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.
