In lightweight construction, integrated piezoelectric sensors and actuators find application for structural health-monitoring, vibration control, reduction of noise emission and condition monitoring. In order to create such smart components, we embedded piezofiber composites into thermoplastic structures. Thermal and mechanical loads during the integration process can lead to partial depolarization and thus degradation of the piezoelectric properties. In the present work, we investigate the effect of the integration on the poling condition and polarizability of piezofiber composites.
