  • In terms of material advances that are needed, Misra said there needed to be: (1) materials with higher electrical conductivity than copper; (2) electrical insulating materials with high thermal conductivity and high breakdown voltage; (3) high-temperature magnets; (5) nanocomposite magnets capable of operating at high frequencies with low loss; (6) additive manufacturing that would enable high-power-density motors and provide design flexibilities; (7) advanced thermal interface materials; (8) battery materials with engineered structures and desired electrochemical properties; and (9) multifunctional materials. “With the growing trend toward development of all solid-state batteries for electric vehicle applications, the battery industry will look for advanced ceramic materials and cost-effective manufacturing techniques for producing all solid-state batteries,” he added. Approaches include polymer-ceramic composites and multilayer insulation incorporating ceramics; (2) demonstration of magnesium diboride conducting coils for application in superconducting motors; and (3) development and demonstration of solid oxide fuel cell technology for aircraft applications,” Misra divulged.Besides research in electrified aircraft, NASA’s John H. Glenn Research Centre has a broad portfolio on ceramics research, which include: (1) increasing temperature capability of ceramic matrix composites for gas turbine engine applications; (2) developing complex oxide environmental and thermal barrier coatings for protecting gas turbine engine hot section components; (3) silicon carbide-based high-temperature sensors for extreme environments; and (4) ceramic thermal barrier seals.
