Bulk samples of pure ultra-high molecular weight polyethylene and bulk samples reinforced with metal interlayers (steel meshes and penetrated titanium plates) are obtained by cyclic impact compaction. Experiments are carried out in which the properties of compacts made of ultrahigh molecular weight polyethylene with and without metal interlayers are studied during penetration by a lead shot whose pellets (8 mm in diameter) move at a velocity of approximately 370 m/s. The penetration depth of a pellet 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 sphere in this medium.

增强型超高分子量聚乙烯弹道渗透特性

通过循环冲击压实获得纯超高分子量聚乙烯的块状样品和金属夹层（钢网和渗透钛板）增强的块状样品。进行了实验，其中研究了由具有和不具有金属夹层的超高分子量聚乙烯制成的压块在通过铅丸穿透期间的特性，铅丸的颗粒（直径为 8 毫米）以大约 370 米/秒的速度移动。颗粒进入压块的渗透深度是通过实验确定的。为了估计球体进入聚合物的穿透深度，提出了一个模型来描述球体在该介质中的运动。
