In this study, the thermal conductivity of Sirasu Balloon/Epoxy composites was examined in order to evaluate mechanical and thermal property of the composites in temperature environmental conditions. The matrix resin of the composite is epoxy resin and its dispersion is micro glassy "Sirasu Balloon". The composite system developed is a kind of micro porous materials. A homogenization theory with multi-scale analytical method is described for evaluation of the thermal conductivity of the composites. From the experimental results, we proposed a unit cell model of micro porous materials for Finite Element Method (FEM) analysis. FEM analysis method was described for evaluation of the composite material system in temperature environmental conditions. By using the unit cell model and setting the mechanical and thermal properties of each material at the temperature, some numerical calculations were performed for the mechanical properties and thermal conductivity of composites. Analytical results made good agreement with experimental results in the temperature conditions.
