Powder-Filled Epoxy Resin as a Promising Material for Cosmic Radiation Shielding

Space radiation has emerged as a critical factor limiting the duration of space missions, as it poses risks to spacecraft and humans. The impact of cosmic radiation on electronics and materials cannot be ignored, making it even more necessary to reduce radiation exposure. To address this issue, researchers are studying nanomaterial additives, which offer a promising approach to improve the performance of composites used in space structures. Among them, nanomaterial-filled epoxy resins have been shown to be effective in shielding against high-energy cosmic rays. This paper explores the potential of epoxy resin-based composites filled with various powders as effective solutions for cosmic radiation shielding. Through experimental studies, the protective properties of various powder additives, including antimony oxide and sodium tungstate, have been investigated. The results reveal exceptional performance against gamma radiation, making these composites promising candidates for protection against cosmic radiation. Their lightweight, cost-effectiveness, ease of fabrication, and radiation durability make them highly attractive for enhancing the safety and reliability of future space exploration.
