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 ℃ 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.
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 ℃, 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.
