Patent ID: 7467052

Claim:
A method of performing an ultrasonic inspection of a composite laminate, comprising: transmitting an incident ultrasonic signal onto a front surface of the 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 wrinkle 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, wherein the composite laminate further includes a back surface opposite from the front surface, and wherein receiving a full waveform at each of the plurality of locations over the area of interest includes receiving a full waveform of amplitude versus time between the front and back surfaces of the composite laminate at each of the plurality of locations over the area of interest.
