Air-Coupled Lamb Wave Testing of Buried Air-Voids in Foam-Filled Sandwich Panels

Sandwich panels, composed of two steel faces and a rigid foam core, are an inexpensive and lightweight option for construction industry. However, voids can form in the foam core during the manufacturing process. This paper uses ultrasonic testing to detect such voids in the foam core of sandwich pan...
