Paper Abstract

This paper describes some initial results of an evaluation technique, applied to composite plates, which effectively measures the ultrasonic transfer function of these plates and interprets these transfer functions in terms of damage thresholds within the material samples. The samples are probed using Lamb waves at frequencies in the region of 250 kHz. The detectors are interferometric optical fiber systems embedded within or mounted on the surface of the sample. The system is sufficiently sensitive to detect damage and/or structural deterioration before its magnitude is sufficient to compromise structural integrity.
