Light weight structure made of fiber reinforced plastics (FRP) is manufactured by several forming types. In this study, circular cylindrical shells are formed by FW forming unit which has been designed by this lab.. Natural frequency and mode measured by the modal test are compare to the analytical result based on homogeneous method. The result shows the simply supported condition (SS) setted in this test is convenient for measuring vibration characteristics as the natural frequency and mode.
