Improved composite armor designs uses optimally shaped ceramic pellets, a specific stacking geometry and a web system for patterning the pellets, improving manufacturability, and providing additional structural reinforcement. Lightweight, composite ballistic armor according to the invention may comprise an array of ceramic pellets, each pellet having a front surface, a back surface and a longitudinal centerline, and wherein the front surface of each pellet is intentionally convex. The front surface of each pellet may be hemispherical, in which case the cross-section of the pellet taken perpendicular to the centerline may be oval-shaped. Alternatively, the front surface of each pellet may be elliptical, in which case the cross-section of the pellet taken perpendicular to the centerline may be circular. In the preferred embodiment, the back surface of each pellet is formed at the same angle relative to its centerline, with the pellets being arranged with the flat surfaces lying in a plane. The pellets may be arranged in a square matrix, or may be arranged in a hexagonally close-packed matrix. The array of pellets may be embedded in a hardened matrix material, and/or tied together with netting material.

I claim: 1. Lightweight, composite ballistic armor, comprising: an array of ceramic pellets, each pellet having a front surface, a back surface and a longitudinal centerline; and wherein: the front surface of each pellet is intentionally convex, the front and back surfaces of the pellets define parallel, spaced-apart front and back planes, and the longitudinal centerlines of the pellets are parallel to one another and angled relative to the front and back planes at an angle other 90 degrees. 2. The lightweight, composite ballistic armor of claim 1, wherein the front surface of each pellet is hemispherical. 3. The lightweight, composite ballistic armor of claim 1, wherein: the front surface of each pellet is hemispherical; and the cross-section of the pellet taken perpendicular to the centerline is oval-shaped. 4. The lightweight, composite ballistic armor of claim 1, wherein the front surface of each pellet is elliptical. 5. The lightweight, composite ballistic armor of claim 1, wherein: the front surface of each pellet is elliptical; and the cross-section of the pellet taken perpendicular to the centerline is circular. 6. The lightweight, composite ballistic armor of claim 1, wherein: the back surface of each pellet is substantially flat; and the pellets are arranged with the flat surfaces in a flat back plane. 7. The lightweight, composite ballistic armor of claim 1, wherein the pellets are arranged in a square matrix. 8. The lightweight, composite ballistic armor of claim 1, wherein the pellets are arranged in a hexagonally close-packed matrix. 9. The lightweight, composite ballistic armor of claim 1, wherein the array of pellets are embedded in a hardened thermoset or thermoplastic polymer matrix material. 10. The lightweight, composite ballistic armor of claim 1, wherein: the array of pellets are tied together with fibrous netting material; and the tied pellets are embedded in a hardened matrix. 11. The lightweight, composite ballistic armor of claim 1, wherein: the array of pellets are tied together with fibrous netting material; and the tied pellets are embedded in a hardened matrix; and the matrix is strengthened with a nano-clay component. 12. The lightweight, composite ballistic armor of claim 1, wherein the array of pellets are embedded in a hardened matrix material forming a plurality of front plates, and further including: a flexible, web-based support structure; and a plurality of tiles attached to the support structure, each tile including a front plate disposed on one side of the support structure, a back plate disposed on the other side of the support structure, and one or more fasteners for joining each front plate to a corresponding back plate through the support structure. 13. The lightweight, composite ballistic armor of claim 12, wherein each back plate is a composite structure including opposing panels filled with a resin impregnated matrix. 14. The lightweight, composite ballistic armor of claim 12, wherein the back and front plates are co-extensive. 15. The lightweight, composite ballistic armor of claim 12, wherein the web-based support structure can bend along lines between the tiles, resulting in a hinged sheet that can be draped over a vehicle or other thing to be protected. 16. The lightweight, composite ballistic armor of claim 12, wherein the ceramic pellets are bound together with a network of cables embedded in the hardened matrix material.
