Patent ID: 8739675

Claim:
An armor panel comprising: a first projectile-deflecting section having an outwardly facing surface, the first projectile-deflecting section comprising: a macroscopically orthotropic material comprising a laminate of parallel layers, the layers arranged at a non-parallel angle to the outwardly facing surface, the macroscopically orthotropic material comprised of alternating layers of unidirectional ultra high molecular weight polyethylene fibers in a thermoplastic urethane resin pressed into a first laminate, the alternating layers of unidirectional fibers of the first laminate alternating by 90° with respect to adjacent layers within the first laminate; a further projectile-deflecting section disposed inwardly of the first projectile-deflecting section and comprising: a further macroscopically orthotropic material comprising a laminate of parallel layers, the layers arranged at a further non-parallel angle to the outer surface that is less than the non-parallel angle of the first projectile-deflecting section, the further macroscopically orthotropic material comprised of alternating layers of unidirectional ultra high molecular weight polyethylene fibers in a thermoplastic urethane resin pressed into a further laminate, the alternating layers of the unidirectional fibers of the further laminate alternating by 90° with respect to adjacent layers within the further laminate; the macroscopically orthotropic material of the first projectile-deflecting section and the further macroscopically orthotropic material of the further projectile-deflecting section comprising a same material; and a ballistic layer attached to the further projectile-deflecting section parallel to the outwardly facing surface.
