SBIR-STTR Award

Advanced Materials Technology, Inc (AMTI) responds to the NASA SBIR solicitation X8 "Space Cryogenic Systems" under subtopic X8.01, "Cryogenic Fluid Transfer and Handling". The proposed Phase I SBIR program is aimed at developing new cryogenic insulations for passive thermal control, resulting in zero boil-off storage of cryogens. The passive thermal control will serve to limit the heat leak into the cryogenic storage system. The proposed technology is expected to increase reliability, increase cryogenic system performance, and is capable of being made flight qualified for the flight systems and to meet Exploration Systems mission requirements. We propose to develop advanced closed cell organic/inorganic hybrid microfoams offering affordable cost, lightweight, high strength, low thermal conductivity, high thermal stability, and easy processability which will result in improved efficiency and reliability of the cryogenic systems. The proposed approach will be environmentally friendly and will not emit any volatile organic compound (VOC). The closed cell structure of these novel foams will prevent the occurrence of cryopumping. Once the feasibility of fabrication of strong, lightweight cryogenic insulating materials by the proposed technology is demonstrated in Phase I, we shall scale-up this technology in a Phase II program to meet the NASA's requirements.

The proposed technology is expected to increase reliability, increase cryogenic system performance, and is capable of being made flight qualified for the flight systems and to meet Exploration Systems mission requirements. We will continue to use the technical approaches that have shown tremendous potential during the successful Phase I effort. Our key approach will be based on the development, fabrication, and characterization of organic-inorganic hybrid nanocomposite microfoams. In the Phase I program, we successfully demonstrated the feasibility of fabrication of these new foams with significantly improved morphology and thermo-mechanical properties. The proposed approach will utilize environmentally friendly blowing agents. The closed cell structure of these novel foams will prevent the occurrence of cryopumping. The proposed effort will further enhance and optimize the novel microfoams, scale up the optimized materials, and culminate in the fabrication of prototype materials to demonstrate the readiness and maturity of our techniques.
