Composite Repair of Cracked Aluminum Structure,
Abstract
This paper discusses the use of bonded composite patches for repair of a wide range of typical fatigue cracked and otherwise damaged aluminum structural panels. Experimental data on stress intensity and crack growth characteristics were obtained to evaluate the advantages of such repairs. A range of metal thickness and patch parameters (thickness, orientation, bonding temperature) were tested. Edge crack 4 inch by 18 inch 2024T3 aluminum panels were patched and fatigue behavior evaluated under constant amplitude and the Falstaff flight spectrum loading. The results showed panel thickness and fatigue test load spectrum to be important parameters.
