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.

质子和电子辐照对环氧/酸酐固化物介电性能的影响

近来，环氧树脂材料在航空航天和核能应用中都显示出巨大的优势。为了研究环氧树脂固化物在高能粒子辐照下的老化行为，我们对自制环氧树脂材料进行了不同条件下的质子和电子辐照测试。在所有四种测试条件下都观察到介电常数和介电损耗角正切的各种降低。然后，讨论了介电性能变化与化学结构之间的关系。
