Description
본 발명은 금속복합재 플레이트와 이의 제조방법에 관한 것으로, 탄소섬유와 금속을 융착하여 이루어진 금속 복합재 플레이트 및 이의 제조방법에 관한 것이다. The present invention relates to a metal composite plate and a method for manufacturing the same, and more particularly, to a metal composite plate formed by fusing carbon fiber and metal and a method for manufacturing the same.
일반적으로 탄소섬유는 탄소원소의 질량 함유율이 90% 이상으로 이루어진 섬유장의 탄소 소재로서 폴리아크릴로니트릴(polyacrylonitrile) 또는 레이온으로부터 제조된 섬유형태의 유기 전구체 물질(탄화시키기 전의 물질)을 불활성화 분위기에서 열분해하여 얻어지는 섬유를 의미한다. In general, carbon fiber is a carbon material in the form of a fiber with a mass content of carbon elements of 90% or more, and refers to a fiber obtained by thermal decomposition of an organic precursor material (material before carbonization) in the form of a fiber manufactured from polyacrylonitrile or rayon in an inert atmosphere.
이는 철보다 가볍고 강도는 10배 이상 강하며, 내충격, 내열성, 화학적 안정성, 전기 열전도성, 마찰 마모특성, 생체친화성, 유연성 등의 우수한 특징을 가지고 있어 자동차, 항공 우주, 방산 및 반도체 등의 고부가가치 복합재료의 핵심소재로 사용되고 있다.It is lighter than iron, more than 10 times stronger, and has excellent characteristics such as impact resistance, heat resistance, chemical stability, electrical and thermal conductivity, friction and wear characteristics, biocompatibility, and flexibility, so it is used as a core material for high value-added composite materials in automobiles, aerospace, defense, and semiconductors.
이러한 탄소섬유 직물은 고급의 감도 개선을 위해 적용되는 평직(plain weave) 또는 능직(Twill)의 경우, 타 직물 구조 대비 240 g/m 2 이하의 저밀도 형태로 적용된다.These carbon fiber fabrics are applied in a low density form of 240 g/m2 or less compared to other fabric structures in the case of plain weave or twill weave applied for advanced sensitivity improvement.
한편, 수많은 탄소 원자가 결정 구조를 이루어 길게 늘어서 있는 분자 사슬로 이루어진 탄소섬유(Carbon Fiber, CF)는 매트릭스 수지와 혼합하여 탄소섬유 강화 플라스틱(Carbon Fiber Reinforced Plastic, CFRP)의 형태로 주로 사용된다.Meanwhile, carbon fiber (CF), which is made up of molecular chains in which numerous carbon atoms form a crystal structure and are long, is mainly used in the form of carbon fiber reinforced plastic (CFRP) mixed with matrix resin.
CFRP는 매트릭스 수지 내에서 탄소섬유가 일정한 공정에 의하여 침투된 상태로, 높은 인장 강도 및 강성을 제공하고, 매트릭스 수지는 탄소섬유를 감싸서 구조 재료로서의 형태를 유지하는 동시에 내충격성을 부여하는 탄소섬유 복합재이다.CFRP is a carbon fiber composite material in which carbon fibers are infiltrated into a matrix resin through a certain process, providing high tensile strength and rigidity, and the matrix resin wraps the carbon fibers to maintain their shape as a structural material while also providing impact resistance.
CFRP는 각각 알루미늄 대비 약 30%, 철강 대비 약 50%의 경량화 효과를 얻을 수 있어, 자동차 등에 사용되어 차체를 크게 경량화할 수 있으며, 이산화탄소 배출량을 감소시킬 수 있어 친환경 소재로서 주목받고 있다. CFRP can achieve a weight reduction effect of about 30% compared to aluminum and about 50% compared to steel, so it can be used in automobiles to significantly reduce the weight of the body and reduce carbon dioxide emissions, attracting attention as an eco-friendly material.
CFRP의 제조에 사용되는 매트릭스 수지는 열가소성 수지 외에도 불포화 폴리에스테르, 페놀 수지 및 에폭시 수지와 같은 열경화성 수지가 주로 사용된다. 특히, 에폭시 수지는 낮은 점도를 가지고 있어 탄소섬유와 가공이 유리하고 기계적 물성이 우수하여 가장 널리 사용되고 있다. The matrix resin used in the production of CFRP is mainly composed of thermosetting resins such as unsaturated polyester, phenol resin, and epoxy resin in addition to thermoplastic resins. In particular, epoxy resin is most widely used because it has low viscosity, is easy to process with carbon fibers, and has excellent mechanical properties.
그러나 복합재료 성형기술에 있어서의 가장 큰 난제라 할 수 있는 생산성 문제를 해결하기 어렵다. 구조재 용도로 사용되는 탄소섬유 복합재 성형공법은 수지가 미리 함침되어 있는 프리프레그(prepreg)를 적층한 후, 고온/고압에서 성형하는 방식이 주로 사용되고 있으나, 낮은 생산성과 높은 원가 문제로 인하여 수지주입 성형법(Resin Transfer Molding, RTM)으로 점차 대체되고 있는 실정이다. 수지 주입 성형법은 일정 형상을 지닌 탄소섬유 직조물을 금형에 넣은 후, 금형의 캐비티 내에 열경화성 수지를 주입하여 직조물에 함침시키는 것과 동시에 경화시킴으로써 성형품을 얻는 방법이다.However, it is difficult to solve the productivity problem, which is the biggest challenge in composite material molding technology. The carbon fiber composite molding method used for structural materials mainly uses a method in which prepregs that are impregnated with resin in advance are laminated and then molded at high temperature and high pressure. However, due to low productivity and high cost, it is gradually being replaced by resin transfer molding (RTM). Resin transfer molding is a method in which a carbon fiber woven fabric with a certain shape is placed in a mold, and a thermosetting resin is injected into the mold cavity to impregnate the woven fabric and harden it at the same time to obtain a molded product.
그러나 상술한 바와 같이 수지를 함침시켜 제조하는 경우, 수지고유의 물성 특성의 한계를 벗어날 수 없는 문제점을 가지고 있다. 특히 고열에서 성형플레이트의 내구성을 장담하기 어렵다. However, as described above, when manufacturing by impregnation with resin, there is a problem that it cannot overcome the limitations of the inherent physical properties of the resin. In particular, it is difficult to guarantee the durability of the molding plate at high temperatures.

Korean Patent Registration No. 10-2233567 discloses a method for manufacturing a high-density carbon fiber composite, and Korean Patent Publication No. 2013-0057008 discloses a method for bonding a carbon fiber high-density composite with a metal material.
그리고 대한민국 공개특허 제 2021-0122413호에는 탄소섬유 강화 금속 복합재의 제조방법이 게시되어 있다.And, Republic of Korea Publication No. 2021-0122413 discloses a method for manufacturing a carbon fiber reinforced metal composite.
게시된 금속복합재의 제조방법은 탄소섬유에 실리콘산화물(SiO2)을 코팅하는 제1단계, 상기 제1단계에서 코팅된 탄소섬유에 마그네슘(Mg) 분말을 부착시키는 제2단계, 상기 제2단계에서 부착된 탄소섬유와 복합재용 금속 분말을 혼합하여 혼합물을 준비하는 제3단계 및 상기 제3단계의 혼합물이 700 내지 850℃ 온도조건에서 반응 및 용탕화되어 금속 매트릭스에 강화된 탄소섬유가 함침되는 제4단계를 포함한다.The method for manufacturing the published metal composite includes a first step of coating carbon fibers with silicon oxide (SiO2), a second step of attaching magnesium (Mg) powder to the carbon fibers coated in the first step, a third step of preparing a mixture by mixing the carbon fibers attached in the second step with metal powder for a composite, and a fourth step of reacting and melting the mixture of the third step at a temperature of 700 to 850°C to impregnate the metal matrix with reinforced carbon fibers.
상술한 구성은 실린콘 산화물을 도포한 후 마그네슘을 부착시킨 것으로, 금속복합재의 구조적 강도를 높이는데, 한계가 있다. The above-described composition has limitations in increasing the structural strength of the metal composite by attaching magnesium after applying silicon oxide.

도 1은 본 발명에 따른 금속 복합재 플레이트 및 이의 제조방법을 나타내 보인 도면. FIG. 1 is a drawing showing a metal composite plate and a method for manufacturing the same according to the present invention.
본 발명은 금속 복합재 플레이트와 이의 제조방법에 관한 것으로, 이하에 일 실시예를 상세하게 설명하면 다음과 같다. The present invention relates to a metal composite plate and a method for manufacturing the same. An embodiment of the present invention is described in detail below.
본 발명에 따른 금속 복합재 플레이트는 탄소섬유로 이루어진 탄소섬유시트들과, 상기 탄소섬유시트들의 사이에 용융되어 함침됨으로써 플레이트를 형성하며 금속으로 이루어진 금속바인더를 구비한다. A metal composite plate according to the present invention comprises carbon fiber sheets made of carbon fibers and a metal binder made of metal that is melted and impregnated between the carbon fiber sheets to form a plate.
상기 탄소섬유시트는 탄소섬유소재로 만든 얇은 띠를 위사(緯絲)와 경사(經絲)로 하여 직각으로 교차 직조(織造)한 직물로 이루어질 수 있으며, 투명 합성수지시트들이 용융(熔融)되면서 격자(格子) 형태로 짜여진 탄소섬유시트의 공극(孔隙) 사이로 스며들면서 경화되어 투명 합성수지시트들 사이에서 탄소섬유시트가 일체로 고정될 수 있다. 이러한 합성수지시는 후수하는 금속바인더를 용융시켜 가압하는 과정에서 연소되어 배출되고, 금속바인더로 채워지게 된다. The above carbon fiber sheet can be made of a fabric in which thin strips made of carbon fiber material are woven perpendicularly as weft and warp yarns, and the transparent synthetic resin sheets are melted and seeped into the gaps of the carbon fiber sheets woven in a grid shape, thereby hardening and allowing the carbon fiber sheets to be integrally fixed between the transparent synthetic resin sheets. These synthetic resin sheets are combusted and discharged during the process of melting and pressurizing a subsequent metal binder, and are filled with the metal binder.
탄소섬유시트를 이루는 탄소섬유는 밀도가 낮고 강도, 탄성률, 화학적 안정성, 전기 전도성 등이 높은 전기/기계/화학적 특성이 우수한 소재로서 직경이 약 7μm인 탄소섬유 필라멘트(filament) 약 1000~320,000개로 구성된 탄소섬유 토우(tow)를 직조함이 바람직하다. Carbon fibers that make up carbon fiber sheets are materials with excellent electrical/mechanical/chemical properties, such as low density, high strength, elastic modulus, chemical stability, and electrical conductivity. It is desirable to weave carbon fiber tows composed of about 1,000 to 320,000 carbon fiber filaments with a diameter of about 7 μm.
한편, 상기 탄소섬유시트와 상호 계면접착되어 플레이트 형상의 성형성을 유지하는 금속바인더는 알루미늄, 알루미늄합금, 철, 철합금, 동, 동합금, 망간, 니켈, 아연으로 이루어진 군으로부터 선택된 적어도 하나로 이루어진다. 그러나 이에 한정되지 않고, 상기 탄소섬유시트를 이루는 탄소섬유의 용점보다 낮은 금속 및 비철금속은 바인더로서 사용 가능하다. Meanwhile, the metal binder that maintains the formability of the plate shape by interfacially bonding with the carbon fiber sheet is made of at least one selected from the group consisting of aluminum, aluminum alloy, iron, iron alloy, copper, copper alloy, manganese, nickel, and zinc. However, the present invention is not limited thereto, and a metal or non-ferrous metal having a lower melting point than the carbon fiber forming the carbon fiber sheet can be used as the binder.
상술한 바와 같이 구성된 금속복합재 플레이트 제조방법을 도 1을 참조하여 보다 상세하게 설명하면 다음과 같다. The method for manufacturing a metal composite plate configured as described above is described in more detail with reference to Fig. 1 as follows.
소정의 폭을 가지는 탄소섬유시트들과 금속바인더를 준비하는 제1단계를 수행한다. 탄소섬유시트(11)와 금속바인더(21)를 준비하는 제1단계는 상술한 바와 같이 탄소섬유 필라멘트를 이용하여 직조되며, 상기 금속바인더(21)는 알루미늄, 알루미늄합금, 철, 철합금, 동, 동합금, 망간, 니켈, 아연으로 이루어진 군으로부터 선택된 적어도 하나로 이루어질 수 있는데, 이는 금속분말 금속포일 또는 금속매쉬플레이트의 형태로 준비된다. A first step of preparing carbon fiber sheets having a predetermined width and a metal binder is performed. The first step of preparing the carbon fiber sheet (11) and the metal binder (21) is woven using carbon fiber filaments as described above, and the metal binder (21) may be made of at least one selected from the group consisting of aluminum, aluminum alloy, iron, iron alloy, copper, copper alloy, manganese, nickel, and zinc, and this is prepared in the form of a metal powder metal foil or a metal mesh plate.
상기와 같이 준비된 탄소섬유시트들은 롤 상태로 감긴 상태에서 풀리면서 상호 적층된 상태를 이루게 되는데, 이러한 과정에서 이들의 사이에 금속바인더를 개재시키는 제 2단계를 수행한다. The carbon fiber sheets prepared as described above are rolled and unwound to form a mutually laminated state, and a second step of interposing a metal binder between them is performed during this process.
상기 금속바인더가 포일 또는 매쉬플레이트로 이루어진 경우, 롤에 감긴 상태에서 탄소섬유시트들의 사이로 공급될 수 있으며, 분말의 형태로 이루어진 경우,금속분말이 노즐을 통하여 탄소나노섬유시트의 사이에 공급된다. 이때에 분말상의 금속바인더가 탄소섬유시트를 통과하지 못하도록 공급되는 탄소섬유시트의 하면에는 가이드플레이트(미도시)가 설치될 수 있다. If the above metal binder is made of a foil or a mesh plate, it can be supplied between the carbon fiber sheets in a roll-wound state, and if it is made in the form of a powder, the metal powder is supplied between the carbon nanofiber sheets through a nozzle. At this time, a guide plate (not shown) may be installed on the lower surface of the carbon fiber sheet through which the powder-form metal binder is supplied to prevent it from passing through the carbon fiber sheet.
그리고 금속바이더(21)가 개재된 상태로 적층된 탄소섬유시트(11)를 가열로의 내부를 통과시켜 고온으로 가열하여 금속바인더를 용융시킴과 아울러 가열로(30)의 내부에 설치된 복수쌍의 가압롤러(40)들을 이용하여 금속바인더(11)가 적층된 탄소섬유시트를 가압하는 제 3단계를 수행한다. And the third step is performed by passing the laminated carbon fiber sheets (11) with the metal binder (21) interposed through the inside of a heating furnace and heating them at a high temperature to melt the metal binder, and at the same time pressurizing the carbon fiber sheets laminated with the metal binder (11) using multiple pairs of pressurizing rollers (40) installed inside the heating furnace (30).
가압롤러들에 의해 가압된 탄소섬유들의 사이로 용융된 금속들에 의해 결착됨과 아울러 함침되도록 한다. 탄소섬유시트와 금속바인더의 사이에 높은 계면 접착강도를 형성할 수 있다. The carbon fibers are pressed by the pressurizing rollers and impregnated with the molten metals. A high interfacial adhesive strength can be formed between the carbon fiber sheet and the metal binder.
상기 제 3단계를 수행하는 과정에서 상기 탄소섬유시트(11)에 합성수지 필름이 설치된 경우, 가열 시 탄화되어 제거된다. In the process of performing the above third step, if a synthetic resin film is installed on the carbon fiber sheet (11), it is carbonized and removed when heated.
상술한 바와 같이 탄소섬유시트(11)와 금속바인더(21)가 융착되어 이루어진 금속복합재 플레이트는 물, 열매체유, 공기 등과 같은 냉각매체를 이용하여 냉각하는 제 4단계를 수행한다. As described above, the metal composite plate formed by fusing a carbon fiber sheet (11) and a metal binder (21) undergoes a fourth step of cooling using a cooling medium such as water, heat transfer oil, air, etc.
상술한 바와 같이 제조된 금속 복합재 플레이트는 탄소섬유와 금속의 복합체 탄소섬유와 수지의 복합재의 단점인 고열에서의 취약성과 재료의 낮은 신뢰도를 보완하고, 탄소섬유와 금속의 장점인 고온 강도, 낮은 열팽창계수, 내열충격성, 높은 열전도율, 기타 전기적 물성 등의 장점을 갖는다. The metal composite plate manufactured as described above has the advantages of carbon fiber and metal composites, such as high temperature strength, low thermal expansion coefficient, thermal shock resistance, high thermal conductivity, and other electrical properties, while complementing the disadvantages of carbon fiber and metal composites, such as high temperature vulnerability and low material reliability.
또한 본 발명의 제조방법은 별도의 함침공정 없이 가열로과 가압이 동시에일루어지게 되므로 제조공정이 단순하여 제조원가를 줄일 수 있으며, 제조된 금속 복합체는 기공율이 3% 이하로 낮고, 내구성이 뛰어나며, 내열성이 좋고, 열전달 속도가 빠른 복합체라는 장점이 있다.In addition, since the manufacturing method of the present invention simultaneously performs heating and pressurization without a separate impregnation process, the manufacturing process is simple and the manufacturing cost can be reduced. In addition, the manufactured metal composite has the advantages of being a composite with a low porosity of 3% or less, excellent durability, good heat resistance, and a fast heat transfer rate.
특히, 금속 복합재는 물성을 좌우하는 탄소섬유의 파괴현상이 없이 플레이트를 제조할 수 있으며, 각종 형강을 제조하기 위한 중간재로 사용할 수 있으므로 제철, 제강업, 화학공업, 각종 산업에 적용 가능하다. In particular, metal composites can be used to manufacture plates without the destruction of carbon fibers, which determines physical properties, and can be used as intermediate materials for manufacturing various types of shaped steel, so they can be applied to iron and steel manufacturing, chemical industry, and various other industries.
