This study mainly investigates the effect of talc and calcium carbonate (CaCO3) as monotonic and hybrid fillers on the thermal, mechanical and morphological properties of polypropylene (PP). The hybrid composites, through the synergistic coalescence of positive characteristics from both fillers, have exhibited exceptionally good strength and toughness as compared to the monotonic composites. The nucleating ability and high aspect ratio of talc contributed towards the increment in strength while the isotropic nature of CaCO3 enhanced the toughness of the hybrid composites. Titanate surface treatments on talc and CaCO3 dramatically enhanced the ductility of both monotonic and hybrid composites. The composites were also subjected to natural weathering in Penang, Malaysia for 6 months. After exposure, the mechanical properties of monotonic composites deteriorated due to severe physical and chemical degradation. However, the hybrid composites exhibited better retention in mechanical...
