Multimodal characterization of adhesion within thermoplastic welded composites using Lamb waves

The characterization of interfaces within assemblies using non-destructive methods is a subject of interest for both academic and industrial purposes. Most of the work and methods developed are based on qualitative approaches, often designed to characterize bonding. When it comes to quantitative adhesion characterization, the number of studies remains limited. This contribution presents results related to the characterization of the adhesion of thermoplastic composite welded assemblies. For this
