The study involves the computational modeling of electrostatic discharge initiation in polymer materials utilized in space environment under low-temperature conditions. To address this challenge, experimental data on the radiation-induced electrical conductivity of polyimide and polyethylene terephthalate at reduced temperatures, have been employed. The simulation encompasses the evaluation of electric field intensity within polyimide and polyethylene terephthalate, facilitating inferences regarding the probability of electrostatic discharge events in these materials under both normal and low-temperature scenarios. Additionally, a computational modeling methodology for the electrization of polymer materials is proposed, including the Rose-Fowler-Vaisberg model to account for radiation-induced electrical conductivity.
