An axially extending tubular composite member having a plurality of plies and extending along a longitudinal axis has at least three plies with selectively structured fiber components in each ply. Typically an inner ply has at least one biaxial fiber component, an intermediate ply has at least an axial fiber component that typically is combined with two further fibers to form a triaxial fiber component. Another ply typically has a woven fiber component. A further ply having a biaxial component either replaces the ply of woven fiber or is disposed beneath it over the intermediate ply. A surface veil having fiber and an excess of resin material typically covers at least the innermost or outermost surface of the composite member. An internal web member can be provided, and typically also employs fibers and the matrix material.
