Abstract
Light weight armor comprising lamina-like structures arranged with zones of decreasing Young's modulus and increasing elongation characteristics. The structure contains at least one composite having fibers arranged to dissipate impact forces laterally.
Claims25
An armor structure comprising a plurality of zones of resinous materials, said zones being arranged in decreasing Young's modulus and increasing elongation characteristics, at least one of said zones comprising a resin matrix having fibers incorporated therein;
- said resin matrix having the same or higher elongation at break as the fibers incorporated therein, and said fibers being oriented to transfer impact energy laterally.
The armor sturcture of claim 17 wherein at least one zone contains fibers arranged in a manner and direction to transfer impact forces laterally.
The armor structure of claim 25 wherein said fibers are selectd from the group consisting aramid, carbon, linear crystallized polyolefins and glass fibers.
An armor structure comprising a thermoplastic interpenetrating polymer network composition having a plurality of polymer zones arranged in decreasing Young's modulus and increasing elongation characteristics, at least one of said zones having fibers incorporated therein, said fibers being oriented to transfer impact energy laterally, said fibers having the same or higher elongation at break as the polymer in which said fibers are incorporated.
An armor structure comprising a plurality of lamina sturctures of resinous materials arranged in order of decreasing Young's modulus and increasing in break characteristics at least one of said lamina having fibers incorporated therein which are oriented to transfer impact energy laterally, said resinous materials having substantially the same or higher elongation at break as the fibers incorporated therein.
