The paper deals with the issues of increasing the depth and diameter of the cavity in various obstacles under the action of shaped charges covered with copper and tungsten as bimetallic, two-layer combined linings. Barriers made of soft iron and steel of different hardness and strength, as well as combined steel - duralumin and water - steel barriers, simulating various conditions for the penetrating action of shaped charges, are used as breakable barriers. The work is experimental in nature. The results of experimental studies are presented in the form of graphical dependencies, diagrams and X-ray patterns of the formation of a cumulative jet from combined linings. The study comparatively evaluates the action of shaped charges with shaped-charge linings of various designs, including the original single-layer copper lining. The evaluation depends on the method of forming a tungsten layer on the inner surface of the lining and its thickness. The study gives recommendations on the use of shaped charges with combined copper-tungsten shaped linings when acting against various obstacles.
