NYU School of Engineering creates first-of-its-kind aluminium based metal matrix

The porosity of this lightweight layered material is integrated into metal matrix syntactic foams in their foam-like structure through use of hollow particle.The reserach team used an aluminum alloy packed with hollow alumina particles, which was placed between carbon fabric face-sheets. The layered material they created is lighter in weight, as well as stiffer, with high energy absorption.
This material will likely find application in trains, ships, automobiles and other applications where lightweight structural parts, capable of retaining their strength even after being compressed or bent, are in high demand.
