This research presents the results of comparative analyses of the physical and mechanical properties of ultra-high molecular weight polyethylene (UHMWPE) and modified polymer composite materials (PCMs) following field bench testing. These analyses were conducted at a climatic testing facility in Yakutsk during March and October. The study examined changes in the physical and mechanical properties of the samples after exposure durations of 30, 105, 135, 180, 270, and 365 days. The findings indicate that the aging process of UHMWPE predominantly occurs during the summer months, despite variations associated with seasonal changes. Infrared (IR) spectroscopy was utilized to investigate modifications in the physicochemical structure of the materials. A notable acceleration in the photochemical degradation of UHMWPE was observed in the presence of carbon fibers. Additionally, surface temperature calculations for samples exposed to solar radiation under real-world conditions in Yakutsk were performed using a linear regression model. This model was employed to evaluate the surface temperatures of materials with varying colored coatings. The study elucidates the mechanisms by which environmental variables, including temperature, solar radiation, and seasonal exposure, affect the aging processes of UHMWPE and its composites in Yakutia. The results are expected to have significant implications for addressing challenges related to the mitigation of polymer aging. Consequently, it is recommended to further enhance UHMWPE composite materials intended for outdoor applications in Yakutia, such as linings, by incorporating effective stabilizers to reduce light-induced aging effects.
