More Information
Summary:The present invention relates to a carbon fiber reinforced grid material and a manufacturing method thereof, wherein the grid material is formed by intersecting reinforcing fibers in a weft direction and reinforcing fibers in a warp direction, at least one of the reinforcing fibers in the weft and warp directions includes carbon fibers coated with a first thermoplastic resin, and at least one of the weft and the warp is knitted with low melting point fused yarns. According to the present invention, it is possible to provide a carbon fiber reinforced grid material for a concrete structure, which has bending flexibility as well as an increased tensile strength and a reduced elongation of a fiber reinforcing material by greatly enhancing the contact strength of warp and weft. 본 발명은 위사 방향의 보강섬유와, 경사 방향의 보강섬유가 서로 직교하여 이루어진 그리드로, 상기 위사 방향의 보강섬유와 경사 방향의 보강섬유 중 어느 하나 이상은 제1열가소성 수지로 표면이 코팅된 탄소섬유를 포함하고, 상기 위사와 경사 중 어느 하나 이상은 저융점융착사로 경편직(Knitting)한 것을 특징으로 하는 탄소섬유보강 그리드 및 이의 제조방법에 관한 것이다. 본 발명에 따르면, 경사와 위사의 접점 강도를 크게 향상시킴으로써 섬유보강재의 인장강도를 증가시키고, 신도를 감소할 뿐만 아니라, 굴곡유연성을 갖는 콘크리트 구조물용 탄소섬유 보강 그리드를 제공할 수 있다.
