Resistance Spot Weld-Adhesive Bonding Process.

Abstract

A manufacturing technology for the spot weld-dhesive bonding process, describedas weldbonding, was developed. A fuselage barrel section, 85 inches in diameterby 120 inches in length, was designed and built to simulate structures common tothe Lockheed C- , C-130, and C-140 aircraft. The barrel section was joinedthroughout utilizing a weldbonding process whereby adherends were joined one tothe other and in combinations to the fuselage skin by resistance spot weldingthrough thermo-curing, high strength past epoxy adhesive. Barrel section wastested under both static and fatigue limit loads to establish equivalency orsuperiority of the process as compared to other joining processes. The fuselagewas tested statically under up bending, down bending, side bending, and torsionlimit loads. Superiority of static and fatigue strength of weldbond joints, ofthe fuselage barrel section, offers a definite design advantage as compared toconventional mechanical joints. (Author, modified-PL)
