초록

열가소성 고분자 복합재료 개발을 위하여 매트릭스수지로는 폴리프로필렌(PPF) 섬유를 사용하고 유기계 강화섬유로 비닐론(VF), 아라미드(KF) 및 나일론(PAF) 섬유 등을 사용하여 복합매트를 얻은다음 압축 성형하여 고분자 복합재료를 제조하였다. 제조한 고분자 복합재료의 충격 특성 및 형태학적 특성 등을 측정하였다. 아이조드충격강도는 VF/PP가 크며, 고속충격특성은 KF/PP계가 약간 크게 나타났다. Ductility Index(Dl)는 VF/PP>KF/PP>PAF/PP 순으로 나타났으며 VF/PP의 최대 DI값은 섬유중량분율이 20%일 때 2.43이었다. 유기섬유 충전률은 20~30%가 최적값이었으며 SEM 관찰로 섬유분산상태 및 배향성은 양호함을 확인하였다. 결론적으로 VF/PP 복합재료가 KF/PP 및 PAF/PP 복합재료에 비해 계면접착력이 가장 우수하였다.

The fiber reinforced thermoplastic composites(FRTP) were prepared with polypropylene fiber(PPF) as matrix and vinylon(VF), Aramid(KF) or nylon fiber(PAF) as reinforcing materials using the integrated fiber mixing apparatus. The composite sheets were prepared by compression molding and their impact and morphological properties were characterized. VF/PP system showed the maximum value in Izod impact strength, while KF/PP system showed the maximum value in high rate impact properties. Ductility Index(DI) order was VF/PP>KF/PP>PAF/PP. A maximum DI for VF/PP, 2.43, was obtained when the weight fraction of VF was 20%. The optimum amount of the reinforcing organic fiber was found to be 20~30%. As a result, it is concluded that VF/PP system has better interfacial adhesion properties than either KF/PP or PAF/PP.
