Characterization of Glued Bonds Using Ultrasonic Reflected Beam
Adhesive bonds of laminates of metal and polymer have been extensively studied using ultrasonic techniques. The strength of the bond is of primary importance and many studies have been aimed at deducing this property from ultrasonic measurements. The quality of adhesively joined structures is mainly determined by two types of factors: i) the cohesive strength of the glue ii) the adhesive strength of the metal-glue interface. To address the last type, several ultrasonic techniques using mainly plate and interface waves have been recently considered [1–4]. Their main advantage, compared to longitudinal or shear waves, is that they are very sensitive to the interface conditions.
