초록

본 연구에서는 무전해 니켈 도금 시간을 달리하여 제조한 자동차 시트용 탄소섬유 발열체의 발열 및 전기적 특성에 관하여 고찰하였다. 무전해 니켈 도금된 탄소섬유의 비저항 및 비열은 4-point probe method 및 differential scanning calorimetry (DSC)를 이용하여 분석하였으며, 표면 형상 및 표면 온도는 scanning electron microscope (SEM) 및 열화상 카메라를 이용하여 관찰하였다. 실험 결과, 도금시간의 증가에 따라 니켈 도금 두께 및 표면 온도는 증가하였으며, 반면에 비열 및 비저항은 도금시간이 증가함에 따라 감소하였다. 결과적으로 무전해 니켈 도금은 자동차 시트용 탄소섬유 발열체의 저항 발열 및 전기적 특성을 크게 향상시키는 것으로 판단된다.
