Abstract: A lightweight composite armor including an integrally formed matrix block is disclosed. The matrix block includes a generally planar back, a plurality of intersecting ridges extending from the front of the planar back, and fillets provided at the junctures between the planar back and the ridges and at the juncture between the ridges. The matrix block thus forms a pattern of open topped cells. An energy absorbing ceramic body is located in each cell. Individual front plates sized to fit in the open top of each associated cell in mating contact with the ceramic body and provided with upstanding flanges around the periphery thereof are also provided. A weld around the periphery of the front plates between the flanges and associated tops of the ridges is provided. In this manner, impact by a projectile on one of these front plates substantially limits any damage to that one front plate and the underlying ceramic body leaving the remaining armor substantially undamaged.

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.

Abstract: A modular armor includes a matrix of interfitted elements which forms a self-supporting layer. Each element has a first rectangular parallelepiped leaf having a length substantially twice the width. The element further includes a second rectangular parallelepiped leaf having the same width and length as the first leaf and which is suitably attached as by integral formation with the first leaf to form a cruciform. The elements in the matrix are suitably held together to form the modular armor. In one embodiment, the leaves of one element are provided with pockets in which ceramic blocks are located. Additional leaves can also be provided with each element to further strengthen the element and to hold the matrix together. Each of the elements can be joined to one another to hold the elements together, or a frame could be provided for the elements.
