Abstract

The properties of resin system are of great importance to the Resin Transfer Molding technology. To explore a new type of RTM resin, we choose the mid temperature epoxy/modified imidazole system. The monograph includes the processing characteristics investigated with the use of viscosity meter DSC 7 and the mechanic properties obtained by MTS. It is demonstrated that the system of epoxy/modified imidazole is suit for RTM when the resin/curing agent proportion is 100∶6 100∶8. Also, the mid temperature system maintains a viscosity well under 100 mPa·s when the temperature is above 70 ℃. Besides, the tensile modulus of casting body is as high as 3.7 GPa. Both the viscosity features and the mechanic properties are fit for RTM technology.
