Repair of advanced composite structures

This paper presents the concluding results of the large area composite structure repair program in which five large panels were repaired and subjected to static tests. A description of the Northrop bonded-cocured scarf joint repair is given with a review of strength and durability test results. Application of this technique to the problem presented in each of five panels is discussed. Finally, the repair of a speedbrake damaged in service is described. Repairability of advanced composite structure is fully demonstrated.
