Abstract :
The cymbal design consists of a piezoelectric ceramic disk sandwiched between two truncated conical metal endcaps using epoxy as a bonding agent. The influence of the epoxy bond on actuator performance has been evaluated by manufacturing cymbals with two different adhesives and application methods, manual and semi-automatic. present work, a statistical rupture test has been developed for the study of the electromechanical behaviour of the cymbal piezocomposites. Using the generated charge versus applied force curves, both the effect of the bonding layer and the reliability of this device has been studied and the interpretation of the behaviour of the cymbal piezocomposite during the application of the compression force was established. A bonding layer with lower presence of defects will mean a larger break force. l statistics has been used to describe the variations in the breaking behaviour of the cymbal piezocomposites, and it is employed to predict the maximum operation force.
