Abstract
A method of isolating a metallic fastener from a carbon-fiber composite panel includes inserting the metallic fastener within an electrically isolating annular collar; inserting the metallic fastener and electrically isolating annular collar within a hole defined by the carbon-fiber composite panel; and securing the metallic fastener to the carbon-fiber composite panel. The annular collar may be circumferentially disposed about the metallic fastener such that the annular collar separates and electrically isolates the entire metallic fastener from the carbon-fiber composite panel. As such, the annular collar may minimize the galvanic reaction between the fastener and the carbon-fiber composite panel.
