Abstract
The invention provides a composite armor plate for absorbing and dissipating kinetic energy from high-velocity projectiles, the plate comprising a single internal layer of pellets which are bound and retained in plate form the pellets being characterized by a substantially regular geometric cross-sectional area, the cross-sectional area being substantially polygonal with rounded corners.
Claims6
A composite armor plate comprising:
- a single internal layer of pellets made of ceramic material disposed in a plurality of spaced-apart rows and columns, which are bound and retained in plate form by an elastic material;
- a majority of said pellets having at least one convexly curved end face;
- an outer impact receiving major surface defined by said convexly curved end faces of said pellets for absorbing and dissipating kinetic energy from high-velocity projectiles;
- said convexly curved end faces of said pellets receiving impact from high-velocity projectiles and absorbing and dissipating kinetic energy therefrom;
- said pellets having a substantially regular polygonal outer surface with the corners of the polygon being eliminated to form rounded corners;
- a majority of each of said pellets being in direct contact with six adjacent pellets in the same layer to provide mutual lateral confinement there between to trap said high-velocity projectiles;
- a valley space being defined between three adjacent pellets, said valley space being substantially smaller than a valley space defined by three cylindrical pellets having a diameter the same as said polygonal pellets with rounded corners;
- and
- a plurality of said pellets defining an opening extending into said pellet from a surface opposite to said outer impact receiving convexly cured end face of said pellet to reduce the weight per area thereof.
