 Abstract

Light alloy specimens consisting of a 2 mm 2024-T load sheet reinforced with doubler plates of 1 mm were loaded in fluctuating tension. Redux and Metlbond 4021 were used as adhesives with glueline thicknesses of about O.05 and 0,5 mm. The Metlbond bonded specimens had a higher endurance than the Redux bonded specimens indicating that in applications like doublers a low rigidity of the adhesive is favourable. The Reduz bonded specimens with a thiok glueline showed porosity and failed by loosening of the doublers. Thick Redux gluelines with gasbubbles have to be avoided.
