Abstract

A method of nondestructively identifying regions "R" of high density in a substrate (10) of a bonded matrix of carbon fibers by resistively heating the substrate and taking an infrared image of the heated substrate. Terminals 12, 14, 16 and 18 are connected to a power supply 26 by wires 22 and cable 24 of which they are a part, to effect the heating.
