Study on the coupling phenomenon between transverse bending and in-plane stretching for antisymmetrically laminated plates or shells about the middle plane has been discussed. However, there is little theoretical and experimental studies to deal with the coupling effect of Filament-Wound(FW)formed shells on vibration characteristics. The purpose of this paper is to show the influence of coupling effect on natural frequencies of FW formed cylindrical shells simmply supported at both ends for parameters of material anisotropy, winding angle(α)and the number of layers(N). Firstly influencies of E_<11>/E_<22> modulus ratio, shell geometry and lamination construction on the coupling effects for cross-ply laminated shells are studied. Secondly influencies of winding angle(α)and vibration mode(m, n)on coupling effects for angle-ply laminated shells are studied.
