| Résumé | Flexible ultrasonic transducers (FUTs) which have on-site installation capability are presented for non-destructive evaluation (NDE) and structural health monitoring (SHM) purposes. These FUTs typically consist of a 70 μm thick piezoelectric lead-zirconate-titanate (PZT) composite (PZT-c) coated by a sol-gel spray technique on a 75 μm thick titanium (Ti) membrane. Such an FUT was glued onto a steel pipe of 101 mm in diameter and 4.5 mm in wall thickness and heated at up to 200°C with the glue serving as a high temperature ultrasonic couplant. The pipe thickness measurement accuracy at 200°C is estimated to be 13 μm. FUTs were also glued onto the end edge of a 2 mm thick aluminum (Al) plate to generate and receive predominantly shear-horizontal (SH) plate acoustic waves (PAWs) to detect simulated line defects at temperatures of up to 100°C. FUTs, glued onto a graphite/epoxy (Gr/Ep) composite plate, were also used for the detection of an artificial disbond. An induction type non-contact method for the evaluation of Al plates and Gr/Ep composites using FUTs is also demonstrated. |
