Analysis of the Possibility of Forming Stiffening Ribs in Litecor Metal-Plastic Composite Using the Single Point Incremental Forming Method

Efforts to reduce COx are extremely important, which forces the use of materials and technologies that weight means transport in order energy consumption. Currently, aluminum alloys FRP composites still too expensive for mass industry applications. Presented this study, Litecor is a three-layer composite combines high strength steel with low density plastic. Thanks external covers 0.3 mm thick light core 0.7 thick, stiffness was achieved while maintaining relatively weight. The reduction comparison blanks same up 40%. mainly developed by ThyssenKrupp, it promising construction material, but requires development technology forming joining. In possibility layered investigated using single-point incremental sheet (SPIF) method. As part research, stiffening ribs were shaped, maximum depth embossing determined. degree thinning selected cross-sections influence rotational speed tool feed rate on properties shaped surface also analyzed. Incorrectly shaping parameters have been shown damage zinc coating inner embossing.
