Abstract: The curing reactions of hydrogenated bisphenol A type epoxy resin with three different kinds of curing agents, such as polyether amine (D-230, T-403) and methyl tetrahydrophthalic anhydride (MeTHPA) were researched in this paper. The curing reaction kinetics, the apparent activation energy, the gel time, the shear strength and the surface morphology of the impact toughness of composites had been extensively characterized by various analytical techniques. As a result, with the temperature increasing, the gel time of the three adhesive systems has a noticeable decrease and the gel time of MeTHPA epoxy adhesive system was the shortest. The shear strength of T-403 epoxy adhesive system reached up to 30.059MPa. However, the impact toughness of D-230 epoxy composite was the best. The apparent activation energy of those three system were 56.55kJ/mol, 63.99kJ/mol and 67.60kJ/mol, respectively. The reaction order were 0.865, 0.902 and 0.998, respectively.
