Abstract

The purpose of this work was to study the influence of microstructure on effective transverse thermal behavior of unidirectional silica fiber reinforced composites with carbonized phenolic resin matrix. The randomly distributed fiber model is firstly established and then the temperature dependent thermal conductivity of silica fiber and phenolic matrix is taken into account for predicting the effective thermal conductivity of composite. Results provided by finite elements simulations for the silica/phenolic composite of interest have shown that the random model can give closer predictions to the theoretical results from Maxwell model.
