The article suggests analytical formulas for calculation of penetration speed limit value for a double-layer ceramic-metal protective barrier. Structural and mechanical characteristics of barrier and penetrator materials are taken into consideration. The paper provides the study of such barriers ballistic resistance using the formulas obtained and demonstrates the possibility of such barriers structure optimization. The results of the study correspond to experimental data. The optimum thickness of ceramic layers for barriers with surface densities values within range 30...50 kg/m2 are identified. The article shows that obtained values of thickness have little dependence of barrier surface densities. This values primarily depend on barrier base materials densities
