Conventional ultrasonic C scan used to detect flaws in graphite/epoxy composite panels modified to enhance sensitivity to transverse cracks. Modification involves reorientation and repositioning of ultrasonic transmitter and receiver to take advantage of mode-conversion phenomena at interfaces between liquid couplant and panel to be probed. Angle of incidence chosen so only shear waves propagate obliquely through panel. Although mode-conversion equations solved to take full advantage of technique somewhat complicated, they are straightforward, and technique implemented easily in practice.
