DEBONDING ANALYSIS OF COMPOSITE MATERIAL USING ULTRASONIC WAVE-BASED NDT METHODS
The article investigates multiple debonding in a glass fibre reinforced polymer structure (GFRPS) using nondestructive testing (NDT) based on ultrasonic guided waves (UGW) propagation. The piezoelectric transducers (PZT) attached to the material excite the UGW and the registered time signals are analyzed. The debonding are in various depths of the GFRPS. It was assessed using NDT-based tools. The presence of debonding and wave scattering based on the depth and location in GFRPS is studied. This is followed by using signal processing methods to visualize and analyze the different characteristics of the ultrasonic waves before and after the debonding. Thus an experimental-based approach to identify the debonding inside the GFRPS and its influence is studied.
