The compression properties of an aluminium foam containing a nonuniform density gradient have been examined. Specimens were taken from various locations within the foam slab, and were tested in two directions. Measured foam properties were compared to calculated values using models derived by Ashby and Gibson . The effect of the density gradient on the compression properties and also the energy absorption characteristics of the foam was found to be significant.
