Abstract


The contribution presents a manufacturing technology for the integration of piezoceramic modules into fiber-reinforced thermoplastic parts ready for series production. In regard to the assessment of the integration quality and the damage of the piezoceramic modules nondestructive testing methods like computed tomography and ultrasonic microscopy were used. In the case of acoustic microscopy, a novel 3D-scanning measuring system is introduced, which enables the scanning of curved surface structures. Commercial acoustic microscopes are only designed for investigations of plane surfaces. In order to achieve sufficient results in the image, the ultrasonic transducer axis has to be orientated orthogonally to the specimen surface for every scan position [12]. For this purpose, a 6DoF hexapod robot system is used to perform a matched angle adjustment. Acoustic microscopy is suitable for high-density materials and provides 3D data of the investigated area. The results show that a precise detection of cracks in the piezoceramic layers, trapped air between the fiber-reinforced composite and the piezoceramic modules as well as the localization of conductive paths and electrodes are possible and the ultrasound imaging data show a good accordance to those of the computed tomography.
