<p>Systems and methods for detecting discontinuous fibers in composite laminates are disclosed. In one embodiment, a method includes transmitting an incident ultrasonic signal onto a front surface of a composite laminate at a plurality of locations over an area of interest, receiving a full waveform at each of the plurality of locations over the area of interest, storing the full waveform at each of the plurality of locations over the area of interest, and analyzing the full waveform at each of the plurality of locations over the area of interest for an amplitude distortion indicative of a fiber discontinuity within the composite laminate, including selecting a gate value corresponding to a depth location within the composite laminate and displaying a C-scan image of an amplitude value from the full waveform at the plurality of locations over the area of interest.</p> |
