Abstract
The paper presents the results of experimental investigations on the formation and penetration efficiency of EFP charges with liners performed by applying a powder metallurgy method. Two types of sintered powder liners were tested: liners of the shape of a spherical surface sector and the conical liners with an open apex angle. Liners were made of copper powder and have a base diameter of 45â¯mm and a mass of 30 g. Explosive charges with sintered copper liners were examined using X-ray pulse technique and a high-speed digital camera. Dynamic shaping of explosively formed projectiles was recorded and the perforation of a steel barrier was tested. Concluding, liners for EFP charges made using powder metallurgy technology proved to be a fully featured substitute for conventional spherical liners produced with a technologically more complicated manufacturing process.
