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).
Claims20
A composition comprising:
- a plurality of layers, each one of the plurality of layers including:
- (i) a gradient nanoparticle layer comprising a plurality of nanoparticles of at least two different diameters that are arranged in a gradient based on nanoparticle diameter;
- and
- (ii) a carbon allotrope layer disposed adjacent to the gradient nanoparticle layer, the carbon allotrope layer comprising carbon allotrope members suspended in a matrix;
- wherein the carbon allotrope layer of at least one of the plurality of layers is a non-transparent carbon allotrope layer.
