Method of Eddy Current Defect Depth Measurements.

Abstract

This Patent application discloses to a method for nondestructive inspection (NDI) of composite materials comprising conductive fibers. The depth of broken fiber damage in nonmetal matrix composites such as graphite/epoxy and carbon/carbon materials may be ascertained and eddy current inspection is extended to include thick metal sections by this method. Inspection is possible with access limited to a single surface. (JHD)
