Focused NCU Inspection of Ceramic Matrix Composites
Ceramic matrix composites are designed for acoustic isolation, making ultrasonic inspection challenging.
However, Ultran’s high performance non-contact ultrasound transducers and system were able to produce high signal to noise ratio images of ceramic matrix composites and their defects.
The inspection was conducted using focused non-contact ultrasound transducers for high-resolution defect detection. Defects include delamination, programmed core abnormalities of varying sizes, and core structural damage.
