Abstract
Bulk samples of GUR 4150 ultra-high-molecular-weight polyethylene with a molar mass of 9.2 х 106 g/mol are obtained by cyclic impact compaction. During compaction, the material remains in a solid state, which ensures the preservation of the crystalline phase with a volume fraction of up to 66%. The strength properties of the samples are not inferior to those of the products obtained using industrial hot pressing. It is shown that the method described here is suitable for obtaining compacts with micro- and nanosized additives.
