ULTRASONIC GUIDED WAVES FOR HEALTH MONITORING OF HIGH PRESSURE COMPOSITE TANKS

Ultrasonic guided wave modes are proposed to control the integrity of high‐pressure composite tanks produced by EADS—ASTRIUM, France. The purpose is to demonstrate the potentiality of air‐coupled transducers to set‐up a contact‐less, single‐sided technique for testing the moisture content and/or the micro‐cracking of carbon epoxy composite wound around a Titanium liner.
