Abstract: A thermo-mechanical property model for composites subjected to fire loading conditions was developed for the purpose of reducing testing time for prediction of the performance of new materials. The thermal diffusivity and conductivity were used to describe the thermal property evolution. A micro-mechanics based model was developed based on visco-elastic foundations for the prediction of rupture behaviour when the samples are compressed, and iso-thermal behaviour. The model was successful in predicting composite life under simulated fire conditions.
