A method for manufacturing a structural component of a blade segment for a rotor blade includes providing a mold of the structural component having an outer wall that defines an outer surface of the structural component. The method also includes laying up one or more fiber layers in the mold so as to at least partially cover the outer wall. As such, the fiber layer(s) form the outer surface of the structural component. Further, the method includes providing one or more metal mesh layers having one or more ends. Moreover, the method includes providing a cover material to the end(s) of the metal mesh layer(s). In addition, the method includes placing the metal mesh layer(s) with the covered end(s) atop the fiber layer(s). Thus, the method includes infusing the fiber layer(s) and the metal mesh layer(s) together via a resin material so as to form the structural component.
