Abstract
The cure state of a mass of a curable material, such as a composite material formed of a fiber embedded in a curable polymeric matrix, is measured. At least two wire segments are embedded into the mass, and an ultrasonic signal is propagated through the wire segments. From the ultrasonic propagation characteristics, the cure state of the mass is determined.
