“Managing Crack Propagation Mechanisms through the Material Selection Process for Coil Windings in High Temperature and Radiation Resistant Applications”
Jeffrey George Hubrig – Vice President, Operations
“Crack Propagation in thermoset resin dielectric insulation systems remains one of the principal failure mechanisms contributing to life cycle performance instability in magnet assemblies designed and manufactured for high temperature and radiation resistant end-use applications. Understanding the interactive relationship between: 1.) Device design configuration, 2.) Ambient exposures, 3.) Dielectric insulation constituent material chemistries; and 4.) Impregnation Processing is essential to achieving life cycle performance stability of insulation systems in these environments. Recognizing how material chemistry and manufacturing process control determines optimum physical property development and establishes the interlaminar shear effects that result in crack propagation, through the cured dielectric, will promote the development of extended life cycle performance for advanced magnet systems in both high temperature and radiation resistant applications.
