METHOD AND APPARATUS FOR FORMING A COMPOSITE FUSELAGE STRUCTURE

Abstract:

A method and apparatus for forming a composite structure. An inner tooling, a stackup, and an outer tooling are held in place together using a load constraint. A bladder and a plurality of stringer bladders in the stackup are pressurized to cause expansion of the bladder and the plurality of stringer bladders, thereby pushing together an overbraided thermoplastic skin and a plurality of overbraided thermoplastic members in the stackup. The overbraided thermoplastic skin and the plurality of overbraided thermoplastic members are co-consolidated while the bladder and the plurality of stringer bladders are pressurized to form the composite structure.
