The analysis of ballistics resistance of a combined metal-ceramic material based on high-strength ceramics in conjunction with the intermetallic on high strength metallic substrate layer – (TiB2+NiTi)+Ti in comparison with the steel plates, the titanium alloy BT1-0 plates and the corundum ceramics plates under impact with the steel spherical striker in velocity range about 2500 m/s was carried out. An experimental researches of protective barriers under the high-speed impact were carried out on the high-speed ballistic experimental facility. A mathematical modeling for the porous elastoplastic medium with taking an account various mechanisms of materials disruptions which was modified for mediums with complicated composition was carried out. There is shown, under the considered impact velocity range at breaking through barriers, in spite of low superficial density, a material (TiB2+NiTi)+Ti shows more force impact on the striker and greater penetration resistance then the steel, the titanium and the ceramics.
