Hybrid Thermoset and Thermoplastic Composite Airplane Wings Employing Thermoplastic Co-Bonding

An airplane wing, comprising:

• a wing substructure including a composite front spar, a composite rear spar and a plurality of composite ribs extending between the composite front spar and the composite rear spar;
• an upper wing skin assembly including a composite upper wing skin and a first plurality of composite stringers co-bonded to the composite upper wing skin by a thermoplastic bonding film that has a melt temperature less than a glass transition temperature of the composite upper wing skin and the first plurality of composite stringers, wherein the upper wing skin assembly is co-bonded to the wing substructure by a thermoplastic bonding film that has a melt temperature less than a glass transition temperature of the wing substructure;
• and
• a lower wing skin assembly including a composite lower wing skin and a second plurality of composite stringers co-bonded to the composite lower wing skin by a thermoplastic bonding film that has a melt temperature less than a glass transition temperature of the composite lower wing skin and the second plurality of composite stringers, wherein the lower wing skin assembly is co-bonded to the wing substructure by a thermoplastic bonding film that has a melt temperature less than a glass transition temperature of the wing substructure.
