Laser structuring offers the advantage that it is a low-wear and thus almost maintenance-free process. The process duration depends on the scanning speed of the laser and the area to be processed. A bonded joint subjected to shear loading has an uneven shear stress distribution: stress peaks are particularly present in the edge areas. This reveals a possibility to reduce the process time by laser structuring only the areas under shear stress peaks. In this study, partially laser-structured and bonded joints of a steel and a carbon fibre-reinforced plastic (CFRP) were investigated regarding their adhesion properties.
