Effective space radiation shielding is extremely crucial to the well-being of astronauts, to prevent them from serious health implications, such as immunity dysfunction, carcinogenesis, skin injuries, and more [1]. Spacecraft components are currently manufactured from aluminum owing to their cost-effectiveness and low weight. However, Aluminum performs poorly in providing effective spacecraft shielding against radiation [2]. Long and pure fibers of CNTs cannot be produced by typically used Chemical Vapor Deposition due to the limited amount of supply of catalyst that can be provided [3]. CNTs are polymerized with different materials such as epoxy resin to obtain long fibers. But in this process some properties like thermal radiation shielding capacity are compromised, which becomes a major concern for aerospace engineers [4]. Implementing the novel technology that Tuball has developed using the CNTs and using NH2 - MWCNT/HRB nanocomposite as a radiation-shielding material in spacecraft, may prove more effective than present materials in missions with long-term exposure to thermal radiation. Its characteristic of being a low atomic number polymer will offer significant mass savings without compromising on any other mechanical properties like tensile strength. Keywords: NH2- MWCNT/HRB nanocomposite, Radiation shielding, Thermal expansion, Tensile strength, Carbon nanotubes (CNTs).
