Abstract
High-density polyethylene (HDPE) is widely used in industrial applications due to its versatility and chemical resistance. Lately, its versatility has been further expanded by surface cross-linking and modification. Also, reduction in the weight of polyethylene is one of the most important requirements in the industry. Creep test is a common method for studying the behavior of materials over a long period of time to design their industrial
applications. Since a conventional creep test requires more than a test time of 10,000 h, a relatively short-time creep behavior can be predicted using time-temperature superposition (TTS) or mathematical modeling. The long-term creep behavior can be predicted by mathematical modeling using the short-term creep data. In this study, the creep behavior of HDPE fibers was measured in the load range of 20–50% of the ultimate tensile strength
(UTS), and compared in terms of the number of filaments and denier. The long-term creep behavior was successfully predicted using the short-term creep behavior data obtained by mathematical modeling. Therefore, this approach can be used to predict the number and denier of PE fibers in industrial applications.
