Abstract : The vulnerability of electronic equipment to damage by carbon fibers released from burning aircraft type structural composite materials was investigated in a shock tube facility. Tests were conducted on commercially available stereo power amplifiers which showed that the equipment was damaged by fire released carbon fibers but not by the composite resin residue, soot and products of combustion of the fuel associated with burning the carbon fiber composites. The limited testing indicated that the failure rates of the equipment exposed to the fire released fiber were consistent with predictions based on tests using virgin fibers.
