THE RESEARCH OF MODIFIED VINYL ESTER RESIN SYSTEM FORMING PROCESS AND PROPERTIES IN RTM

Abstract

Abstract: Preparing three kinds of vinyl ester resin for RTM,named R-1,R-2,R-3. studying their curing reaction characteristics,process characteristics and mechanical properties of resin-cast body. Three kinds of resin systems under the low viscosity at room temperature (25℃) ,respectively 350mPa·s,80mPa·s,70mPa·s,The viscosity of a certain temperature is the below of 500mPa·s,and has a longer period of application,in line with the requirements of RTM injection process. Analysis of the mechanical properties of resin cast body,the bending strength of up to 110. 05MPa,the impact strength of up to 12. 27kJ /m² . R-3 for the final selection of the best overall performance resin system.

Key words: RTM, VE resin, viscosity, bending strength, impact strength
