Cure Kinetics and Rheology Models for ICI Fiberite 977-3 and 977-2 Thermosetting Resins
Source abstract
Abstract
Heat of reaction, degree of cure, and viscosity of ICI Fiberite 977-2 and 977-3 thermosetting resins were measured. Degree of cure and viscosity for Fiberite 977-2 and 977-3 resins was determined under isothermal and adiabatic conditions. Expressions relating the degree of cure and viscosity to the time temperature profile during processing were found for each resin. Typically, these relationships are determined by conducting isothermal tests at several temperatures. A new approach which employs adiabatic data is proposed. A comparison of the isothermal and adiabatic based models is presented for both cure and viscosity data. The adiabatic based models require fewer test runs to develop the model parameters, yet accurately predict resin cure and viscosity characteristics.
