-1- Abstract: The invention provides a composite laminate joint structure for joining articles, e.g. pipes, made of multiple ply composite laminates, and a method for forming such a joint structure. The joint structure comprises a first ply of strands disposed perpendicularly to the axis of the structure, this ply having an exterior surface at one end tapered at an angle of between 5° to 15° when viewed in cross-section relative to the axis. A second ply of strands disposed transversely of the first ply overlies the first ply and extends generally axially. The second ply has a taper where it overlies the end of the first ply. A third ply of strands is disposed transversely of the second ply and overlies the second ply to extend perpendicularly to the axis. The third ply has a flange on the tapered end of the second ply. A hardened adhesive impregnates and bonds all three plies together in a common bonding matrix to maintain the flanged and tapered end configuration.
