Environmental Effects on the Elastic-Plastic Properties of Adhesives in Bonded Metal Joints (Klimaeinfluss auf die Kennwerte des Elasto-Plastischen Verhaltens von Klebstoffen in Metallklebungen),
Abstract
The shear modulus, the stress at 1% shear strain, the shear strength, the strain at fracture and the appertaining shear stress-strain diagrams are analyses for ten aircraft structural adhesives. These values are calculated from the measured load-deflection behaviour of the adhesives in the bond line of lap joints with a thick adherend and a small overlap length, as well as from the torsion pendulum testing of cast adhesives. The measurements are made before and after a long exposure to warmth, cold, moisture, warmth combined with moisture, and changes between cold and combined warmth and moisture. The environmental effects on the adhesion between adherend and adhesives as observed in the tests are described. (Author-PL).
