Use of Guided Waves for Detection of Interior Flaws in Layered Materials

The increasing use of composite materials in structurally critical applications necessitates the use of accurate and fast nondestructive evaluation (NDE) techniques. Ultrasonic NDE of continuous fiber reinforced polymer matrix composite materials faces several challenges, including the inspection of highly attenuative thick composites. The ultimate goal of this research is to develop a NDE system that can quickly examine layered composite materials through their entire thickness, yet with greater sensitivity than existing methods
