Abstract

A method of repairing a polymeric composite workpiece. The method comprises identifying a localized area of the polymeric composite workpiece having a defect. A plurality of three dimensional interface structures are aligned adjacent at least a portion of the localized area. The method includes applying a polymeric composite patch to the localized area such that the interface structures are disposed between the polymeric composite workpiece and the polymeric composite patch. An alternating electromagnetic field may be introduced to selectively induce localized heating of the interface structures. The localized heating softens regions of the polymeric composite workpiece and the polymeric composite patch adjacent the interface structures, causing the interface structures to penetrate a distance into the respective polymeric composite workpiece and the polymeric composite patch.
