The bending strength, elastic modules and thermal expansion of different composition of PSZ/Mo composite were measured. Then according to the largest draw stress and stress ratio of it to the bending strength, the optimum component distribution has been enacted by means of finite element analysis. Based on the calculation results, the PSZ/Mo functionally graded materials were synthesized by means of hot pressing method. According to the data from heat insulation experiment, the temperature and stress distribution produced under steady heat insulation was given by finite element analysis. Then the determinate factors of PSZ/Mo functionally graded materials were given.
