Abstract
A transparent armor structure is provided by laminating multiple units consisting of one or more ply of unidirectionally oriented olefin polymer film formed by a fluid compression process. The units are positioned so that the lines of orientation of adjacent units are at angles to each other. Bonding of the plies is achieved solely through the application of heat and pressure to the composite of positioned plies.
Claims5
A transparent laminated armor structure capable of precluding penetration of bullets and shell fragments which comprises a plurality of compression-bonded units of unidirectionally, fluid compression oriented olefin polymer film 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 said units are compression-bonded in the absence of achesives or bonding agents.
