Abstract

The study investigated the influence of soft (λ = 0.154 nm) and hard (λ = 0.02 nm) X-ray radiation on the microstructure and mechanical properties of a fluoropolymer composite. The object of research for studying radiation interaction with fluoropolymer composites was the fluoropolymer material with carbon nanofibers “Superfluvis,” developed at the V.A. Bely Institute of Mechanics of Metal-Polymer Systems (Republic of Belarus). This material is widely used in automotive and mechanical engineering for creating structures capable of withstanding extreme loads. It was found that irradiation of the composite fluoropolymer material for 60 min leads to a 25% increase in wear resistance and a 10% increase in microhardness, which is attributed to the dominance of radiation-induced cross-linking processes in macromolecules. Conversely, it was shown that irradiation with hard radiation for 1 h results in material degradation: wear resistance decreases by 84%, and plasticity decreases by 42%.
