Abstract
The thermal response of a fiber reinforced polymer composite was measured by the bench-scale Cone Calorimeter and Intermediate-scale Calorimeter (ICAL) fire experiments. Finite-rate and infinite-rate pyrolysis models were used to predict the response of the composite panels under the same thermal boundary conditions as in the fire tests. It was shown that both models can give acceptable temperature, mass loss, and effective char thickness predictions. The effect of internal gas convection on thermal response predictions was determined insignificant at low heat flux levels. The thermal insulation at the back surface of the composite panel significantly increased both temperature and mass loss predictions.
