Profiles of Fatigue Damage in Graphite/Epoxy Composites from Ultrasonic Transmission Power Spectra /

Early fatigue damage in non-unidirectional multi-ply graphite/epoxy composites is manifested by a distribution of cracks and disbonds through the bulk of the material. Such damage is subtle and is difficult to detect with conventional ultrasonic technology. Consequently, a new ultrasonic measurement...
