STUDY ON VISCOSITY MODEL AND RHEOLOGICAL PROPERTIES OF UPR APPLIED IN VARI PROCESS

Abstract

Abstract: This paper tested and analyzed the viscosity of DS326PT-1 resin system under dynamic temperature and constant temperature,established the engineering viscosity model and predicted the VARI processing window according to the viscosity model. The results indicated that the experimental viscosity value agreed well with the predicted viscosity,which proved the validity of the model. The viscosity model of the resin system can provide important data for the simulation and parameter optimization of VARI processing.

Key words: VARI, rheological behavior, engineering viscosity model, processing window
