Darstellung des Forschungsprogramms

The wide application of active structural parts made for high performance applications requires the development of associated high volume production technologies. At present serial compatible manufacture technologies for the production of active structures with integrated, sensor networks are barely available. Long-Fibre-Injection (LFI) technologies offer an exceptional capability for the realization of such high-volume production processes e.g. for applications in aircraft construction by the possibility for large-scale manufacturing of glass fibre-polyurethane-composites (GPV). For the manufacture of active GPV lightweight structures the conventional Long-Fibre-Injection (LFI) method is enlarged to a Multi-Fibre-Injection (MFI) spraying technology.

Therefore, the systems engineering is enlarged by a novel mixing head to enable a simultaneous and gentle processing of piezoceramic and glass fibres to a piezoelectic functional component. A further focus of the project is the development and implementation of adapted electronic components for the realization of integrated sensor networks to merge the separated production steps sensor manufacture and part manufacture within an efficient manufacture process for the first time.
