Abstract Deep space radiations pose a major threat to the astronauts and their space craft during the long duration space exploration expeditions . Ultra High Molecular Weight Polyethylene (UHMWPE) fibers apart from possessing radiation shielding properties by the virtue of the high hydrogen content are known for extraordinary properties. To prevent the deleterious effects of secondary neutrons, targets such as Gadolinium are required. The objective of the proposed research is to develop Ultra High Molecular Weight Polyethylene (UHMWPE) Fiber Epoxy Composite Hybridized with Nanoparticles of Gadolinium for Radiation Shielding Application. Experience gained in the proposed study could be used to design light weight radiation shielding structures for aerospace application.
