Patent attributes
A composite structural component made of a polymer matrix composite material includes an end connection that includes an end portion at one end of the composite structural component, comprising an internal surface comprising a plurality of ridges and grooves defining a first engagement surface along an axial direction and a metal interface component comprising an outer surface comprising a plurality of ridges and grooves defining a second engagement surface along the axial direction and an inner surface defining a mounting surface for attachment of an end fitting. The metal interface component is engaged with the internal surface of the composite structural component by mating of the first and second engagement surfaces. The structure also includes an outer annular component fitted around the end portion in axial alignment with the mating of the first and second engagement surfaces.
