| Abstract: | By using the prepolymer of o,o' diallyl bisphenol A modified bis(4.4' maleimide phenyl) metheat to modify the anhydride/epoxy resin curable system, a heat resistant resin matrix formulation was optimized. Curing mechanism and kinetic of the modified epoxy resin system were studied by DSC, TGA and FT IR. The all round properties of the cured compound epoxy resin system and the glass fiber reinforced epoxy resin matrix pultrusion rod were also studied. Experiments show that the resin matrix was suited for pultrusion. And the properties of the insulant rod have reached the requirements of the technical standards. |
