The stress distribution of anisotropic multilayer filament-wound composite pipes was analyzed. Based on the three-dimensional anisotropic elasticity and the classical laminated-plate theory, exact elastic solutions of stress and deformation were presented for the filament-wound pipes subjected either to internal pressure, axial force or torsion. The shear coupling effect is considered in the analysis. The influence of winding angle and winding sequence on stress distribution in pipes was investigated. The ratio of hoop-to-axial stress is 2 : 1 in orthotropic pipes ; however, the ratio proved to be not 2 : 1 in anisotropic pipes due to the coupling effect. The stress and deformation of filament-wound pipes strongly depend on the winding angle and the winding sequence.
