  • Device and method for non-destructive ultrasound inspection of structures made of composite material
    Patent number: 10641738
    Abstract: A device and method for detecting delamination in a panel of laminated composite. The device comprises an ultrasonic probe with a plurality of elementary transducers, an electronic device in communication with the elementary transducers, and a display device. The transducers emit an ultrasonic pulse and receive a pulse reflected by an element in the panel. The received pulses are grouped into clusters of healthy, or non-damaged, zones and damaged zones. The dimensions of the damaged zones are based upon the limits formed by healthy zones. A display of the defect with dimensions is produced on the display device. A scale image of the defect with dimensions, via paper or digital overlay, can be placed on the panel.
