Research on ultrasonic non-destructive examination in water immersion of a composite material

摘要

Nondestructive Evaluation is important in particularly for the control of composite parts. Critical parts are required more and more to be tested during the manufacturing process by more efficient and accuracy nondestructive evaluation methods (NDE). One of the most suitable method to be automated is the ultrasonic exam. Inspections with this technique over composite parts introduces additional difficulties to the standard inspection, because the acoustic coupling it can't be done correctly. In this paper, we present a method of examination with ultrasound, for a composite part.
