Abstract: Volumetric samples of pure ultra-high molecular polyethylene and volumetric samples reinforced with metal interlayers (steel grids and perforated titanium plates) are obtained by cyclic shock pressing. Experiments are carried out in which the properties of compacts made of ultra-high molecular polyethylene with and without metal interlayers are studied during perforation by a lead ball (shot) with a diameter of 8 mm flying at a velocity of approximately 370 m/s. The depth of penetration of a fraction into a compact is experimentally determined. To estimate the penetration depth of a spherical body into a polymer, a model is proposed that describes the motion of a ball in this medium.

Keywords: cyclic shock pressing, ultra-high molecular polyethylene, compact, reinforcing layers, punching, viscosity, strength.
