    Abstract: Disclosed herein is a method of repairing a composite structure comprising fiber-reinforced polymer plies each with unidirectional fibers. The method comprises removing a damaged portion of the composite structure to form a void in the composite structure. The method also comprises positioning an adhesive layer into the void. The method further comprises positioning a first nanotube sheet ply and a first fiber-reinforced polymer repair ply into the void, by first positioning one of the first nanotube sheet ply or the first fiber-reinforced polymer repair ply into the void over the adhesive layer. The first nanotube sheet ply is fiberless and the first fiber-reinforced polymer repair ply comprises unidirectional fibers.
