This paper reports the preparation of mica-reinforced polypropylene composites by twin-screw extrusion and characterization of various properties. The composites were prepared by the varying weight percentages of the filler up to 40%. Structural identification was carried out by Fourier Transform Infra-red spectroscopy and shifting of few functional groups was noted. Mechanical properties such as stress-strain measurements and impact properties showed minimal interaction between the filler and matrix owing to the difference in morphology of the components. Differential Scanning Calorimetry results showed nucleation by the filler in the composites.
