Abstract In a collaborative effort, the Federal Aviation Administration (FAA) and the Boeing Company are assessing bonded repair technology of composite panels representative of transport airplane wing structure through test and analysis using the FAA’s Aircraft Beam Structural Test fixture. Emphasis has been placed on investigating methods and tools used to conduct analysis and predict structural performance of bonded repairs and those used to monitor and evaluate repair quality over the life of the part. The initial baseline phase of the program verified analysis models and provided an initial reference point for inspection and monitoring systems used to detect and track damage formation. Recent second-phase efforts support bonded repair size limit (BRSL) studies and methods used to predict the limit load residual strength for a failed scarfed repair in solid composite laminates. In general, methods under development for BRSL residual strength predictions correlated well with test results.
