Abstract:

An assembly mating first and second tubular bodies is disclosed. The mating assembly includes at least a sleeve structure forming a part of the first tubular body and defining an inner receptacle surface region, a compression loading assembly integrally formed with, constituted by, or otherwise securable to the second tubular body and at least partially received in the sleeve structure, and a cured adhesive bond positioned between an exterior surface region of the compression loading assembly and the inner receptacle surface region to couple the sleeve structure to the compression loading assembly. The compression loading assembly is laterally expandable at at least the exterior surface region thereof and constructed and arranged relative to the cured adhesive bond so that expansion of the exterior surface region compressively loads the cured adhesive bond in a substantially lateral direction. The strength of the adhesive bond is thereby increased against shear stresses acting on said mating assembly due to longitudinal and/or torsional loading.
