Abstract
A system and method for making and using a reconfigurable composite part mandrel operable in the manufacture of composite parts. The system may comprise an assembly fixture, a generic mandrel, a reconfigurable simulated skin, a reconfigurable frame portion, and state-changing material operable to harden into a desired configuration for forming a particular composite part. The method of forming and using the reconfigurable composite part mandrel may comprise: inserting the simulated skin within the assembly fixture, inserting or assembling the frame portion within the assembly fixture; inserting the generic mandrel into the assembly fixture; filling a cavity between the generic mandrel and the assembly fixture with the state-changing mixture to encapsulate the frame portion; hardening the state-changing mixture; and removing the assembly fixture and the simulated skin.
