BALLISTIC EVALUATIONS OF COMPOSITE ARMOR

Abstract

Ballistic evaluations of beryllium, berylliumDoron, alumina-Doron and alumina-beryllium-Doron were conducted with caliber 0.22 -inch and/or caliber 0.30-inch missiles at normal incidence. The areal densities of the targets extended from 1.5 to 10 lbs/sq. ft. The beryllium-Doron composites exhibited excellent fragment armor characteristics while the alumina-Doron composites provided outstanding protection against a single hit type impact by an AP-M2 projectile. The the three phase composite exhibits an improved ballistic limit over either of the two-phase composites at the same areal density against caliber 0.30-in. projectiles. Variations in target composition, structure and support had little if any effect upon the ballistic limit velocities determined on the alumina-Doron composites except that a minimum thickness of about 0.25 in. of alumina is required to cause sufficient core blunting and breakup of the AP-M2 projectile to result in a good armor.
