Abstract

Adhesively bonded repair patches are used to extend the useful life of aircraft. Any damage to the repair patch, like the adhesive and cohesive weaknesses similar to that found in adhesively bonded joints, can reduce the expected life of the aircraft. A conventional inspection approach using normal or oblique incidence of ultrasonic waves has only limited capability in detecting adhesive and cohesive weaknesses. An ultrasonic guided wave based inspection method is developed and presented. Aluminum plate with epoxy bonded titanium repair patches were fabricated with simulated interfacial and bulk weaknesses. Defect sensitive guided wave modes were selected and implemented successfully in an angle beam wedge based inspection set-up.
