Abstract
A new, lightweight armor plating for important installations or control cers is disclosed whereupon being struck by a projectile restricts the ensuing shock wave to a narrow beam-like path always perpendicular to patterns of striation engrained in said armor. This response dissipates the projectile's kinetic energy more rapidly. The new armor is lighter than traditional forms of armor.
Claims4
Lightweight armor plating for protecting vital installations or control centers which comprises:
- travertine material of a predetermined thickness that causes an incident projectile to form shear lines that are perpendicular to the pattern of striations engrained in said material, said shear lines being restricted to relatively narrow, parallel lines and not expanding out into a conical form as the force from the projectile travels deeper into said armor, thereby dissipating the projectile's kinetic energy.
In a method for protecting certain vital parts on a ship such as a ship's magazine or control center comprising:
- providing a protective material;
- and
- covering said vital parts with sheets of said material, the improvement residing in utilizing travertine as said protective material.
