Abstract
An ultrasonic nondestructive system and method for monitoring resin cure during composite sheet material fabrication is described which comprises a first transducer for directing a plurality of ultrasonic pulses of preselected pulse frequency along a selected propagation axis onto a first surface of the material during the curing of the resin, a second transducer near the second surface of the material for receiving transmitted pulses and for providing output signals characteristic of the transmitted pulses, and electronic signal processor and display equipment responsive to signals from the second transducer for analyzing the signals and providing output corresponding to the amplitude and duration of the transmitted pulses.
