Abstract
Abstract Armor element for protection against projectiles, formed by a core made of ceramic material covered with a metal envelope obtained by casting around the core a resilient alloy having high antiballistic efficiency. The envelope is strongly prestressed at casting around the ceramic core in order to inhibit the fragmentation thereof under shock due to the impact of a projectile. The invention can be applied to constructing flexible armor implements by assembling and hingedly interconnecting juxtaposed armor elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
In a method of providing anti-projectile armoring protection to an object, the improvement comprising placing a plurality of armor element tiles side by side to form a layer for protecting the object, without there being a continuous cast matrix between the tiles, each of the tiles comprising a ceramic core and a cast metallic envelope pressing against the ceramic core.
Claim 2
Dependent Claim
60 words
In a method of providing anti-projectile armoring protection to an object, the improvement comprising placing a plurality of armor element tiles side by side to form a layer for protecting the object, without there being a continuous cast matrix between the tiles, each of the tiles comprising a ceramic core and a cast metallic envelope pressing against the ceramic core.
Claim 3
Dependent Claim
13 words
The method of claim 1, wherein the metallic envelope is an aluminum alloy.
Claim 4
Dependent Claim
50 words
The method of claim 1, wherein each of said armor element tiles further comprises integrally formed hinge lugs on its lateral faces, said hinge lugs having through-holes formed therethrough, wherein the hinge lugs of adjacent armor element tiles are interlocked and connected by hinging members through the thus-interlocked hinge lugs.
Claim 5
Dependent Claim
16 words
The method of claim 1, wherein the armor element tiles are affixed to a textile cloth.
Claim 6
Dependent Claim
44 words
The method of claim 1, wherein the thickness of the metallic envelopes at the edges of the tiles is sufficiently small so that the ceramic cores of adjacent tiles are spaced closely enough together to provide protection against projectiles striking areas between adjacent tiles.
Claim 7
Dependent Claim
59 words
In an object having armoring to provide anti-projectile armoring protection, the improvement comprising a plurality of armor element tiles placed side by side to form a layer for protecting the object, without there being a continuous cast matrix between the tiles, each of the tiles comprising a ceramic core and a cast metallic envelope pressing against the ceramic core.
Claim 8
Dependent Claim
59 words
In an object having armoring to provide anti-projectile armoring protection, the improvement comprising a plurality of armor element tiles placed side by side to form a layer for protecting the object, without there being a continuous cast matrix between the tiles, each of the tiles comprising a ceramic core and a cast metallic envelope pressing against the ceramic core.
Claim 9
Dependent Claim
15 words
An object as claimed in claim 6, wherein the metallic envelope is an aluminum alloy.
Claim 10
Dependent Claim
52 words
An object as claimed in claim 6, wherein each of said armor element tiles further comprises integrally formed hinge lugs on its lateral faces, said hinge lugs having through-holes formed therethrough, wherein the hinge lugs of adjacent armor element tiles are interlocked and connected by hinging members through the thus-interlocked hinge lugs.
Claim 11
Dependent Claim
18 words
An object as claimed in claim 6, wherein the armor element tiles are affixed to a textile cloth.
Claim 12
Dependent Claim
44 words
The object of claim 6, wherein the thickness of the metallic envelopes at the edges of the tiles is sufficiently small so that the ceramic cores of adjacent tiles are spaced closely enough together to provide protection against projectiles striking areas between adjacent tiles.
