Calcium carbonate (CaCO 3 ) reinforced polypropylene/ ethylene propylene rubber (PP/EPR) copolymer composites for automotive use were developed by means of extrusion and injection molding process. Three kinds of CaCO 3 (stearic acid treated and untreated) nanoparticles and microparticles were used as fillers. The influence of stearic acid, particle size, and filler content on the state distribution and morphology were investigated by SEM and rheological measurements. Two different morphologies were observed: EPR and CaCO 3 dispersed in the PP matrix and a core shell structure, depending on the interactions between EPR and CaCO 3 . Toughening mechanisms and mechanical properties of the different systems were investigated. Significant improvement in tensile modulus is observed in all composites, depending on filler content. Elongation and notched impact strength were drastically decreased, especially for composites with nano CaCO 3 . Better impact properties were obtained with low content of treated particles, showing the importance of filler treatment.
