Paragraph starter
The experimental investigation by Cetin (2022) into tensile strengths of single-lap joints revealed that hybrid joining techniques, combining adhesive bonding with mechanical fasteners like rivets, significantly outperform purely adhesively bonded joints. Specifically, a bonded/4-riveted joint demonstrated a 5.7-fold increase in tensile strength compared to an adhesively bonded joint, highlighting the potential for enhanced structural integrity in applications involving dissimilar materials such as aluminum and composites.
