Abstract
Abstract An armor system matrix is provided, having a multiple layer system of very hard geometric objects tensionally restrained in their layers by fiber material interwoven about the objects with the objects and fiber material being bonded together by an adhesive material. The objects are substantially spherical ceramic material which may be of different dimensions, each ceramic sphere being substantially in contact with adjacent spheres on the same and adjacent parallel layers. Larger ceramic spheres may be located in the layers closer to the exposed surface of the armor system. The tensional relationship of the ceramic objects in each layer effectively distributes the impact of projectiles over a greater surface area.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
In an armor system matrix, the combination of a plurality of very hard substantially uniformly geometric shaped objects arranged in parallel layered patterns whereby each object is substantially in contact with those adjacent thereon on all sides, said objects being spherically shaped with larger spheres adjacent to the normally outward and exposed surface, a material of great tensile strength interlaced between and around adjacent objects to be in tension while supporting the objects in their aligned relation, and an adhesive means to bond the objects and materials of the matrix into a solid and integral form.
Claim 2
Dependent Claim
96 words
In an armor system matrix, the combination of a plurality of very hard substantially uniformly geometric shaped objects arranged in parallel layered patterns whereby each object is substantially in contact with those adjacent thereon on all sides, said objects being spherically shaped with larger spheres adjacent to the normally outward and exposed surface, a material of great tensile strength interlaced between and around adjacent objects to be in tension while supporting the objects in their aligned relation, and an adhesive means to bond the objects and materials of the matrix into a solid and integral form.
Claim 3
Dependent Claim
111 words
In an armor system matrix the combination of a plurality of very hard spherical shaped ceramic balls of various sizes arranged in oriented layers with balls of uniform size in each layer, and the balls of adjacent layers arranged between each other in overlapped relation whereby all balls are substantially in contact with all adjacent balls in their layers and adjacent layers, a glass fiber and resin material of great tensile strength interlaced between and around adjacent balls in layers to be in tension while supporting the balls in their respective layers, and adhesive means to bond the balls and material of the matrix into a substantially solid and integral form.
Claim 4
Dependent Claim
111 words
In an armor system matrix the combination of a plurality of very hard spherical shaped ceramic balls of various sizes arranged in oriented layers with balls of uniform size in each layer, and the balls of adjacent layers arranged between each other in overlapped relation whereby all balls are substantially in contact with all adjacent balls in their layers and adjacent layers, a glass fiber and resin material of great tensile strength interlaced between and around adjacent balls in layers to be in tension while supporting the balls in their respective layers, and adhesive means to bond the balls and material of the matrix into a substantially solid and integral form.
Claim 5
Dependent Claim
19 words
A matrix according to claim 2 where each ball is in compressive support by at least four other balls.
Claim 6
Dependent Claim
28 words
A matrix according to claim 2 where the normally outward and exposed surface thereof is formed of balls of larger diameter than certain other layers of the matrix.
Claim 7
Dependent Claim
31 words
A matrix according to claim 2 where the objects in each respective layer are uniform in size, but the objects in at least certain of the layers are of varying size.
