University Consortium for Applied Hypersonics Seminar Series: Advancements in High Temperature Radome and Window Materials

Abstract: An overview of the advancements in research and development efforts at The University of Arizona on high-temperature, RF and IR, materials for application as radome and window material systems for hypersonic (platforms) will be discussed. Evaluation of high-temperature mechanical, electrical and toughness behavior of a recently developed class of RF materials shows potential for use in extreme environments. The talk will also address the nature of the material maturation processes that involves both technology readiness level (TRL) and manufacturing readiness level (MRL). The University of Arizona unique facilities for manufacturing high temperature ceramics prototype parts will be highlighted to show the dual nature of MRL and TRL as a case study in the development of high temperature RF prototype parts. The adopted manufacturing approach is based on, Direct Current Sintering Technology which shows potential to be a disruptive manufacturing capability that can increase volume and rate production of window and antennas for hypersonics. This powder-based technology that applies joule heating simultaneously with pressure control has been successfully employed to create large scale window material and complex shape antenna and nose tip materials for operation at high temperatures.
