Validation of the FEA of a Sheet Metal Forming Process of Composite Material and Steel Foil in Sandwich Design

Abstract:

A multi-material concept in sandwich design using two steel foils and continuous fiber-reinforced thermoplastics represents a promising structural approach to the production of hybrid parts. This contribution deals with the experimental and numerical analysis of a conventional sheet metal forming process using a composite material based on Polyamide 6 (PA6) with unidirectional endless glass fiber reinforcement and HC220Y+ZE steel foil. A unidirectional composite plate is positioned between two steel foils in sandwich design and formed into the hybrid part under appropriate temperature conditions. Afterwards, the forming process is analysed numerically with the software LS-DYNA and for verification of the FEA the geometry of the hybrid part is measured optically with ATOS system of the company GOM.
