Abstract
A shock wave attenuating material (100) includes a substrate layer (104). A plurality (110) of shock attenuating layers is disposed on the substrate layer (104). Each of the plurality (110) of shock attenuating layers includes a gradient nanoparticle layer (114) including a plurality of nanoparticles (120) of different diameters that are arranged in a gradient from smallest diameter to largest diameter and a graphitic layer (118) disposed adjacent to the gradient nanoparticle layer. The graphitic layer (118) includes a plurality of carbon allotrope members (128) suspended in a matrix (124).
