Abstract : Surface defects in composite and adhesively bonded structures that penetrate to a metal substrate are detected by applying a solution of 8-hydroxyquinoline to a surface of such a structure and viewing the surface under ultraviolet light. The presence of a flaw or crack leading from the surface to the metal substrate is indicated by a fluorescent glow. (Author)
