Abstract
An armor structure is provided by laminating multiple units consisting of one or more ply of unidirectionally oriented polyolefin film or fibers which are positioned so that the lines of orientation of adjacent units are at angles to each other. The armor structure can either be used alone or in combination with other armor materials. Bonding of the plies is achieved solely through the application of heat and pressure to the composite of positioned plies.
Claims20
A laminated armor structure capable of precluding penetration of bullets and shell fragments which comprises a plurality of bonded units wherein each of said units is so positioned that the directions of orientation of adjacent units are at an angle to each other and wherein the ply of each unit is formed from a member selected from the group consisting of unidirectionally oriented olefin polymer film and unidirectionally oriented olefin polymer filament, wherein the ply of each unit is positioned so that the direction of orientation of adjacent ply is the same and wherein said units are compression-bonded in the absence of adhesives or bonding agents.
