This study discusses validation of an identification method of material properties of a single layer CFRP thin plate. This identification method is a method to select material parameters to match the vibration characteristics of the experiment and the vibration characteristics of the analysis. In the method, the Ritz method calculates vibration modes and natural frequencies of thin CFRP plate using material parameters which are selected by differential evolution method (DE). Some simulation data are used to probe the validity of the identification method. This method was able to identify the orientation angle of CFRP plate and elastic coefficients. Identification of Poisson's ratio had a large error. In the case of experimental data, the method could not identify difference orientation angle of the plate correctly. This seems to be because the torsional mode of vibration has some errors in the experiment.
