This program was undertaken to develop and test wing design manufacturing and fuel sealing concepts that will eliminate the need of mechanical fasteners to attach the lower wing cover to the substructure. In addition, the ability to remove and reseal the thermoplastic bonded joint was demonstrated. The integrally cured Wing Cover-To-Spar Concepts have demonstrated great potential to reduce cost, increase structural efficiency, increase fuel sealing reliability and improve damage tolerance. Integral to this program was the development of analytical and fabrication techniques for translamina reinforced Wing Cover-To-Spar joints. The test wing box has successfully demonstrated the ability of a stitched and thermoplastically sealed lower wing cover to resist wing torsion and pressure loads both statically (RT and 270 F) and in fatigue (RT and 270 F). This volume reports the coupon designs, coupon manufacturing, coupon moisture conditioning, coupon test results, test box design, test box manufacturing, test box thermoplastic sealing and test box static and fatigue test results.
