Enhanced light weight armor system with reactive properties
First Claim
1. An apparatus for protecting against an explosive warhead, comprising:
- an arrangement of multiple structural layers that includes a thin metal sheet imprinted on a first side with a network of adjoining hollow pockets, said sheet coated with a layer of metallic nanopowder and said pockets filled with water and anti-freeze and sealed;
a coat of potassium bicarbonate powder on a second side opposite the first side of the thin metal sheet; and
a composite foam material used to form a matrix with multiple overlapping layers of said thin metal sheet imbedded so that the second side faces toward the surface of a building or vehicle and the first side faces away from the surface of a building or vehicle and arranged so that said layers of metal sheets overlap at an angle relative to the surface of the building or vehicle, said formed matrix referred to as a first foam block.

Abstract
A light-weight armor system for retrofitting onto light vehicles, such as HMMWVs, trucks, or helicopters, or incorporating into a vehicle to protect against HEAT or high explosive warheads. The armor system comprises multiple layers of a thin metal film. The front side of the thin metal sheet facing away from the vehicle is coated with a layer of zirconium nanoparticles and imprinted with a network of hollow packets filled with water and sealed. The back side of the thin metal sheet is coated with a layer of potassium bicarbonate powder. The multiple layers of metal film are imbedded in a matrix of composite foam to form a honeycomb structure that can be retrofitted onto light vehicles or used in new designs.
