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 fron t 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 pluralit y of interconnected ceramic components providing an integral plate. The ceramic plate has a deflecting front surface of a flat front surface, and a rear surface. A front spell 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. Th e assembly'of the front spell layer, the ceramic plate, and the shock absorbing layer is bolted to t he hull of a vehicle, preferably with an air gap, or alternatively without an air gap.
Claims (7)
1. An armour 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, the first and second layers of polymer being in the range of 0.007 to 0.030 inches.
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, the first and second layers of polymer being in the range of 0.007 to 0.030 inches.
2. The armour plate of claim 1 wherein the polymer is adhesively fixed through a polyurethane film adhesive.
3. The armour plate of claim 2 wherein the polyurethane film adhesive has a thickness of between 0.015 inches and 0.025 inches.
4. The armour plate of any of claims 1 to 3 wherein the first and second thin layer of high shear strength polymer are comprised of polycarbonate.
5. The armour plate of any of claims 1 to 4 wherein the second thin layer is adapted to follow a contour of said outer surface of said central layer.
6. The armour system of any of claims 1 to 5 wherein said central layer includes nodes on the outer surface of said central layer.
7. The armour plate of claim 6 wherein the second thin layer is adapted to follow contours of the nodes and to fit between the nodes of said central layer.
