  • Publication number: 20140224107
    Abstract: A transparent armor laminate apparatus includes a hard disrupter layer having a substantially planar surface of transparent material configured to erode a ballistic projectile responsive to impact from the projectile, and an absorber configured proximate to the disrupter layer. The absorber includes a first absorber layer and a second absorber layer. The first and second absorber layers may be disposed proximate to each other to define an interface. The first absorber layer may include molecules substantially aligned in a mixture to form a first polymer chain orientation having a first angle relative to the interface and the second absorber layer may include molecules substantially aligned in a mixture to form a second polymer chain orientation having a second angle relative to the interface. A discontinuity exists between the first angle and the second angle or between the first polymer chain orientation and the second polymer chain orientation at the interface.
