Benefits of technology

[0004] In accordance with the invention, a ceramic armor plate and an armor system that can be produced in a simple manner are provided. A ceramic armor plate is formed in one piece and comprises a plurality of connected segments which are functionally separated by crack stoppers, wherein the crack stoppers serve to prevent the propagation of cracks from one segment to a neighboring segment. In accordance with the invention, a one-piece armor plate incorporating integrally produced crack stoppers is provided. The manufacturing process is therefore considerable simplified since there is no need to manufacture a plurality of individual tiles which must then be

Problems solved by technology

For example, deformation and a decrease in size can occur when manufacturing ceramic plates.
If individual tiles are joined, then it is cons

Example

[0046] The present invention now will be described more fully hereinafter. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. As used in this specification and the claims, the singular forms “a,”“an,” and “the” include plural referents unless the context clearly dictates otherwise.

[0047] A first exemplary embodiment of an armor plate in accordance with the invention is schematically shown in FIG. 1 and bears the general reference 10 therein. The armor plate 10 is made of, for example, a silicon carbide ceramic.

[0048] To form the armor plate 10 of FIG. 1, a carbon-containing armor plate preform is manufactured. For the purposes of manufacturing the armor plate preform, a cellulose-containing material, for example, is used and a porous preform...

Abstract

A ceramic armor plate is proposed which is formed in one piece and which comprises a plurality of connected segments that are functionally separated by crack stoppers, whereby the crack stoppers serve to prevent the propagation of cracks from one segment to a neighboring segment.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of PCT Application No. PCT / EP2005 / 005172, filed May 12, 2005, and also claims the benefit of German Application No. 10 2004 026 515.1, filed May 19, 2004, both of which are incorporated herein by reference in their entirety and for all purposes.BACKGROUND OF THE INVENTION [0002] The invention relates to a ceramic armor plate. Furthermore, the invention relates to an armor system. The invention also relates to a method of manufacturing a ceramic armor plate. [0003] An armor system is known from, for example, EP 0 810 415 B1 (DE 697 07 560 T2). An armor system may comprise a plurality of ceramic tiles arranged in a tile layer. The purpose of the ceramic tiles is to destroy the core of a striking projectile due to the hardness of the ceramic. SUMMARY OF THE INVENTION [0004] In accordance with the invention, a ceramic armor plate and an armor system that can be produced in a simple manner are provided. A c...
