Adhesive bonding is one of the methods of joining dissimilar materials which is increasingly commonly used, especially in the automotive and aviation industries. As a part of the final bachelor thesis, we investigated the effect of texture on the surface of the aluminum alloy and composite on the properties of the bonded joints. We determined the process parameters of laser engraving and engraved different shapes of texture on the surface of both materials, performed contact angle measurements and adhesive bonding of samples, and tested the tensile strength of adhesively bonded joints. It was established that the process parameters affect the appearance and quality of the engraving on the surface. With the higher frequency at laser engraving, we achieve a greater depth, a slightly wider line without visible craters. We also found that the laser engraved texture on the surface increases the roughness of the surface and thus, the shear strength of the adhesive bonded joints.
