Abstract: Present paper improves the dynamic properties of materials like mode shape natural frequency, fiber reinforced polymer compounds by which the material moist is studied with macro mechanical study by same micro mechanical study. For support of an engine, motor, pump or any other mechanical device must be used Structural elements. Here high damping and stiffness is not so easy for mechanical components over vibrated moist that depend on visco elastic nature of material for obtaining all categories of material combinations like damping rubber polymers. Present paper takes 2 compound plates that have a dimension of 140 X 170 mm. one which has a rubber sheet which has inserted in between two carbon fiber sheet layers and others who have only layers of carbon fiber. Modal analysis of two compound plates has performed in ANSYS 19 software to obtain mode shapes and respective natural frequencies of the structure.
