Energieeffiziente Herstellung und mechanismenbasierte Charakterisierung des Korrosionsermüdungsverhaltens von laserstrukturierten Hybridverbunden

The research project aims to produce energy-efficient hybrid components made of laser-structured aluminium alloy 6082 and epoxy resin-based CFRP prepreg, in which the two components are formed and joined together in a single step. This makes the manufacturing process more efficient, as further joining processes, such as bonding, can be omitted. A parameter study will first be carried out using plate-shaped hybrid samples to investigate the adhesion and corrosion properties and determine the best combination of parameters for the laser pre-treatment and the curing process. The resulting parameter set should then be transferred to producing real component-like geometry, e.g. hat profile. For this purpose, a pressing tool will be developed adapted to the material properties of fiber-reinforced plastics. Finally, the manufactured hat profiles will be examined for their dimensional accuracy, mechanical properties, corrosion and fatigue properties.
