Press processing of functionalized flat and tape substructures with a flanged section (A04)

• Subject Area: Plastics Engineering ; Primary Shaping and Reshaping Technology, Additive Manufacturing
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 525069572

A04 investigates the stiffness gradients between long fibre reinforced thermoplastic bulk material (TBM) and infinite (continuous) fibre reinforced thermoplastics (IFRTP) by grading the IFRTP to create a transition zone between the subcomponents. Two grading approaches are investigated: in-line grading by adapting the braiding process and off-line grading by laser treatment. The IFRTP is then over-moulded by the TBM in the press process. The effect of grading on the transition zone will be investigated by mechanical and non-destructive testing. The results will be incorporated into a data-based model to correlate the processing parameters of the transition zone.
