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.
