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.
Highlights
Among the previous rare works, plasticity theory combining with experiments often focus only on steel materials, aluminum and some research on composite materials, polymer
The article focused on studying the effects of temperature parameters to the forming ability of composite plates, finding out the limited forming angle according to temperature

Summary
Among the previous rare works, plasticity theory combining with experiments often focus only on steel materials, aluminum and some research on composite materials, polymer. The study of theory and simulation for composites, thermoplastics have established the influence model of tool size ratio, the size of depth step[1], "Incremental Forming for the thermoplastic glass materials"[2], "SPIF in processing polymer materials"[3]. The short and long fibers are typically employed in compression moulding and sheet moulding operations These come in the form of flakes, chips, and random mate (which can Science & Technology Development, Vol 14, No.K2- 2011 be made from a continuous fiber laid in random fashion until the desired thickness of the ply / laminate is achieved). For these features, the short-fibers composite has the ability of deformation larger than the others. Tool is moved along the circular toolpaths, down step is 0.5mm and the down distance total is 20mm
