Study of the Performance of Adhesive Bonded Joints

Abstract

The effects of selected experimental and material variables on the performanceof metal/metal adhesive bonded joints, are observed. Three adhesives wereused: FM1000, EC2214 and Metlbond 329 with aluminum and titanium adherends. It was found that the tapered bond-lines did not degrade the properties.The viscoelastic flow was considerably reduced. The adhesives at 72 F, andhigher, were elastic only up to about 5 to 15 percent of the fracture stress.The elastic limits were lower and the viscoelastic flow was higher for shearloading than for tension. Raising the test temperature and lowering thestrain rate produce similar effects. Temperature cycles below the curingtemperature did not influence the room-temperature properties. Poor bondingprocedures and out-of- date adhesives provided the most damaging effects onthe properties.
