Abstract :
A DGEBA-type epoxy resin filled with silica flour has been submitted to long-term electro-thermal, or purely thermal, aging. Following this aging dielectric spectroscopy and current measurements were made. Changes in low frequency permittivity and loss tangent have been observed. The relative contributions to aging of the electric field and the temperature are discussed.
