Epoxy/UHMWPE Composite Hybridized with Gadolinium Nanoparticles for Space Exploration

Abstract Deep space radiations pose a major threat to the astronauts and their space craft during the long duration space exploration expeditions [1]. 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.

One of the commercialization strategy that will be adopted would involve licensing the technology that will be developed to produce Epoxy/UHMWPE Composites Hybridized with Gadolinium Nanoparticles. Alternatively, spinoff of AmChemteq Inc. will be established with the sole objective of perfecting the production of Epoxy/UHMWPE Composites Hybridized with Gadolinium Nanoparticles for domestic and international market. State of Pennsylvania will match every dollar invested in the spinoff company to encourage the job creation in the state.

The nanoparticles with high neutron adsorptions are not readily available in the market, therefore the proposed research entitled "Epoxy/UHMWPE Composites Hybridized with Gadolinium Nanoparticles for Application in Space Exploration Vehicles" will not only provide means to produce light weight radiation shielding materials but also offer technique to process nanoparticles with high neutron adsorptions in a cost effective manner. The Epoxy/UHMWPE Composites Hybridized with Gadolinium Nanoparticles will not only be very handy during a nuclear but also used by workers who are routinely exposed to nuclear radiations at their work place.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
