  • Method of repairing multiple tube structures and repaired multiple tube structures
    Patent number: 6696174
    Abstract: A method for making a repair to a repair site of a structure made from at least a first tube and a second tube which are joined together with welds. The method includes cleaning and preparing the at least first tube and second tube tubes at the repair site for bonding with composite repair materials. Next, fiber-reinforced polymer composite repair materials are applied to the repair site. These composite materials include at least one elongate, composite tendon strip which is placed on the at least a first tube and a second tube such that the composite tendon strip bridges at least the first tube and a second tube, and a composite strip which is wrapped around and overlays the tendon strip with additional composite strips.
