Electromagnetic Nondestructive Evaluation of Wire Insulation and Models of Insulation Material Properties

摘要: Polymers have been widely used as wiring electrical insulation materials in space/air-craft. The dielectric properties of polymers can change over time, however, due to various aging processes such exposure heat, humidity and mechanical stress. Therefore, the study is important aerospace industry potential loss life aircraft event an fire caused by breakdown insulation. Part this research focused on studying mechanisms environmental process ways which their material subject processes. other part project determine feasibility a new capacitive nondestructive testing method indicate degradation insulation, measuring its permittivity.
