Advanced Quality Assurance Techniques for Innovative Materials

Ultrasonic non destructive inspection of composite materials is a particularly effective technique for the quality assurance of the material structure. Such characterization is useful both to know material conditions before destructive testing procedures and to evaluate composite products either before or during service in an absolutely nondestructive manner. In this seminar, the principal techniques utilized to obtain, interpret and display ultrasonic infomation, with special reference to digital signal processing, are discussed and illustrated by experimental examples shown through the aid of a video tape.
