초록
목재펄프를 결합재로 하고 탄소섬유를 보강재로 한 탄소섬유 강화 종이(CFR-paper)를 수초지 제조방법에 의하여 탄소섬유의 종류별, 함량별, 강화 종이의 평량별로 제조하였다. 탄소섬유 강화 종이 내에서 5 mm 길이의 탄소 단섬유는 비교적 균일하게 분산되었으나 탄소섬유 첨가량의 증가는 종이의 특성을 약화시켰다. 탄소섬유 강화 종이의 전기전도도는 탄소섬유의 함량이 증가할수록, 강화 종이의 평량이 증가할수록 증가하였으며, 이방성 피치계 탄소섬유(S-231)를 50 wt% 가한 80g/m2탄소섬유 강화 종이의 전기전도도는 0.609 S/cm에 도달하였다. 탄소섬유 강화 종이의 표면온도는 탄소섬유 함량이 증가함에 따라 선형적으로 상승하였다.
Carbon fiber reinforced paper (CFR-paper)s were prepared by the handsheet manufacturing method with a mixture of wood pulp as a binder and carbon fiber as a reinforcing material. The CFR-paper samples were prepared by varying the sources and contents of carbon fibers, and the weight of paper. Though the 5 mm chopped carbon fibers were evenly dispersed in the paper, the increase of carbon fiber content weakened the property of the papers. The electrical conductivity of the paper increased with an increase of carbon fiber content and reached to the level of 0.609 S/cm at 50 wt% anisotropic pitch based carbon fiber in the 80 g/m2 basis weight of paper. The surface temperature of reinforced paper linearly increased as increasing the carbon fiber content.
