| Abstract: | The curing properties and chemorheological behaviors of LSP-8020B unsaturated polyester resin system were studied with DSC analysis and viscosity experiments.A rheological model based on the engineering viscosity equation which was in good agreement with the results of experiments is established and used to simulate the rheological behavior of LSP-8020B resin system.The processing window of LSP-8020B resin system can be well determined based on the developed model.The rheological model is important for vacu... |
