Patent ID: 8069770

Claim:
A modular spaced armor assembly comprising: a ceramic face plate having an exposed upper surface; a composite backing plate having an exposed bottom surface; a lightweight low-density module between the ceramic face plate and the composite backing plate, the lightweight low-density module being directly bonded to and abutting each of the ceramic face plate and the composite backing plate, wherein the lightweight low-density module is a foam material having one or more gas-filled cavities, wherein the gas comprises at least 30% of the volume of the lightweight low-density module; one or more compressible encapsulation plates forming a continuous band surrounding the ceramic face plate the composite backing plate and the lightweight low-density module, exposing only the upper surface of the ceramic face plate and the bottom surface of the composite backing plate, wherein the ratio of the thickness of the ceramic face plate to the thickness of the lightweight low-density module is about 1 to 10 to about 1 to 25, and wherein the ratio of the thickness of the composite backing plate to the thickness of the lightweight low-density module is about 1 to 20 to about 1 to 50.
