초록

본 연구는 폴리프로필렌/마이카 복합재료의 고상압출에 의한 배향에 따른 기계적 물성의 변화에 관한 연구이다. 마이카 함량이 증가할수록 복합재료의 비중이 증가하였다. 하지만 고상압출에 따른 배향에 의해 복합재료의 비중은 미세공극의 발생으로 말미암아 비중은 배향 전에 비해 현저히 감소하는 것으로 나타났다. 이러한 미세공극의 존재는 복합재료의 인장 및 굴곡물성에 큰 영향을 미치는 것으로 나타났다. 고상압출 여부에 관계없이 마이카 함량이 10 wt%일 때 최대 굴곡 물성이 관찰되었다.

The purpose of this work is to investigate the specific gravity, thermal, and mechanical property changes of polypropylene (PP)/mica composites before and after solid-state extrusion. On increasing the filler content, the specific gravity of the composites increased. 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 the case of oriented composite specimen significantly affected the tensile and flexural properties of the composites. Both flexural strength and modulus of the composites showed maxima when the mica contents was 10 wt%, regardless of the orientation via solid state extrusion.
