In the manufacturing of aerospace structures, such as aircraft fuselage panels, ultrasonic welding (USW) is gradually adopted for joining fuselage sections. However, the high-frequency vibrations involved in the USW process can sometimes induce defects at the welded locations due to uneven energy input, causing non-uniform heating, material degradation, fiber misalignment, or void formation at the weld interface. Detecting these defects is essential for maintaining structural integrity and reliability.
The present project focuses on inline monitoring of ultrasonically welded thermoplastic composites (CF/PPS) to ensure the production of defect-free structural components, thereby improving the safety and extending the service life of aerospace structures.
