Our use cases

Tailored Fibre Placement in TP Composites

Details of use cases

The project focused on material developments and more particularly on hybrid yarns with tailored properties. Demo parts were designed, manufactured and consolidated in a vacuum bagging process. Specific toolings were realised by processes such as incremental sheet forming.


Orientation of fibres according to stress state
Very low weight for high strength


Hybrid yarns


Tailor Fibre Placement, vacuum bagging, incremental sheet forming

Development Status


Development Partners

FGK, Fraunhofer IWU, IPF, Sirris
