Armor Plate with Shock Wave Absorbing Properties

摘要

A composite armor plate includes a fracture layer placed adjacent to a ceramic layer. The ceramic layer provides a ballistic resistant layer that receives a ballistic impact and propagates a compression wave. The fracture layer is placed behind the ceramic layer and absorbs a portion of the compression wave propagating out in front of the ballistic impact. The absorbed compression wave causes the fracture layer to at least partially disintegrate into fine particles, which dissipates energy in the process. To cause a higher degree of fracturing (and thus larger dissipation of compression wave energy) the fracture layer includes a plurality of resonators embedded in a fracture material.

1. An armor plate comprising:
a ceramic layer having a first side and an opposing second side; and a fracture layer disposed adjacent to the second side of the ceramic layer, the fracture layer being comprised of glass and a plurality of particulate resonators dispersed within the glass, the particulate resonators having a thickness in a range from 5 nm-100 microns, the particulate resonators being comprised of a material having a greater tensile strength than the glass.
