ABSTRACT:
A hybrid metal/composite spinner cone used in aircraft applications and a method of manufacturing the same. The spinner cone has a metal outer shell which is bonded during the molding process to an inner structural member of thermoplastic composite. The metal shell imparts several desirable characteristics to the spinner cone such as impact resistance, erosion resistance, appearance, and supplying a lightning strike material to protect the composite structure. The thermoplastic composite has significant property advantages over metal or thermoset systems. The hybrid metal/composite spinner cone is manufactured using a ceramic mold which is less expensive and more readily available than a steel mold. The metal shell provides a barrier between the thermoplastic composite and the ceramic mold and allows the finished spinner cone to be easily released from the mold.
