STRENGTH PROPERTIES OF HOLED ALUMINUM ALLOY PLATE REPAIRED WITH CARBON FIBER COMPOSITE PATCHES

To investigate the composite repair effect for damaged aluminum alloy plates, the influences of different composite patches, bonding adhesives, surface treatment methods and repair bonding length on the repaired tensile strength of the holed aluminum plate are studied. The tensile strength of the repaired damaged or corroded aluminum alloy plate used on the planes was tested and the possibility to meet applicable requirements with composite patches was investigated. The results show that the repair methods adopted in the present study are effective.
