The effect of temperature environmental condition on the mechanical behavior of basalt fiber reinforced polymer (BaFRP) composites is investigated. Basalt fiber made from basalt rocks is one of the eco-friendly materials. From the experimental results for Ba/Phenol composites, the laminate kept in high temperature condition has lower tensile strength and equivalent Young's modulus than that in the room temperature condition of 298K. It is revealed that the diameters of basalt fiber manufactured vary widely and the stochastic consideration might be needed in order to predict the mechanical properties of Ba/Phenol composites theoretically. By using a model for microstructure of the composites, a homogenization theory with multi-scale asymptotic expansion is adopted to examine the macro- and microscopic behavior of the composites in the environmental conditions theoretically.
