Abstract
An armor panel system has a projectile-deflecting section having an outwardly facing surface. The projectile-deflecting section is formed of a material arranged in parallel layers, the layers arranged at a non-parallel angle to the outer surface. The non-parallel angles deflect or rotate an incoming projectile.
Claims6
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.
