A composite marine riser (22) may be formed, in one embodiment, of a pair of threaded metallic sections (115,118) having threaded external surfaces (138,140). The threaded external surfaces may taper from a larger to a smaller diameter. The composite material (120) may be formed over the threaded external surfaces, which surfaces serve to transfer force from the metallic sections to the composite material.
