Abstract

In this work, we aim to investigate the specific gravity, thermal, and mechanical property changes of solid-state extruded polypropylene (PP)/calcium carbonate composites before and after orientation. For this work, we prepared $PP/CaCO_3$ composites having two different sizes (OM-1 and OM-10). On increasing the filler content, the specific gravity of the composites increases. The specific gravity of the oriented specimen containing filler in PP matrix is found to be much smaller than that of pre-specimen due to the formation of more microvoids. The presence of microvoids in case of oriented composite specimen significantly affected the tensile and flexural properties of the composites. It was observed that the effect of orientation on both flexural strength and modulus is much stronger than the effect of filler contents, regardless of the filler particle size.

본 논문에서는 고상압출된 폴리프로필렌/탄산칼슘 복합재료의 배향 전후의 비중, 열적 및 기계적 물성의 변화에 대해 연구하였다. 본 연구를 위해 두 가지 다른 크기를 갖는 탄산칼슘 충진제(OM-1 및 OM-10)를 폴리프로필렌에 첨가하여 폴리프로필렌/탄산칼슘 복합재료를 제조하였다. 충진제의 함량이 증가할수록 복합재료의 비중이 증가하였는데, 배향된 복합재료의 비중은 배향되지 않은 복합 재료에 비해 작은 것으로 나타났으며 이는 배향에 따라 발생된 미세공극으로 기인한 것이다. 배향 시 발생하는 이 미세공극은 복합재료의 인장 및 굴곡 물성에 큰 영향을 미치는 것으로 밝혀졌다. 굴곡강도 및 굴곡 탄성률에 미치는 배향의 영향은 충진제의 입자 크기에 상관없이 충진제의 함량의 영향보다 더 강한 것으로 나타났다.
