Lightweight radiation shielding materials with carbon nanotube reinforcements

Human tissue and electronic component protection from harmful effects of space radiation is essential for extended deep space exploration voyages. The prime objective of this Phase II proposal is to develop a multi-functional composite material design to fulfill the current need for non-parasitic, lightweight, high-strength, and effective radiation shielding materials for space exploration applications. Using their patented rapid prototyping approach, ACR and its partners will fabricate test panels of polymer materials reinforced with aligned functionalized single-walled nanotubes (SWNT). The physical, material, and comprehensive radiation properties of the composites materials will be evaluated to identify optimal radiation shielding design criteria. ACR believes the goals of this Phase II effort are directly in line with the NASA Mission.
