The aramid fibers have a much higher tensile strength, toughness and heat resistance than conventional fibers. After its initial development, it is widely used in pajamas, curtains, work clothes, upholstery fabrics, and carpets.

이에따라, 본 발명의 실시예에 따른 복합 섬유 보강재는 전류가 흐르면 안되는 지하철 터널, 철도 터널, 통신선 지하박스, 지중선 전기박스 등의 보강구조물에 함침이 가능하고, 따라서 탄소섬유가 가지는 특성을 최대한 활용할 수 있는 것이다.Accordingly, the composite fiber reinforcing material according to the embodiment of the present invention can be impregnated into the reinforcing structures such as subway tunnel, railway tunnel, communication line underground box, underground electric box, which should not flow current, and thus can make the most of the characteristics of carbon fiber. It is.

여기서, 본 발명의 실시예에서는 상기 탄소섬유(10)와 보강섬유(20)는 물론 연결섬유(30)의 표면에 접착수지층(40)을 도포시켜 구성할 수도 있으며, 상기 접착수지층(40)은 에폭시 수지로서, 상기 혼합 직조를 통해 양방향으로 배열되는 상기 탄소섬유(10)와 보강섬유(20) 및 연결섬유(30)의 표면에 도포되어 형성되어, 상기 복합 섬유 보강재가 일정형상의 보강구조물(예; FRP)에 적용될 때 상기 보강구조물의 모재(예; 플라스틱)으로부터 복합 섬유 보강재의 들뜸이나 분리 또는 기포 현상이 발생되지 않도록 하면서, 상기 복합 섬유 보강재가 모재로의 함침이 이루어질 때 그 함침불량은 방지하는 한편, 건설현장에서의 직접 시공이 이루어지더라도 벽면이나 천정면 또는 기둥보 등에서 상기 복합 섬유 보강재가 접착 불량을 방지시킬 수 있도록 한 것이다.Here, in the embodiment of the present invention, the carbon fiber 10 and the reinforcing fiber 20 may be formed by applying an adhesive resin layer 40 on the surface of the connecting fiber 30 as well as the adhesive resin layer 40. ) Is an epoxy resin, which is formed by being applied to the surfaces of the carbon fiber 10 and the reinforcing fiber 20 and the connecting fiber 30 arranged in both directions through the mixed weaving, and the composite fiber reinforcing material is reinforced in a predetermined shape. When applied to a structure (e.g. FRP), the impregnation of the composite fiber reinforcement is impregnated with the base material, while preventing the lifting, separation or foaming of the composite fiber reinforcement from the base material (e.g. plastic) of the reinforcement structure. While preventing defects, the composite fiber reinforcement on the wall surface, ceiling surface or pillar beam, etc., even if direct construction is made in the construction site to prevent the adhesion failure.

즉, 복합 섬유 보강재에 수지를 함침시키면, 상기 함침에 의해 형성되는 수지피막에 의하여 건설현장에서 복합 섬유 보강재를 벽면이나 천정면 또는 기둥보에 시공시 복합 섬유 보강재가 들뜨거나 기포 현상이 나타나는 문제가 있고, 복합 섬유 보강재에 수지를 함침시키지 않으면 복합 섬유 보강재는 수지 접착이 안된 상태인 원사형태인 바 이를 건설현장에서 벽면이나 천정면 또는 기둥보에 시공시 복합 섬유 보강재가 분리되는 문제가 발생한다.That is, when the resin is impregnated with the composite fiber reinforcing material, the composite fiber reinforcing material is lifted or bubble phenomenon occurs when the composite fiber reinforcing material is constructed on the wall, ceiling or column beam in the construction site by the resin film formed by the impregnation If the composite fiber reinforcing material is not impregnated with the resin, the composite fiber reinforcing material is in the form of a yarn in which the resin is not bonded, which causes a problem that the composite fiber reinforcing material is separated at the construction site on the wall, ceiling, or column beam.

따라서, 상기와 같이 본 발명은 망사형 또는 격자형의 구조로서 양방향 배열되는 탄소섬유(10)와 보강섬유(20) 및 연결섬유(30)의 표면에 접착수지층(40)을 형성하여, 상기의 문제를 보완할 수 있도록 한 것이다.Therefore, as described above, the present invention forms an adhesive resin layer 40 on the surfaces of the carbon fibers 10 and the reinforcing fibers 20 and the connecting fibers 30 arranged in both directions as a mesh or lattice structure. It would be to supplement the problem.
