DEVELOPMENT EPOKSYKOMPOZYTNYH INSULATION MATERIALS FOR THE REPAIR ELEMENTS EMS MARITIME TRANSPORT
Abstract
The effect of temperature on the electrical breakdown voltage change epoxy composites material filled with particles of different nature and dispersion. Experimentally that the breakdown voltage, and, respectively, and the dielectric strength epoxy composites essentially depends on the ambient temperature. Top specified characteristics depending established for composite coatings with particles of carbide mixture (50 mas.ch.) and colloidal sulfur (50 mas.ch.). Proved that treatment ferromagnetic fillers pulsed high-frequency magnetic field is not substantially affect the electric strength coatings. Additionally, it is shown that a significant reduction in breakdown voltage of all investigated epoxy composites observed in the temperature range 333 ... 353 K, due to the phenomenon of transition epoxy composites coverage in highly solid state.
