This SBIR involves the development of a lightweight innovative material for use as structure and radiation shielding in one. APS has assembled a uniquely qualified team that includes designers, testing experts and consolidation companies to address this need. Reducing the number of parts on a vehicle is important from a cost, weight and performance aspects. Several systems and radiation sources will be evaluated, and APS will use its TRL 6 materials to meet current NASA and aerospace needs. Phase II will involve further component, characterization and performance issues.
