Abstract: The application of fiber-reinforced thermoplastic mono-material sandwich panels has many advantages such as recyclability, reduction of processing cycle times, integration of additional elements by means of welding and possible in-line production. The manufacturing process window of the welded sandwich panels is limited by two phenomena. On the one hand, the temperature at the skin-core-interface shall exceed the melting point in order to achieve the sufficient bonding quality. On the other hand, the core shall not be overheated and overloaded to avoid its collapse.
The main challenge in this work was to analyze and compare the bonding degree theoretically and experimentally. Based on the microscopic analysis, the difference in the bonding formation of the several manufacturing methods was observed. Furthermore, the effectiveness of the determined processes and its relation with the bonding degree was evaluated.
