CHEMORHEOLOGY RESEARCH OF VINYL ESTER RESIN FOR RTM

Abstract

Abstract: The chemical rheological behavior of the modified vinyl ester resin system for RTM was studied in this paper. Using DTA and viscosity measuring instruments, the curing characteristics of the resin system and the curing process of the relationship between viscosity and temperature were investigated. According to the rheological properties of resin systems, a Dual-Arrhenius viscosity model with constant temperature was established. The results indicate that, the simulation results were consistent with the experimental results. It has revealed the viscosity variation of the resin system at different temperature conditions, predicted the low-viscosity window with quantitatily, reasonable development of RTM process parameters to ensure product quality to provide the necessary scientific basis.

Key words: vinyl ester resin, curing characteristics, Rheological properties, viscosity model
