dc.description.abstract 불연속 탄소섬유-에폭시 복합재의 저항발열 특성에 관한 연구를 수행하였다. 1, 3, 5 wt.% 불연속 탄소섬유가 함유된 복합재 시험편을 초음파 처리와 캐스트 몰딩(cast molding)을 이용하여 제조하였다. 시편에 DC 전류 인가시 발생되는 저항열에 의한 시편의 표면온도 변화를 적외선 카메라를 이용하여 측정하였다. 발열온도를 예측하기 위해서 유한요소해석을 수행하였는데, 실측된 온도와 부합함을 확인하였다. 탄소섬유의 함량과 인가전압이 증가할수록 발열저항에 의해서 발생된 열은 증가함을 확인하였다. 복합재 내에서 균일한 온도분포를 얻기 위해서는 탄소섬유의 분산상태가 중요하며, 대기온과 습도 등 실험환경이 발열온도에 영향을 미치는 것으로 나타났다.

This study explores the resistive heating characteristics of discontinuous carbon fiber (CF)-epoxy composites. Test samples including 1, 3, and 5 wt.% CF were fabricated using sonication and cast molding processes. For heating performance characterization, DC currents were applied to the composite samples, and surface temperatures were evaluated visually and quantitatively using an infrared camera. To estimate the thermal performance of composites and verify the experimental results, finite element analyses were performed. The resistive heating mechanism was investigated in connection with CF loading and applied voltages. Resistive heating efficiency increased proportionately with CF concentration and applied voltage. To obtain homogeneous temperature distribution of the samples, high degree of CF dispersion is required.
