Abstract
Ten samples of composite panels were evaluated in the smoke chamber using a high flux heater to produce heat flux heater to produce heat flux levels up to 9.5 W/cm(2). This study demonstrated the potential of this apparatus as a means of evaluating ignitability as well as smoke evolution. Depending on the material and the heat flux level, ignitability results ranged from ignition within 2 sec to no ignition during the test period. Smoke density generally increased with increasing heat flux. A composite panel consisting of bismaleimide-fiberglass/bismaleimide honeycomb with carbon microballoons exhibited the lowest smoke density at high heat flux levels and the greatest resistance to autoignition.
