The present invention relates to a carbon surface heating element for a ceiling interior material of a vehicle which effectively heats the inside of a vehicle before an engine coolant is heated in winter and excellent durability. In particular, the carbon surface heating element for the ceiling interior material of the vehicle includes: a carbon heating sheet formed by performing paper-making and drying a carbon fiber dispersion composition in which carbon fibers and polyethylene short fibers are dispersed in water; and an electrode formed on both ends of the carbon heating sheet.
본 발명은 겨울철에 차량의 엔진 냉각수가 가열되기 전에 차량 내부를 효과적으로 난방이 가능하고 내구성이 우수한 차량의 천장 내장재용 탄소면상발열체에 관한 것으로서, 특히 차량의 천장 내장재 내에 배치되는 탄소면상발열체로서, 물에 탄소섬유 및 폴리에틸렌 단섬유를 분산시킨 탄소섬유 분산조성물을 초지 및 건조시킨 탄소발열시트와; 상기 탄소발열시트의 양단부에 각각 형성되는 전극;을 포함하는 것을 특징으로 한다.
