Composite materials (fiber-reinforced plastics : FRP) have been contributed greatly to the weight saving of mechanical apparatus. In the engineering field, since the plate and shell components made by FRP are widely used, the lightweight design is brought to realization. Since FRP materials have different elastic properties depend on the fiber-directions, the vibration characteristics show complex phenomena. In this report, the first, the natural frequencies and natural modes of the slightly curved composite plates formed with angle play are estimated based on the shallow shell theory and the Rayleigh-Ritz method. The next, the influence of fiber-direction and eccentricity of curved plate on the natural frequencies and natural modes are discussed. The third, the prospects of vibration control of anisotropic curved plate with the modern control theory are showed.
