DEFORMATION ABILITY OF SINGLE POINT INCREMENTAL FORMING FOR THEMO-PLASTIC COMPOSITE MATERIALS

th , 2010, Manuscript Revised January 21 st , 2011) ABSTRACT: The studies of theory and simulation for composite materials have not yet built model for analyzing the effects of temperature's influence on the deformation ability of these materials. The article focused on studying the relationship between temperatures and deformation ability of composite sheets in SPIF method, building and analyzing simulation model, determining the limited deformation angle according to the temperatures and building the chart of limited forming for the polypropylene (PP) glass fiber type E mat composite material.
