Abstract
Abstract A laminated armor construction formed of a plurality of layers adapted to protect against missiles by a combination of projectile deflection, diffusion of forces, dissipation of energy into heat, modification of force vectors and adsorption of kinetic energy. A first layer of elliptical plastic plates causes deflection with the energy dissipation and adsorption being achieved by underlying layers of foam plastic, and a metal honeycomb filled with epoxy.
