초록

지구 온난화 억제를 위한 전 세계적인 연비규제에 발맞춘 해결책으로 자동차에 경량구조복합재료를 적용하는 것이 메가트렌드로 인식되고 있다. 본 연구에서는 수리, 폐기 및 재활용 측면에서 유리한 열가소성 탄소섬유강화플라스틱의 적용을 극대화하기 위해 전도특성이 요구되는 부품 대체 이슈에 대응할 수 있는 기술적 접근을 제공하는 것을 목표로 수행되었다. 저점도 중합 가능한 기지재의 특성을 활용하여 전도성 필러를 파우더 믹싱 방법으로 균일하게 혼입하면서도 우수한 함침 특성을 나타내는 열가소성 탄소섬유강화플라스틱 제조방법에 기초하여 카본블랙, 탄소나노튜브, 그래핀 나노플레이틀렛, 흑연, 피치계 탄소섬유 등 다양한 탄소기반 전도성 필러를 최대 함량까지 혼입하여 전기저항 및 열전도도를 비교하여 고찰하였다. 전도성 탄소 필러의 종류나 형태보다는 최대 혼입량이 시편의 전도 특성을 제어하기 위해 가장 중요한 인자임을 확인하였고, 전기전도 특성을 향상시키기 위해서는 1차원 형태의 전도성 탄소필러를 적용하는 것이 유리할 수 있는 반면 열전도 특성을 향상시키기 위해서는 2차원 형태의 전도성 탄소필러를 적용하는 것이 유리 할 수 있다는 실험 결과를 확인하였다. 본 연구의 결과들은 열가소성 탄소섬유강화플라스틱의 전도 특성을 제어하기 위한 최적 구조 설계에 잠재적인 통찰력을 제공할 수 있다.

The application of lightweight structural composites to automobiles as a solution in line with global fuel economy regulations to curb global warming is recognized as a megatrend. This study was conducted to provide a technical approach that can respond to the issue of replacing parts that require conductive properties to maximize the application of thermoplastic carbon fiber reinforced plastics (CFRPs), which are advantageous in terms of repair, disposal and recycling. By utilizing the properties of the low-viscosity polymerizable oligomer matrix, it was possible to prepare a thermoplastic CFRP exhibiting excellent impregnation properties while uniformly mixing the conductive filler. Various carbon-based conductive fillers such as carbon black, carbon nanotubes, graphene nanoplatelets, graphite, and pitch-based carbon fibers were filled up to the maximum content, and electrical and thermal conductive properties of the fabricated composites were compared and studied. It was confirmed that the maximum incorporation of filler was the most important factor to control the conductive properties of the composites rather than the type or shape of the conductive carbon filler. Experimental results were observed in which it might be advantageous to apply a one-dimensional conductive carbon filler to improve electrical conductivity, whereas it might be advantageous to apply a two-dimensional conductive carbon filler to improve thermal conductivity. The results of this study can provide potential insight into the optimization of structural design for controlling the conductive properties of thermoplastic CFRPs.
