Corrugated sandwich construction has been recognized as of promising concept for structural design of light transportation systems such as aircraft high speed trains and fast ships. Corrugated sandwich panel can be used as a light weight structure which may reduce effect of vibration if its damping behavior is analyzed. The aim of the present study is experimental investigation of damping properties of composite sandwich panel. Damping properties are determined by using logarithmic decrement method. Also the effect of various parameters on damping properties are analyzed for the optimization of these parameters. The experimental results of natural frequencies and damping ratio are obtained.
