1. A method of repairing a defect in a polymeric composite structure, the method comprising:

  • applying a pre-polymer solution comprising a reinforcing material, a monomer, and at least one of an initiator or an activator to the defect in the polymeric composite structure;

    disposing a thermally conductive support structure on a first surface of the polymeric composite structure over at least a portion of the defect having the applied pre-polymer solution; and

    applying heat through the thermally conductive support structure to the pre-polymer solution to induce polymerization of the monomer and to form a repaired region in the polymeric composite structure comprising a polymer having the reinforcing material distributed therein,wherein the thermally conductive support structure facilitates a smooth, continuous surface between the first surface of the polymeric composite structure and the repaired region, andwherein the polymerization of the monomer is facilitated by the heat and at least one of the initiator or the activator.
