| Abstract: | An electron beam(EB)cured epoxy resin system for filament winding of composites was studied in this paper.The change of viscosity with the temperature,and the relations between the glass transition temperature and the radiation doses,and the mechanical properties of the resin system were investigated.The results showed,the viscosity of the resin was 389 mPa·s at 60 ℃,and the optimal EB radiation dose was 150 kGy,and the glass transition temperature of EB-1 resin or EB-4 resin were 212.96 ℃ and 214.77 ℃ respectively.Tensile strength of EB-4 was 52.7 MPa,tensile modulus was 2.79 GPa,and the elongation at break was 2.18%.The EB-4 epoxy resin system was suitable for fabricating advanced composites by filament winding process cured by EB. |
