This paper describes methods of joining aluminum foams with mechanical fasteners and with
adhesives, and characterizes the mechanical properties of the resulting joints. Different
techniques of joining were investigated under monotonic and cyclic pull-out and bearing loads. The
effects of fastener geometry on pull-out and bearing-load failure are modelled. Cyclic loading
reduces the maximum load a fastener can carry without failure to 0.35 of the static failure load.
Epoxy adhesive joints are stronger than the foam itself in all modes of loading: failure always
occurs remote from the joint.
