Unidirectional fiber-reinforced filament-wound composite shells of revolution after heat curing treatment often develop high shearing stresses at the interface of laminates, most noticeable near the boundaries where bending moments prevail owing to the support constraints. Effect of altering the thickness ratio of the inner and outer layers and also the fiber orientation in the layers on the interface axial shear stresses in a two-layer shell is studied by a mechanics of materials approach. The results show that slight change in the fiber orientation can reduce the interface axial shear stresses substantial ly.
