The paper presents a study on the relationship of the maximum deflections and fre-quencies of the fundamental tone of transverse oscillations of a number of composite two-layer plates of a round shape, rigidly pinched and pivotally supported on the contour. In the course of work we determined the maximum deflectionW0 from the action of the static load and the natural oscillation frequency  of the composite plates. We defined the proportio-nality coefficient K. According to the results, we designed the graphs of the maximum def-lection change and the frequency of natural oscillations when changing the thickness of one layer of the composite plate.
