Abstract

Currently, since carbon fiber reinforced plastics (CFRPs) are lightweight and have excellent physical properties, their demand has increased dramatically. Many works have studied the CFRPs based on recycled thermoplastics. In this study, the applicability of recycled composite was evaluated using recycled polyethylene terephthalate (PET). PET was collected from waste materials used in beverage bottles and processed to produce PET films. Optimal thermoforming temperature and time were analyzed by comparing the mechanical properties with forming temperature and time difference for producing PET films. CF mat and PET film were used to determine the suitable parameters for the optimum thermoforming of CF/PET composites. The mechanical properties of each thermoforming condition were verified by bending test. The degree of impregnation of the PET film into the CF mat was evaluated by cross-sectional photographs, whereas the interfacial properties were evaluated by interlaminar shear strength (ILSS). Ultimately, it was confirmed that the thermoforming condition for forming the CF/recycled PET composites yielding the optimal mechanical and interfacial properties was at $270^{\circ}C$ for 5 minutes.

탄소섬유 강화 복합재료는 가볍고, 우수한 물성을 가지고 있기 때문에 그 수요는 급격하게 증가되고 있다. 그에 따라, 탄소섬유 강화 복합재료의 기지로 재활용이 가능한 열가소성 수지를 사용한 복합재료 연구를 많이 진행하고 있다. 본 연구에서는 재활용 PET를 이용하여 재활용 복합재료에 대한 활용성 평가를 하였다. PET는 음료수 병으로 활용되는 폐기물을 수집하여 PET 필름을 제조하는 과정을 거쳤으며, PET 필름을 제조하기 위한 성형 온도와 시간의 차이에 따른 기계적 물성을 비교하여 최적의 성형온도와 시간을 분석하였다. 이를 바탕으로 재활용 PET 필름과 탄소섬유 매트를 이용하여 CF/PET 복합재료를 최적으로 성형하기 위한 변수를 관찰하였다. 성형 조건에 따른 기계적 물성을 굴곡시험으로 확인하였고, PET 필름이 탄소섬유 매트 내에 함침 되는 정도를 단면 사진으로, 그리고 계면 성질을 층간전단강도로 평가하였다. 궁극적으로 최적의 기계적 물성을 가지는 CF/PET 복합재료를 성형하기 위한 성형 조건이 $270^{\circ}C$와 5분임을 확인했다.
