STUDY ON INTERFACE POLARIZATION OF RUBBER-TOUGHENED EPOXY RESINS
-
Abstract
Dielectric properties of 40 percent QR toughening-agent toughened anhydride-cured epoxy resins (EP)and pure anhydride-cured EP were measured. The relationships between the relative permittivity and dielectric loss of cured EP with temperature and frequency were also studied.The interfacial polarization process could be described by the MWS model owing to the phase separation process taking place during the cure.
