Polyester (polyethylene terephthalate, PET) and high-modulus polyethylene (HMPE) fibers are currently among the most commonly used materials in the manufacturing of ropes for offshore operations. Several studies have been conducted in analytical, experimental, and numerical domains, addressing various factors such as tensile tests, fatigue, creep, and environmental exposure conditions that influence their mechanical behavior. This work presents data from an experimental study on rupture resistance in semi-finished products (rope yarns) of PET and HMPE fibers subjected to different ultraviolet (UV) radiation exposure durations. The experimental procedure involved UV exposure for up to 84 days, followed by tensile rupture tests based on ISO 2062. The results showed that UV degradation occurs in a monotonic manner for PET, whereas HMPE exhibits relative stability for rope yarns.
