구개발이 이루어지고 있다. Conventional bulletproof vests have been made by using multi-layer/axial fabrics alone or in combination to provide a bulletproof vest with an area density of 5.0 kg/ m2 to 6.0 kg/ m2 . However, the material itself is very stiff and expensive, so intensive research and development is being conducted to develop bulletproof materials that can solve these issues.
한편, 탄소나노튜브시트는 현재까지 알려진 가장 가벼운 방탄소재이며, 미국 등에서는 이미 탄소나노튜브시트의 양산화에 성공하여 다양한 분야에 적용 연구를 선행하고 있다. Meanwhile, carbon nanotube sheets are the lightest bulletproof material known to date, and countries such as the United States have already succeeded in mass producing carbon nanotube sheets and are conducting research on their application in various fields.
그러나, 국내에서는 탄소나노튜브시트에 관한 연구가 기초 연구 수준에 머물러 있으며 양산화를 통한 다양한 실용화 연구개발이 시급한 실정이다. However, in Korea, research on carbon nanotube sheets remains at the basic research level, and various practical research and development through mass production are urgently needed.

The first carbon nanotube sheet (20) has high strength and high elasticity, and is used in multiple layers, and is bonded between the first bulletproof fabric sheet (10) and the second bulletproof fabric sheet (30) described below.
제1 탄소나노튜브시트(20)는 8 플라이(ply) 내지 20 플라이(ply)로 이루어지며, 보다 바람직하게는 탄소나노튜브시트(30)는 8 플라이(ply) 내지 10 플라이(ply)로 이루어진다. The first carbon nanotube sheet (20) is made of 8 to 20 plies, and more preferably, the carbon nanotube sheet (30) is made of 8 to 10 plies.
또한, 제1 탄소나노튜브시트(20)는 1단 내지 5단으로 적층되어 형성된다. Additionally, the first carbon nanotube sheet (20) is formed by stacking in 1 to 5 layers.
제2 방탄직물시트(30)는 복수 개가 중첩되어 중간재 또는 후면재로 사용되고, 일측면이 제1 탄소나노튜브시트(20)와 결합된다. The second bulletproof fabric sheet (30) is used as an intermediate material or a backing material by overlapping multiple pieces, and one side is combined with the first carbon nanotube sheet (20).
일 실시예로서, 제2 방탄직물시트(30)는 단방향(UD) 초고분자량폴리에틸렌(UHMWPE, Ultra High Molecular Weight Polyethylene) 또는 아라미드 직물 중 선택된 1종 이상인 것을 특징으로 한다. As an example, the second bulletproof fabric sheet (30) is characterized by being at least one selected from among unidirectional (UD) ultra-high molecular weight polyethylene (UHMWPE) or aramid fabrics.
제2 탄소나노튜브시트(40)는 일측면은 제2 방탄직물시트(30)와 결합되고, 타측면은 제3 방탄직물시트(50)과 결합되고, 적어도 1개 이상 중첩되어 사용된다. The second carbon nanotube sheet (40) is combined with the second bulletproof fabric sheet (30) on one side and with the third bulletproof fabric sheet (50) on the other side, and is used with at least one or more overlapping layers.
제3 방탄직물시트(50)는 제2 탄소나노튜브시트(40)의 일측면과 결합되고, 복수 개가 중첩되어 사용되고, 후면재로 사용된다. The third bulletproof fabric sheet (50) is combined with one side of the second carbon nanotube sheet (40), and is used in multiple overlapping configurations, and is used as a backing material.
일 실시예로, 본 발명의 바람직한 실시예에 따른 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품은 제1 방탄직물시트(10), 제1 탄소나노튜브시트(20), 제2 방탄직물시트(30)가 순차적으로 적층되며, 탄소나노튜브시트와 단방향(UD) UHMWPE(Ultra High Molecular Weight Polyethylene)로 구성된 하이브리드 적층 구조를 형성한다.In one embodiment, a hybrid bulletproof product using a carbon nanotube sheet according to a preferred embodiment of the present invention comprises a first bulletproof fabric sheet (10), a first carbon nanotube sheet (20), and a second bulletproof fabric sheet (30) sequentially laminated to form a hybrid laminated structure composed of a carbon nanotube sheet and unidirectional (UD) UHMWPE (Ultra High Molecular Weight Polyethylene).
예컨대, 방탄가방인 경우, 제1 실시예에 따른 구조를 지니고, 제1 방탄직물시트, 제1 탄소나노튜브시트, 제2 방탄직물시트는 UHMWPE UD(단방향), 탄소나노튜브시트, UHMWPE UD(단방향) 순으로 적층된 구조로 이루어진다. For example, in the case of a bulletproof bag, it has a structure according to the first embodiment, and the first bulletproof fabric sheet, the first carbon nanotube sheet, and the second bulletproof fabric sheet are laminated in the order of UHMWPE UD (unidirectional), carbon nanotube sheet, and UHMWPE UD (unidirectional).
상기 방탄가방은 전면 및 후면을 구성하는 제1 방탄직물시트와 제2 방탄직물시트가 각각 UHMWPE UD(단방향)가 복수 개 겹쳐져 이용되고,(예컨대, 전면 및 후면에 각 4장씩), 전면과 후면이 대칭된 구조로 방호 설계가 이루어지는 것을 특징으로 한다. 이러한 구조는 전면과 후면 어느 쪽으로도 방호가 가능하다는 장점이 있다. The bulletproof bag is characterized in that the first bulletproof fabric sheet and the second bulletproof fabric sheet constituting the front and back are each made of multiple overlapping UHMWPE UD (unidirectional) sheets (e.g., four sheets each on the front and back), and the protection design is made with a symmetrical structure on the front and back. This structure has the advantage of providing protection on either the front or the back.
제2 실시예로, 본 발명의 바람직한 실시예에 따른 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품은 제1 방탄직물시트(10), 제1 탄소나노튜브시트(20), 제2 방탄직물시트(30), 제2 탄소나노튜브시트(40), 제3 방탄직물시트(50)가 순차적으로 적층되며, 아라미드(aramid) 직물, 탄소나노튜브시트, 단방향(UD) UHMWPE(Ultra High Molecular Weight Polyethylene)으로 구성된 하이브리드 적층 구조를 형성한다. In a second embodiment, a hybrid bulletproof product using a carbon nanotube sheet according to a preferred embodiment of the present invention is formed by sequentially laminating a first bulletproof fabric sheet (10), a first carbon nanotube sheet (20), a second bulletproof fabric sheet (30), a second carbon nanotube sheet (40), and a third bulletproof fabric sheet (50), thereby forming a hybrid laminated structure composed of an aramid fabric, a carbon nanotube sheet, and unidirectional (UD) UHMWPE (Ultra High Molecular Weight Polyethylene).
예컨대, 방탄복인 경우, 제2 실시예에 따른 구조를 지니며, 제1 방탄직물시트는 아라미드(aramid)직물 5층, 제1 탄소나노튜브시트는 8 플라이(ply) 1층 및 9 플라이(ply) 1층, 제2 방탄직물시트는 아라미드(aramid) 직물 2층, 제2 탄소나노튜브시트는 10 플라이(ply) 1층, 제3 방탄직물시트는 UHMWPE UD(단방향 초고분자량 폴리에틸렌) 2층으로 적층된 구조로 이루어진다. For example, in the case of a bulletproof vest, it has a structure according to the second embodiment, and the first bulletproof fabric sheet is laminated with a structure in which the first aramid fabric sheet is laminated with 5 layers of aramid fabric, the first carbon nanotube sheet is laminated with 1 layer of 8 plies and 1 layer of 9 plies, the second bulletproof fabric sheet is laminated with 2 layers of aramid fabric, the second carbon nanotube sheet is laminated with 1 layer of 10 plies, and the third bulletproof fabric sheet is laminated with 2 layers of UHMWPE UD (unidirectional ultra-high molecular weight polyethylene).
방탄직물시트(10,30,50) 및 탄소나노튜브시트(20,40)는 프레스에 의해 압착을 수행함으로써 적층 시 직물 층 간의 공기층을 감소시키고, 전체 중량 및 두께를 최소화할 수 있도록 하며, 후면 변형 및 직물 변형을 최소화할 수 있도록 한다. Bulletproof fabric sheets (10, 30, 50) and carbon nanotube sheets (20, 40) are pressed by a press to reduce the air layer between fabric layers during lamination, minimize the overall weight and thickness, and minimize rear deformation and fabric deformation.
본 발명의 바람직한 실시예에 따른 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품은 제1 방탄직물시트(10), 제1 탄소나노튜브시트(20), 제2 방탄직물시트(30), 제2 탄소나노튜브시트(40), 제3 방탄직물시트(50)가 적층된 구조로서, 3.6 kg/m2~3.86 kg/m2의 면밀도 중량을 가지는 것을 특징으로 한다. A hybrid bulletproof product using a carbon nanotube sheet according to a preferred embodiment of the present invention has a structure in which a first bulletproof fabric sheet (10), a first carbon nanotube sheet (20), a second bulletproof fabric sheet (30), a second carbon nanotube sheet (40), and a third bulletproof fabric sheet (50) are laminated, and is characterized by having an area density weight of 3.6 kg/m 2 to 3.86 kg/m 2 .
종래의 방탄직물(방탄복)은 방탄직물시트를 40층 이상 단순 적층한 구조로 형성되어 고중량이고, 두께가 두껍고, 후면 변형에 대한 저항이 낮았다. Conventional bulletproof fabrics (bulletproof vests) are formed by simply laminating 40 or more layers of bulletproof fabric sheets, and are therefore heavy, thick, and have low resistance to rear deformation.
기존의 방탄직물시트만을 사용하는 방탄복은 면밀도 5.0kg/m2 이상이 되어야 방탄 성능을 발휘하였으나, 본 발명에 따른 방탄 제품은 기존 방탄복 대비 면밀도가 20~26% 감소하여도 방탄 효과가 발휘될 수 있다는 장점이 있다. Existing bulletproof vests using only bulletproof fabric sheets exhibited bulletproof performance only when the area density was 5.0 kg/ m2 or higher, but the bulletproof product according to the present invention has the advantage of exhibiting bulletproof effects even when the area density is reduced by 20 to 26% compared to existing bulletproof vests.
또한, 본 발명에 따른 방탄 제품은 방탄 성능 면에서도 NIJ Standard 0101.06 기준 Level Ⅲ-A(시험탄두:.44 Magnum & .357 SIG)를 만족시킬 수 있다. In addition, the bulletproof product according to the present invention can satisfy NIJ Standard 0101.06 Level Ⅲ-A (test warhead: .44 Magnum & .357 SIG) in terms of bulletproof performance.
탄소나노튜브시트(20,40)는 복수 개가 겹쳐져 결합될 때, 각 탄소나노튜브시트 간 바인더를 이용하여 탄소나노튜브시트와 또 다른 탄소나노튜브시트 간을 결착시켜 탄소나노튜브시트 사이의 계면 결합력을 향상시킬 수 있도록 한다. When multiple carbon nanotube sheets (20, 40) are overlapped and combined, a binder is used between each carbon nanotube sheet to bind the carbon nanotube sheet to another carbon nanotube sheet, thereby improving the interfacial bonding strength between the carbon nanotube sheets.
탄소나노튜브시트(20,40)는 8 플라이(ply) 내지 20 플라이(ply)를 격자로 겹쳐 친환경 바인더 용액에 침지하고, 롤러를 이용하여 일정 압력으로 가압하여 과량의 용매를 짜준 후 잔여 용매를 제거하고, 150~160℃의 경화조건에서 경화처리하여 제조된 것을 특징으로 한다. Carbon nanotube sheets (20, 40) are characterized by being manufactured by immersing 8 to 20 plies in a grid shape, immersing them in an eco-friendly binder solution, applying pressure at a certain level using a roller to squeeze out excess solvent, removing the remaining solvent, and then curing under curing conditions of 150 to 160°C.
여기서, 바인더는 에폭시(epoxy)계, 폴리에스터(polyester)계 수지를 이용한다. 에폭시(epoxy)계 수지 및 폴리에스터계(polyester) 수지는 에탄올을 포함하는 알코올 류 중 선택된 1종을 단독 사용하거나 1종 이상을 혼합한 용매와 교반되어 준비된다. Here, the binder uses an epoxy-based resin or a polyester-based resin. The epoxy-based resin and the polyester-based resin are prepared by using only one selected from alcohols including ethanol or by mixing with a solvent containing one or more types.
종래에는 탄소나노튜브시트을 적층하기 위해, 탄소나노튜브시트 간을 결착시키는 데 있어서, 폴리아크릴나이트릴(PAN) 바인더를 적용하였고, 폴리아크릴나이트릴 바인더를 적용하는데 있어 사용되는 용매로서, DMF(Dimethylformamide) 용매를 이용하였다. 그러나, 종래에 이용한 DMF 용매는 매우 독성이 강하고, 잔류 용매 제거에 고온으로 처리해야 하거나 VOC(Volatile Organic Compound) 발생 등의 문제가 야기되는 문제점이 있었다. In the past, in order to laminate carbon nanotube sheets, a polyacrylonitrile (PAN) binder was applied to bind the carbon nanotube sheets together, and a DMF (Dimethylformamide) solvent was used as a solvent used in applying the polyacrylonitrile binder. However, the DMF solvent used in the past had problems such as being highly toxic, requiring high-temperature treatment to remove residual solvent, and causing problems such as the generation of VOC (Volatile Organic Compound).
반면, 본 발명에서 바인더 용액 제조시 용매로서 이용되는 알코올류는 제작공정과 최종제품에 있어 인체에 무해한 환경으로 구축될 수 있는 장점이 있다. On the other hand, alcohols used as solvents in the manufacture of the binder solution in the present invention have the advantage of being able to be constructed as an environment harmless to the human body in the manufacturing process and the final product.
본 발명은 미국 NIJ standard 0101.06 기준 Level ⅢA 등급의 연성 방탄복(soft armor)의 무게(내장 기준)를 20% 이상 감량한 민수용 방탄복을 실용화할 수 있도록 한다. The present invention enables the commercialization of a civilian bulletproof vest that reduces the weight (based on internal components) by at least 20% of a Level ⅢA grade soft armor according to the US NIJ standard 0101.06.
도 5는 본 발명의 바람직한 실시예에 따른 탄소나노튜브시트를 적용한 하이브리드 경호용 방탄제품 중 방탄가방의 사격테스트 결과를 나타낸 도면으로, 미국 NIJ Standard 0108.01 Type ⅢA(시험탄두 : .44 magnum) 등급 기준의 방탄 테스트를 진행하였으며, 상기 기준 방탄 테스트를 통과하였고, 면밀도 중량이 2.143kg/m2 으로, 기준 면밀도 대비 17.3% 감량하였음을 확인할 수 있다. FIG. 5 is a drawing showing the results of a shooting test of a bulletproof bag among hybrid bulletproof products for security purposes using carbon nanotube sheets according to a preferred embodiment of the present invention. The bulletproof test was conducted based on the US NIJ Standard 0108.01 Type ⅢA (test bullet: .44 magnum) grade standard, and it can be confirmed that the test passed the standard bulletproof test and the area density weight was 2.143 kg/ m2 , which is a 17.3% reduction compared to the standard area density.
