Abstract
Abstract Protective armor in which the core is an assemblage of tiles, preferably of ceramic material, arranged in edge-to-edge relationship in a checkerboard pattern, and a series of tapes, preferably of fiberglass fabric, interwoven in a zig-zag path longitudinally and transversely over and under the tiles in each row, the assembly being bonded together by a cured synthetic resin impregnated into the tapes. A novel method of interweaving the tapes and tiles is disclosed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
102 words
A protective armor comprising: an assemblage of approximately equal size, flat, relatively small tiles arranged in edge-to-edge relationship in a checkerboard pattern such that the tiles are situated in longitudinal and transverse rows, a series of first fabric tapes interwoven in a zig-zag path through each longitudinal row of tiles so as to pass over alternate tiles in the row and under the other tiles in the row, and a series of second fabric tapes interwoven in like fashion through each transverse row of tiles so as to cover each tile on the side opposite that covered by the first fabric tapes.
Claim 2
Dependent Claim
102 words

Claim 3
Dependent Claim
35 words

Claim 9
Dependent Claim
20 words
A protective armor according to claim 6, wherein resin impregnation takes place after assembly of the tape and tile construction.
Claim 10
Dependent Claim
25 words
A protective armor according to claim 6, wherein said tiles are ceramic, said tapes are of fiberglass, and said resin is of the thermosetting type.
Claim 11
Dependent Claim
26 words
