초록

A system for inspecting adhesive in a composite structure, such as for soft or improperly cured regions, includes a transducer and a processing element. The transducer can transmit a signal, such as an ultrasonic signal, into the adhesive such that at least a portion of the ultrasonic signal can propagate through the adhesive, reflect off of an interface between the adhesive and another material, and propagate back through the adhesive. Upon exiting the adhesive, then, the transducer can receive a reflected portion of the ultrasonic signal. Thereafter, t...

1. A method for identifying at least one region of incompletely cured adhesive in a composite structure that includes sections spaced apart to thereby define a gap, and at least partially cured adhesive disposed within the gap to thereby connect the sections, wherein the method comprises:transmitting a signal into the adhesive of the composite structure such that at least a portion of the signal can propagate through the adhesive and reflect back through the adhesive, the signal is transmitted into the adhesive in a direction substantially parallel to an...
