ABSTRACT:
An armor component for protecting a body from a high speed projectile, such as a bullet from a handgun or a rifle, and which is designed for flattening and trapping the bullet. The armor may include in combination with the component, which serves as an outer component, an inner component used in a garment or similar article, for spreading the impact of the bullet striking the outer component. The outer component may include a pair of layers of flexible material at least the inner layer of which is high impact-resistant material, and has at least two juxtaposed layers of hard hemispherical beads (or half-spheres) between the flexible layers. The beads in the adjacent layers are disposed with beads thereof inter-nested in the inter-bead spaces of each other. The volume occupied by the layers of beads is preferably substantially void of all other material. The beads of each layer may be arranged in a regular close-packed lattice pattern, i.e., a hexagonal or square so that each bead contacts its immediately adjacent neighbor beads. In either case the flat surface of the outer matrix of half-sphere beads would face outward while the flat surfaces of the inner matrix of half-sphere beads would face inward. A garment using an outer part of this type is light and flexible but is capable of trapping the bullet with little risk of spalling of the parts of the component.
