Abstract: This paper describes the investigation of a compression molding process for the production of a battery housing structure made of glass mat reinforced thermoplastic (GMT) for electric vehicles. The battery housing structure was scaled to a demonstrator geometry in the form of a battery shell. To enable variant-flexible manufacturing, a modular forming tool was used, which can be modified by interchangeable inserts. The process chain involves the heating of the GMT, the transfer to the isothermally heated forming tool and the compression molding. The influence of various process parameters such as stamping force, stamping speed, GMT temperature and the GMT quantity on the mold filling were experimentally and numerically investigated. Finally, the results were transferred on different geometries where a complete mold filling was achieved.
