Master Thesis: »Modeling of heating processes for mono-material sandwich panels«

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research units throughout Germany and is a leading applied research organization. Around 32 000 employees work with an annual research budget of 3.4 billion euros.

At the Fraunhofer IPT in Aachen, we work with more than 530 employees every day to make the production of the future more digital, more flexible and more sustainable. In the group »Laser System and Heating Technology«, we design and construct various prototype machines for laser-based and laser-assisted processes.

Within the scope of your thesis, you will develop the laser-assisted heating processes for recyclable mono-material sandwich panels (MMSP). A numerical model will be developed to describe the transient temperature change along the thickness direction of MMSP during the heating process, in which both laser and IR radiation are used to heat the surface layers and foam core of MMSP to different temperatures. This increases the formability of the MMSP without causing the foam structure in the core to collapse. The model is experimentally validated by a real heating process of MMSP with temperature measurement at several locations. The model validation experiment is developed and carried out for this purpose. In addition, a virtual parameter study is carried out based on the process model in order to investigate the influence of process parameters on the temperature distribution. Based on the parameter study, a model-based control system for MMSP heating is developed.
