Introduction of the Research Group
The main aim of the research group is to create a comprehensive technological and modeling background for the novel hybrid TCM (thermoplastic composite material) process. In the project, the researchers characterize the polymerization kinetics, crystallization kinetics, and viscosity of the in situ polymerized thermoplastic for numerical modeling of the injection molding, 3D printing, and T-RTM (Thermoplastic-Resin Transfer Molding) processes. Reinforcement structure development is in focus regarding short and long fibers, such as conventional and 3D printing-based preform technologies for the designable load-bearing structures. Overmolding and overprinting will be further developed as conventional T-RTM technologies are limited in geometries.The group focuses on the numerical modeling and recyclability of these polymers, composites, and hybrid composites. Besides the advanced methods, the research group is also responsible for injection molding and its development, including simulations, sensor technologies, and material development.
