In recent years, the automotive industry has witnessed a growing trend towards the utilization of carbon fiber reinforced plastics (CFRP) for their exceptional mechanical properties and lightweight characteristics. This shift has driven the need for advanced manufacturing processes to meet the demands of high-performance automotive components. This thesis delves into a crucial aspect of CFRP production—carbon fiber towpreg manufacturing, with a specific focus on the influence of post-impregnation zone (PIZ) temperature. The research conducted at the Chair of Carbon Composites (LCC), Technical University of Munich, investigates the impact of varying PIZ temperatures on towpreg characteristics. Mechanical properties, including inter-laminar shear stress (ILSS) and curved beam bending tests, indicate a subtle improvement with increasing PIZ temperature, attributed to enhanced impregnation facilitated by reduced resin viscosity.
