| Popis: |
Test and analysis were performed in a phased approach to study the fatigue and residual strength performance of adhesively bonded repairs to metallic fuselage under a variety of loading conditions and initial damage scenarios. Both boron/epoxy and aluminum bonded patches were used to repair lap joint scribes and through-the-thickness cracks. Various loading conditions were applied, including fatigue under simulated in-service and elevated loads and thermal-mechanical static loading to measure residual strength. During all test phases, damage formation and growth of cracks and disbonds were monitored and recorded using several nondestructive inspection methods. Results revealed that properly designed and installed bonded repairs are durable and effective over long periods of fatigue and exceed typical design service goals of transport category airplanes. In addition, bonded repairs can successfully contain large damage under severe loads in excess of ultimate load requirements. |
