초록

탄소섬유(CF) 강화 폴리프로필렌(PP) 복합재료의 수요는 증가되고 있다. 본 연구에서는 재활용 횟수에 따라 변화되는 복합재료의 물성 변화를 관찰하였다. CF 함량을 20% 함량으로 조성한 복합재료에 대해서 재활용 횟수에 따른 기계적 물성 평가를 진행하였다. 인장, 굴곡, Izod 동적 피로 실험에 따른 영향을 확인하였다. CF/PP 복합재료의 계면 물성을 평가하기 위해 젖음성 평가와 파단면을 FE-SEM으로 확인하였다. 재활용 횟수에 따라 섬유와 기지는 변화된다. CF/PP 복합재료는 재활용 할수록 섬유와 기지간의 계면에 열 데미지와 분쇄 과정에 의한 결합력 감소가 확인하였다.

Carbon fiber (CF) reinforced polypropylene (PP) compositeis was increased to amount consumed. In this study, recycle of composites by recycle times. CF was containing 20%. Mechanical and interfacial propertis of CF/PP was evaluation for number of recycle time. Mechanical assessment of CF/PP was tension, bending, fatigue tension test and izod test method. Interfacial assessment of CF/PP was wettability test and FE-SEM of fracture surface method. Fiber and matrix was changed to recycle time. The more recycle of CF/PP, the more interfacial bonding was decreased. Because fiber and matrix was damaged to thermal damage. And then reinforced CF was shorter than original shape.
