An armour material for use in protecting personnel and instrumentation from ball round, armour piercing bullets and shrapnel, comprises a glass-ceramic bonded to an energy absorptive backing comprising high tensile fibres embedded in a natural or synthetic polymer. The glass-ceramic is subjected to controlled crystallisation 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. |
