N2 - Metal matrix syntactic foams are composites that incorporate hollow particles in a matrix, where enclosing porosity inside the thin shell of the particle leads to low density without large decreases in mechanical properties. Studies on Al, Mg, Pb, and Zn alloy matrix syntactic foams are available in the published literature. A large stress plateau region appears in the compressive stress-strain graphs of metal matrix syntactic foams. The height and length of stress plateau can be tailored by means of particle wall thickness, volume fraction, and size, and the total compressive energy absorption can be controlled. Metal matrix syntactic foams seem promising in various energy absorbing applications including automobile parts since their energy absorption capability per unit weight is better than other foams and lightweight materials.
