Infrared (IR) imaging together with acoustic emission (AE) sensing are employed to follow the progression to failure of graphite epoxy test panels under dynamic loading. Acoustic emission generated by fiber breaks and matrix cracks define the “zero” time for surface observation by an IR camera of the deep heat source from that event. The AE clock and IR clock must be synchronized. The timing of the surface event relative to “zero” permits the calculation of its depth. The position and depth of the IR events can then be related to crack evolution and modeling for failure prediction.
