Ceramic components, ceramic component systems, and ceramic armour systems
First Claim
1. An amour plate for use in personal vehicular and structural armour systems, comprising:
- i) a central layer of ceramic material of a thickness selected to impart a high impact strength thereto, said central layer having an inner surface and an outer surface;
ii) a first thin layer of high shear strength polymer adhesively affixed to the inner surface of said central layer;
iii) a second thin layer of high shear strength polymer adhesively affixed to the outer surface of said central layer;
wherein said first and second layers of polymer are thick enough to increase the flexural strength of said central layer, and localize shattering of said central layer after the impact of high speed projectiles on said plate.

Abstract
Several ceramic armour systems are provided herein. One such system is a ceramic armour system for personnel. Such system includes an integral ceramic plate, or a plurality of interconnected ceramic components providing an integral plate. The ceramic has a deflecting front surface or a flat front surface, and a rear surface. A front spall layer is bonded to the front surface of the ceramic plate. A shock-absorbing layer is bonded to the rear surface of ceramic plate. A backing is bonded to the exposed face of the shock-absorbing layer. A second such system is a ceramic armour system for vehicles. Such system also includes an integral ceramic plate, or a plurality of interconnected ceramic components providing an integral plate. The ceramic plate has a deflecting front surface or a flat front surface, and a rear surface. A front spall layer is bonded to the front surface of the ceramic plate. A shock-absorbing layer is bonded to the rear surface of the ceramic plate. The assembly of the front spall layer, the ceramic plate, and the shock-absorbing layer is bolted to the hull of a vehicle, preferably with an air gap, or alternatively without an air gap.
