    Patent number: 5060553
    Abstract: An armor material for use in protecting personnel and instrumentation from ball round, armor piercing bullets and shrapnel, comprises a glass-ceramic bonded to an energy absorptive backing comprising high tensile fibers embedded in a natural or synthetic polymer. The glass-ceramic is subjected to controlled crystallization by heat treatment to promote optimum ballistic properties which are equal to or better than those of alumina despite the lower density and hardness of the glass-ceramic material.
