The paper describes the complex problem of increasing the penetration power of impactors from highly porous tungsten-based composites by improving their strength properties doping with hardening components. The samples of impactors based on a porous alloy (tungsten + nickel + iron + cobalt) with a 90% tungsten content doped with tungsten carbide and cobalt WCo8 in various concentrations were developed by liquid-phase sintering method. Dynamic tests and mathematical simulation of the interaction of impactors from the developed alloys are carried out at a velocity of collision with a steel shield is in the range 1100 … 2800 m/s. It is shown that the kinetic impactors from the developed composites have high penetrating power into the steel shield in comparison with the weight and size of monolithic tungsten alloy analog during high velocity collision.

In this paper we present calculating and experimental study of high-speed interaction between explosive content, protected by layered-spaced design, and the cermet impactor in wide speed range. An experimental technique and mathematical model of during the behavior of explosives, protected by layer-spaced design, by with high-speed impact. The process of the interaction between the cermet impactor and element of the protective design is customized and depends on the materials of the interacting bodies, the speed and angle of impact.
