<p>Composite/metal laminated structures are essential in aerospace engineering, particularly those with hybrid joints that combine induction welding and bolting for enhanced mechanical properties and flexibility. Achieving high-quality drilling in these laminates presents significant challenges. This study integrates experimental and numerical methods to investigate the interfacial damage mechanisms during the drilling of CF/PPS-Al induction welded laminates. A validated heat transfer model was developed to analyze temperature fields and thermal stress distributions. The study systematically examines the effects of drilling parameters on axial force, torque, temperature, and thermal stress. It finds that excessive axial forces are the primary cause of interfacial delamination. Thermal stress concentrates in the PPS resin at the weld seam during drilling, making it prone to damage. Thicker weld seams are more likely to suffer bubble damage, and higher resin content results in greater delamination width. Precise control of drilling parameters is essential to minimize interfacial damage.</p>
