Abstract
범용 PAN계 탄소섬유를 1,500 ℃까지 열처리한 후 탄소함량, 결정화도, 결정크기를 분석하고 이들의 변화에 따른 표면의 발열특성을 조사하였다. PAN계 탄소섬유의 결정화도, 결정크기는 열처리 온도가 1,000에서 1,500 ℃로 증가하는 동안 각각 37.08에서 53.69%, 1.62에서 1.82 nm로 증가하였고, 탄소섬유의 초기표면발열온도는 결정화도, 결정크기가 증가할수록 1차식으로 비례하여 증가하였다. 따라서 탄소섬유의 결정화도와 결정크기를 표면발열온도의 상승을 측정하여 간접적으로 신속하게 추정할 수 있게 되었다.
General purpose PAN-based carbon fibers were heat treated up to 1500 ℃, and analyzed their carbon contents, crstallinity, and crystalline size(Lc). Exothermic characteristics of carbon fiber were investigated in relation to crystallinity, and crystalline size(Lc). Carbon contents, crystallinities, and crystalline size(Lc) of PAN-based carbon fibers increased from 37.08 to 53.69%, and 1.62 to 1.82 nm, respectively as the increase of heat treatment temperature from 1000 ℃ to 1500 ℃. Initial surface temperature of fiber tow also linearly increased as the increase of crystallinity, and crystalline size(Lc). Therefore, the crystallinity and crystal size(Lc) of carbon fibers can indirectly and rapidly be estimated by measuring the surface temperature increase.
