ABSTRACT The present invention relates to a reinforced polypropylene composition comprising a polypropylene component (a modified polypropylene or a mixture of said modified polypropylene and an unmodified polypropylene), an ethylene-propylene copolymer, a glass fiber and mica having an average particle diameter of 40-160 µm and an average aspect ratio of 30-85. This composition can provide molded articles of very low warpage and is useful for the production of molded articles, particularly core materials of instrument panels for automobiles requiring high rigidity, high heat resistance and deformation resistance.
