Multi-Stage Filament Winding

COMPLEX SHAPED FIBRE COMPOSITE COMPONENTS FOR THE CONSTRUCTION INDUSTRY PRODUCED USING THE FILAMENT WINDING PROCESS

The filament winding process reliably produces high-quality components from fibre reinforced polymers (FRP) and is applied in the fabrication of series products with high quantities. The spectrum of possible geometries is limited to rotationally symmetrical components. Currently, component sizes ranging from small round tube cross-sections to aircraft fuselages are being realised.

The aim is to apply the classic filament winding process at large individual pieces. This enables the production of FRP components for the construction industry. The core material is environmentally friendly and reusable. Multi-stage winding cores enable an expansion of the range of shapes to include double-curved and undercut geometries. With these possibilities, the application potential of load-bearing FRP components in the building industry can be drastically increased.

For the industrial production of complex shaped prototypes made of fibre-reinforced polymers, the multi-stage filament winding process is to be investigated on a larger scale for the first time. To this end, an industrially applicable process is to be developed with which it will be possible to use multi-part winding core structures to produce geometrically complex, load-bearing components for the construction industry in small quantities. The core material used is to be recovered after production of the component.
