Ultrasonic evaluation of AS4/3501‐6 graphite/epoxy composites and Hercules 3501‐6 epoxies with different curing conditions has been carried out. A differential scanning calorimeter and a dynamic mechanical analyzer were used to characterize the cure status of these materials. The anisotropic elastic moduli, through‐thickness longitudinal wave dispersion and attenuation were measured by different ultrasonic techniques. Effects of curing conditions on the mechanical properties of the composites and corresponding epoxies were discussed.
