- Abstract
With reference to the challenges in the automotive industry like fuel economy or weight reduction, new hybrid materials are being developed and applied for established as well as new components. One approach to achieve less weight while retaining adequate mechanical characteristics is the combination of different materials [1, 2]. In [1] the advantages of hybrid structures consisting of fibre reinforced plastics (FRP) in combination with sheet metal inlays are investigated. For the manufacturing of these FRP-metal structures new innovative production concepts are needed. The present contribution deals with FE based process design of the manufacturing process for hybrid components with nonkinematical knitting rotation. Within the process, the metallic inlays will be entirely wrapped by the thermoplastic matrix. Using this method, a form- and material fitted structure is generated by process integration. Air locking defects can be suppressed by the rotational tool motion through an improved local contact pressure. Applying a rotational motion influences the flow direction and fibre orientation in positive manner. An extensive material characterization has been carried out. In order to describe the flow behaviour of the polymer component, viscosity data is needed. Therefore, experimental investigations are carried out and provided for the FE simulation.
