The characterisation of a powder-epoxy resin has been carried out using differential scanning calorimetry (DSC) and parallel-plate rheometry, for both isothermal and dynamic conditions. The powder-epoxy has been identified as a candidate material for the cost-effective manufacture of thick composite sections in marine renewable energy (MRE) applications. The objective of this research was to investigate the powder-epoxy under different processing conditions, with the overall aim of developing a numerical resin flow model that can optimise material processing and ensure that high quality manufacturing is achieved. The experimental sets of data for DSC and rheometry have been fitted to a cure kinetics model and a chemorheological model, respectively. The cure kinetics model was implemented as a predictive tool in the chemorheological model in order to simulate the change in viscosity due to curing. Good initial results were achieved for both models; however, shortcomings in the experimental and theoretical methodologies were identified and outlined, and will be accounted for in future work.
