1. A method of fabricating a thermoplastic torque box assembly, the method comprising:
providing a plurality of braided thermoplastic tubular spar caps;
connecting one or more connector elements to one or more of the plurality of braided thermoplastic tubular spar caps;
placing at least one of the plurality of braided thermoplastic tubular spar caps in each corner of an internal torque box tooling apparatus to define a torque box inner portion;
laying up an inner thermoplastic facesheet in a continuous manner around the plurality of braided thermoplastic tubular spar caps to define a torque box structure around the plurality of braided thermoplastic tubular spar caps and to define at least a torque box inner surface;
attaching a plurality of skin panel stabilization elements to the inner thermoplastic facesheet to define four torque box side portions;
laying up and attaching an outer thermoplastic facesheet in a continuous manner around the plurality of skin panel stabilization elements to define a torque box circumference and to form a thermoplastic torque box assembly; and,
heating at an effective temperature and an effective pressure the thermoplastic torque box assembly.
