Abstract

Several ceramic armor systems are provided herein. One such system is a ceramic armor 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 the ceramic plate. A backing is bonded to the exposed face of the shock-absorbing layer. A second such system is a ceramic armor 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.

Claims (18)

1. A ceramic armour system comprising:

an armour plate including at least one layer of a ceramic component selected from the group comprising an integral ceramic plate and a plurality of interconnected ceramic components; and

at least two support layers having at least one first layer formed from a first ceramic material having a high thermal property adhesively secured to at least one second layer formed from a second ceramic material having a high ballistic property, wherein the material of the at least one first layer has a different resistance to penetration by a projectile than the material of the at least one second layer;

wherein the armour plate is directly secured to the at least two support layers by an adhesive.

2. The ceramic armour system of claim 1 , further including a front spall layer bonded to a front surface of the armour plate.

3. The ceramic armour system of claim 1 , further including a shock absorbing layer bonded to a rear surface of the armour plate.

4. The ceramic armour system of claim 1 , further including a front spall layer bonded to a front surface of the armour plate, and a shock absorbing layer bonded to a rear surface of the armour plate.

5. The ceramic armour system of claim 1 , wherein the armour plate comprises alternating layers of said first ceramic material and said second ceramic material.

6. The ceramic armour system of claim 1 , wherein the high thermal property of the first ceramic material includes a melting temperature of about 3000° C.

7. The ceramic armour system of claim 1 , wherein the high ballistic property of the second ceramic material includes a pressure-resisting property sufficient to at least partially protect against pressure exerted from a threat emitted from a plasma jet weapon.

8. The ceramic armour system of claim 7 , wherein the first ceramic material does not melt or crack after absorbing the remaining temperature and pressure exerted from the threat emitted from the plasma jet weapon after the temperature and pressure exerted from the threat is exerted upon the second ceramic material.

9. The ceramic armour system of claim 1 , wherein the first ceramic material includes a melting-temperature of about 2500° C.

10. The ceramic armour system of claim 1 , wherein the at least one first layer of the at least two support layers is directly secured to the at least one second layer of the at least two support layers by an adhesive.

11. A ceramic armour system comprising:

an armour plate including at least one layer of a ceramic component selected from the group comprising an integral ceramic plate and a plurality of interconnected ceramic components; and

at least two support layers including at least one first layer formed from a first ceramic material having a high thermal property adhesively secured to an interlayer of a polymer-ceramic fibre adhesively secured to at least one second layer formed from a second ceramic material having a high ballistic property, wherein the material of the at least one first layer has a different resistance to penetration by a projectile than the material of the at least one second layer;

wherein the armour plate is directly secured to the at least two support layers by an adhesive.

12. The ceramic armour system of claim 11 , wherein the at least one first layer of the at least two support layers is directly secured to the interlayer by an adhesive and the interlayer is directly secured to the at least one second layer of the at least two support layers by an adhesive.
