INDUCTION CONSOLIDATION FOR WIND BLADE FABRICATION

A method of fabricating a thermoplastic composite tubular structure (10) for use as a wind turbine blade (10) is presented using a combination of induction heating with smart susceptors (24, 26) to consolidate a wrapped mandrel (3). The method can include overbraiding the mandrel (3) with a continuo...

Zusammenfassung:	A method of fabricating a thermoplastic composite tubular structure (10) for use as a wind turbine blade (10) is presented using a combination of induction heating with smart susceptors (24, 26) to consolidate a wrapped mandrel (3). The method can include overbraiding the mandrel (3) with a continuous fiber thermoplastic composite material (6) to form an overbraided mandrel (8) that is then installed in a ceramic induction oven where the mandrel (3) is pressurized internally to consolidate the thermoplastic overbraid during heating
