Electron beam curing of various blends of epoxy resin was studied in this paper. Radiation effect of epoxy resin systems of 828, 648 and 207, and their blends was compared. The effect of resin compounding ratio and radiation dose on blends of epoxy resin 828 and 648 systems was analyzed. The performance of the blend with different ratio of epoxy resin 207 and 648 was also studied. The results of study show that radiation effect of epoxy resin is associated with its chemical constitution, steric effect, and crystallinity. The mixing of various epoxy resin can improve radiation curing effect of system, reduce required radiation dose, and enhance performance of radiation product.
