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