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.
