Induction welded thermoplastic torsion box
We used Automated Fiber Placement to manufacture optimized spars and skins & to layup flat blanks, that were Direct Stamped® to produce ribs and stiffeners. The stiffeners were assembled by co-consolidation, while the consolidation of the skin, to obtain a self-stiffened skin. The parts were assembled by induction welding to obtain a closed box.
Raw material used : UD fibers & LM-PAEK matrix

Why and Whom
Daher supplies thermoplastic parts for aerospace and induction welding machines (KVE Composites B.V.), so our goal is to be able to design and certify TP welded subassemblies, which provide added value compared to state of the art fastener assembly. Targeted parts are torsion boxes.
