초록
본 연구에서는 펠트의 제조방향과 폴리(에틸렌 테레프탈레이트)(PET)/케냐프 섬유(KF) 펠트 적용이 폴리프로필렌(PP)/KF 복합체 물성에 미치는 영향을 고찰하였다. PP/KF와 PP/KF-PET/KF 2-layer 복합체의 제조 시 바인더로 폴리우레탄(polyurethane, PU)을 사용하였으며 150 °C, 10 MPa의 조건에서 half-folding 방법으로 가열프레스를 이용하여 제조하였다. 인장, 3점 굽힘시험 및 아이조드 테스트가 복합체의 기계적 물성을 평가하기 위해 수행되었고, 시험결과를 이용하여 니들 펀칭 제조방향과 기계적 물성과의 상관관계를 규명하였다.
In this study, the effect of felt fabrication direction and addition of poly(ethylene terephthalate) (PET)/kenaf fiber (KF) felt on the properties of polypropylene (PP)/KF composites were investigated. Polyurethane (PU) was used as a binder in the preparation of the PP/KF and PP/KF-PET/KF 2-layer composites, and the composites were manufactured by half-folding method using by hot press at 150 °C and 10MPa. The tensile, three-point bending, and Izod impact tests were performed to evaluate the composite’s mechanical properties, and then the correlation between mechanical properties and needle-punching direction was also verified by the test results.
