Abstract
Piezoceramic modules offer a great potential for the realisation of smart lightweight components with sensor or actuator functions which are gaining importance in various applications. To transfer these outstanding possibilities from laboratory into mass application, appropriate manufacturing technologies are required. Within the Collaborative Research Center/Transregio (CRC/TR) 39 PT-PIESA technological basics for high-volume production of lightweight components with integrated piezoceramic modules are elaborated. In subproject B6, a novel approach aims at combining the previously separated production steps module manufacture and component integration into a single-stage efficient process. In this paper the development of a spray coat method based on the Long Fibre Injection technology for the integration of novel piezoelectric sensor modules into glass fibre reinforced polyurethane composite structures is introduced. The manufacture of appropriate piezoceramic components as well as development of adapted electronics is presented. Concepts for local embedding of piezoceramic functional elements and suitable electrode structures as well as initial studies for the process-immanent generation of piezoelectric sensor modules are shown.
