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 graphiteepoxy and carboncarbon 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
