Abstract

In this paper,the epoxy resin system was prepared by applying liquid amine to the modified epoxy resin,which was the mixture of CYD128 and epoxy A.The results showed that the viscosity of the resin system was 255cps at 30℃.It was the moderate temperature curing epoxy resin system.And the tensile strength,tensile module,flexural strength,flexural module of the cured resin product were 67.7 MPa,3.1GPa,101MPa and 2.87GPa respectively.The system can meet the requirement of RTM.
