Non-Destructive Testing Methods for Detecting Red Plague Within an Insulated Silver Plated Copper Conductor

DAngelo Technologies, LLC (D5T) successfully conducted research to develop non-destructive test equipment and procedures for detecting Red Plague within an insulated silver plated copper conductor. Red Plague is an embedded fault and the consequences of Red Plague formation compromises the integrity of both the electrical and mechanical properties of the wiring system often resulting in wholesale replacement of wire and harnesses, mission abort, or mission failure. The presence of Red Plague is often not located until stored wire is stripped during installation, repair or replacement. Visual inspection for Red Plague is not consistent and is very subjective, especially if the Red Plague is found at the ends of the wire and the extent of Red Plague within the length of the wire is unknown. This Phase II SBIR presents a path to prototypes of three NDT methods for detecting Red Plague within conductors. Approved for Public Release | 16-MDA-8951 (15 December 16)
