Fatigue properties of EP/A356 aluminium matrix syntactic foams with different densities

The fatigue properties of EP/A356 aluminium matrix syntactic foams were measured. Four different type of syntactic foam were produced in order to determine the relation between the density and the fatigue properties. The density range was set to be between 0.7 1 1.1 g/cm³. The measured values indicated that, both the fatigue limit and the slope of the Wöhler curve increased with the density. However, the comparison of Globocer filled aluminium matrix syntactic foams with EP filled aluminium matrix syntactic foams suggested that this trend only applicable to foams with identical filler materials.
