A laminated composite cylindrical shell made of CFRP was excited horizontally under a clamped-free condition. After the prepreg was wound onto a mandrel in the five layers cross-ply laminate, the shell, which was formed by the autoclave, was partially filled with water. The Simulink of MATLAB was applied for excitation to generate white noise, which was led to the controller of exciter. The optical fiber sensor was used to detect the displacement of the cylindrical shell wall. FFT analyzer to determine the resonance frequencies and vibration modes analyzed exciting acceleration and response function of displacement. Signals of vibration were processed with personal computer. Modal analysis of vibration was carried out by STAR-System. It was found experimentally that the inside liquid level affected the displacement response of shell wall.
