The effect of fiber orientation on the thermal expansion coefficient, the Young's modulus and the thermal conductivity of hot pressed Mo/PSZ composites was studied both experimentally and theoretically. The fiber orientation of the hot pressed Mo/PSZ composites was determined by optical microscopic observations on their cross-sections. In order to make a theoretical analysis of the above mentioned properties on the basis of Eshelby's equivalent inclusion method, the measured fiber orientation distributions were converted to polynomial functions. Compared with the conventional procedure using cosine or uniform distribution functions for the fiber orientation, the polynomial distribution function gave predictions which were in good agreement with the experimental.
