70312 In many next-step fusion magnet designs, the shear strength of the insulation and its adhesion to the conductor are limiting factors. These designs require significant changes (such as applying large compressive loads or increasing part cross-sections) to accommodate the low shear strength, especially at elevated temperatures. An improved shear strength for the insulation/conductor system would reduce these constraints and allow for higher temperature operation. This project will utilize the enhanced properties of new cyanate-ester-based chemistry to develop insulation with increased shear strength and elevated temperature operation. Phase I will investigate new chemistries of additives, tougheners, and primers as well as improved methods to prepare the conductor and insulation during manufacturing. The economics of both the materials and processes will be addressed. Shear strength testing will be performed at cryogenic and elevated temperatures. Commercial Applications and Other Benefits as described by the awardee: Many different components within fusion devices and experiments could benefit from radiation resistant electrical insulation/conductor systems with improved shear strength. Electrical feed-throughs, ground planes, support structures and the like could be more efficiently designed or exhibit enhanced performance or lower leak rates if they can be more strongly bonded to their surroundings.
