Abstract

Recently, epoxy resin materials have shown great advantages in both aerospace and nuclear applications. In order to investigate the aging behaviours of epoxy resin cured products under the irradiation of high-energy particles, we subjected self-prepared epoxy materials to proton and electron irradiation tests under different conditions. Various reductions in permittivity and dielectric loss tangent were observed under all four test conditions. Then, the relationships between the changes in dielectric properties and chemical structures are discussed.
