Investigations for the Numerical Determination of the TTT-Diagram for Unsaturated Polyester Resin Systems

摘要

During cure of a thermoset resin, the material exhibits three distinct phases: liquid, gel, and solid. Each of these material states is marked by dramatic changes in the thermomechanical properties of the resin. The glass transition temperature and the elastic modulus of the thermoset materials are two examples of the material properties that are of great interest to processors in the thermoset resin industry. The ability to predict the progression can give insight into the performance and optimisation of processing methods for thermoset resins.
