Abstract: The characterization of the cure kinetics and the evolution of the mechanical properties are reported for a thermoset resin material used in wind turbine blade manufacturing. A cure kinetic study was performed using an isothermal Differential Scanning Calorimetry (DSC) technique to characterize the cure rate and to develop a kinetic model to predict the degree of polymerization of the neat resin. Based on the kinetic model, specimens for Dynamic Mechanical Analyzer (DMA) and tension tests were prepared to measure the elastic modulus and tensile strength of the neat resin as a function of cure. The resulting chemo-mechanical empirical relationships can be used to develop micro-scale finite element models for the prediction of the composite strength as a function of cure.
