A transition fitting (16) for a high strength composite article (10) comprised of a matrixed skin (12) supported by and bonded to a core (14) to locate the same in an intended structural disposition subjecting the composite and fitting at or about a juncture thereof to bending and/or shear loads, co

A transition fitting (16) for a high strength composite article (10) comprised of a matrixed skin (12) supported by and bonded to a core (14) to locate the same in an intended structural disposition subjecting the composite and fitting at or about a juncture thereof to bending and/or shear loads, comprising a profiled web (22) disposed within the composite article and a shank for fixturing the article, wherein the web includes a longitudinal aspect projecting into the core from the juncture to a tip of the web (26), a lateral aspect projecting across the core bounding the juncture, and a transverse aspect extending through the core; wherein the transverse aspect of the web tapers inwardly along the longitudinal direction of the web toward the tip and is dimensioned to provide load distribution to transfer structural loads from the composite to the fitting along a longitudinal force gradient having a minimum force value at the tip and a maximum force value at the shank, and yet further wherein the lateral aspect is dimensioned to yield a web surface area selected to provide force balancing for maintaining loads transferred to the web along the gradient below the interfacial shear limits at the junctures of the fitting, the core and the skin.

A transition fitting for a high strength composite article, comprised of a matrixed tailored skin support by and bonded to a core, to locate the same in an intended structural disposition subjecting the composite and fitting at or about a juncture thereof to bending and/or shear loads, said fitting

A transition fitting for a high strength composite article, comprised of a matrixed tailored skin support by and bonded to a core, to locate the same in an intended structural disposition subjecting the composite and fitting at or about a juncture thereof to bending and/or shear loads, said fitting comprising a profiled web disposed within said composite article and a shank for fixturing said article, said web including a longitudinal aspect projecting into said core from said juncture to a tip of said web, a lateral aspect projecting across said core bounding said juncture and a transverse aspect extending through said core; wherein said transverse aspect of said web tapers inwardly along the longitudinal direction of said web toward said tip and is dimensioned to provide load distribution means for transferring structural loads from said composite to said fitting along a longitudinal force gradient having a minimum force value at said tip and a maximum force value at said shank, and further wherein said lateral aspect is dimensioned to yield a web surface area selected to provide force balancing means for maintaining loads transferred to said web along said gradient below the interfacial shear limits at the juncture of said fitting, said core and said skin.
