Abstract

PP/KF felt was used to load a high content of kenaf fiber (KF) into polypropylene (PP), and polyurethane (PU) was used as a binder. In order to find an optimum composition ratio of the PU binder, the flexural strength of the PP/KF/PU felt composite according to the isocyanate and polyol ratio was evaluated. PP-g-MAH grafted with maleic anhydride (MAH) was applied as a compatibilizer. Tensile, flexural, and impact properties were evaluated to consider changes in mechanical properties of the PP/KF/PU felt composite, and the properties were improved.

폴리프로필렌(polypropylene, PP)에 고 함량의 케나프 섬유(kenaf fiber, KF)를 투입하기 위해 PP/KF 펠트가 사용되었으며, 바인더로 폴리우레탄(polyurethane, PU)이 사용되었다. PU 바인더의 조성비 선정을 위해 이소시아네이트와 polyol 비율에 따른 PP/KF/PU 펠트 복합체의 굴곡 강도를 평가하였다. 상용화제로 말레인산 무수물(maleic anhydride, MAH)이 그라프트된 PP-g-MAH가 적용되었다 PP/KF/PU 펠트 복합체의 기계적 물성 변화를 고찰하기 위해 인장, 굴곡 및 충격 특성을 평가하였고, 기계적 물성이 개선됨을 확인하였다.
