This work deals with a novel processing method that combined extrude with laminate molding for preparing polymeric graded material (PGM). The variations of inhomogeneous property were generated by altering the feeding speed and/or weight ratio of the components as well as changing the order or numbers of the folded layers. Three modes of polypropylene (PP)/ talcum powder (talc) flat PGM (signed with T1, T2, T3) are fabricated successfully by using this new technique. The preparation, structure and property of the resultant PP/talc graded composite were investigated. Results indicate that the composition, morphology and properties show a gradient variation along their thickness direction of the flat PGMs.
