Innovative Nanoparticle Insulation Systems for Fusion Magnets

78759S Fusion magnets require insulation materials that possess high shear strength, excellent electrical insulation characteristics, and radiation resistance. Improvements in insulation technology can contribute to improved magnet performance, and will enable scientists and engineers to overcome current magnet design limitations. To improve the shear strength of composite insulation materials, this project will incorporate nanoscale reinforcements into radiation-resistant organic resins, then fabricate and test composites using these nano-reinforced polymers. The mechanical, electrical, and thermal properties of the various combinations of materials will be characterized for use in fusion applications. Phase I will improve the properties of polymer-matrix composite insulation materials by incorporating nano-reinforcements into the polymer matrix. Phase II will include additional process development, measurement of the radiation-resistance, and the scale-up of these processes for use in fusion magnet applications. Commercial Applications and Other Benefits as described by the awardee: The technology should not only increase the shear strength of the composite insulation system, but also improve radiation resistance and other material properties. In addition to supporting DOE fusion magnet programs, the technology also should have application in: (1) MRI instruments, electric motors, transformers, and conventional magnets; (2) nano-reinforced resins and adhesives with increased strength and thermal conductivity; (3) novel materials with improved strength and toughness for structural applications; and (4) strong, lightweight components for improved fuel efficiency in automobiles and aircraft.
