  • Patent number: 10913239
    Abstract: One example includes a repair assembly that is comprised of a composite patch, an adhesive, and a veil. The adhesive is disposed between a composite structure that includes an anomaly to be repaired and the composite patch and the composite patch. The veil is disposed between the composite structure and the composite patch. The veil generates heat in response to electric power being applied to the veil, with the adhesive being cured with the heat generated with the veil to repair the composite structure including the anomaly.

  • Patent number: 5731015
    Abstract: Apparatus for manufacturing a composite article comprising an autoclave having a platen, a work tool located in the autoclave and supported by the platen, and a composite article on the work tool. The platen is heated to transfer heat from the platen to the work tool and from the work tool to the composite article to cure that article; and a heat conductive, flexible mat is positioned between the platen and the work tool to maintain a desired thermal conductivity between the platen and the work tool as the work tool is heated.
