Abstract

A shock wave attenuating material () includes a substrate layer (). A plurality () of shock attenuating layers is disposed on the substrate layer (). Each of the plurality () of shock attenuating layers includes a gradient nanoparticle layer () including a plurality of nanoparticles () of different diameters that are arranged in a gradient from smallest diameter to largest diameter and a graphitic layer () disposed adjacent to the gradient nanoparticle layer. The graphitic layer () includes a plurality of carbon allotrope members () suspended in a matrix ().
