Abstract: A method is disclosed for repairing a worn helicopter rotor blade made of composite materials by adhesively securing a supplemental leading edge abrasion wear strip made of nickel to the leading edge of the rotor blade. The periphery of the bonding surface of the leading edge of the rotor blade is masked. The bonding surfaces of the supplemental leading edge strip and the rotor blade are cleaned with a medium-grit scrubbing pad, grit-blasted with aluminum oxide and then rinsed with DI water. A strip of a structural adhesive film is hot bonded to the bonding surface of the supplemental leading edge strip using vacuum and a high temperature oven cure. The side of the structural adhesive film bonding surface which will be secured directly to the rotor blade bonding surface is first abraded and then wiped with a solvent. An epoxy adhesive mix is applied to the bonding surfaces of the rotor blade and the structural adhesive film of the supplemental leading edge strip.
