because it combines light weight with heat resistancealthough syntactic foams have been around for many years, this is the first development of a lightweight metal matrix syntactic foam.'

'This new development of very light metal matrix composites can swing the pendulum back in favor of metallic materials,

and high buoyancy offered by the new syntactic foams, the researchers explained. The syntactic foam made by DST

and NYU captures the lightness of foams, but adds substantial strength. The secret of this syntactic foam starts with a matrix made of a magnesium alloy,

which is turned then into foam by adding strong, lightweight silicon carbide hollow spheres developed and manufactured by DST.

The hollow particles also offer impact protection to the syntactic foam because each shell acts like an energy absorber during its fracture.
