Stabilized Aluminum Foam (SAF) is a material produced by introducing gas bubbles into molten aluminum. Two examples will be used to illustrate the potential use of SAF in energy absorption and structural reinforcement applications. The first is use of SAF in a crashbox to absorb energy in a 15km/hr collision and prevent damage to the rails as part of a front-end energy management system. The second is as a filler in a hollow structure subject to bending loads, which potentially could find application in rails and pillars. By filling a hollow structure with SAF, the bending strength is increased dramatically while the weight increases are not significant. Numerical modeling using LS DYNA gave very good agreement with experimental results.
