title = "CHARACTERISATION OF EXPERIMENTAL LAMB WAVES PROPAGATION IN CFRP LAMINATES WITH THE METHOD OF WAVELET TRANSFORM",
abstract = "The use of Ultrasonic guided waves such as Lamb Waves has been identified in the last decades as a promising Non-Destructive Testing (NDT) method for defects detection in composites. However, their propagation is complex, especially in Carbon Fiber Reinforced Plastics (CFRP) which are widely used for aerospace structures. Moreover, analyzing the Lamb Waves propagation requires to develop an efficient Signal Processing method to interpret the waves characteristics. In this study, a Signal Processing method using the Wavelet Transform allows to analyze several features of the propagated Lamb Wave: the amplitude, the frequency and the propagation velocity. This study also investigates how these waves features are impacted by different sample parameters such as the thickness, the anisotropy or the presence of delamination.",
