Using orthogonal experimental design method to study the effect of ratio of curing system,the percentage of vinyl ester resin and an internal ratio of toughening on the vinyl ester resin mechanical properties.Though the test of resin gel time and viscosity characteristics,studied the reactive resin system and the rheology,maked the molding resin curing process.Through the production of cast resin body,testing the strength of the impact and bending.Integrated a variety of factors,selecting a group of formula of the best mechanical properties,impact strength reached 12.27KJ/m~2,nearly 4times than original resins(its impact strength was 3.11kJ/m~2).
