Studies on Rheological Behaviors of Bismaleimide Resin System for Resin transfer Molding

摘要

the rheological behavior of bismaleimide resin for resin transfer molding (RTM) was studied with DSC analysis and viscosity experiments. A rheological model based on the dual-Arrhenius equation was established and used to simulate the rheological behavior of the resin. The model predic- tions determined from the dual-Arrhenius equation were in good agreement with experimental da- ta. The processing window of the resin system can be well determined based on the developed mod- el. The rheological model is important for processing simulation and quality control of RTM processing for high performance composites.
