PROTECTIVE CAPABILITY OF NEW TYPE MODIFIED Al2O3 CERAMIC PLATES

Abstract: Below we would like to present the results of applied technological process of obtaining small-sized and large-sized high-strength Al2O3 special ceramic plates. The ceramic plates, produced this way, were fired with B-32 type 14.5 mm amour-piercing bullets. Besides, the Al2O3 ceramics together with other light materials were used in models of composite armour, which was placed in a frame and without a frame during firing. Furthermore, in the RHA witness plate the bulge, indenta-tion and prominence, formed from cracked parts of bullet and ceramics, were measured. The surface mass of composite armours ’ models, tested as well in a frame as without a frame, was determined
