This is the second paper in a two-part study into the numerical simulation of the light resin transfer moulding (LRTM) process. It focuses on the development of empirically derived models for the permeability and compaction behaviour of Unifilo during light resin transfer moulding. A detailed review of relevant literature allowed identification of important material parameters, and appropriate testing procedures were devised accordingly. Previously published approaches were used to construct light resin transfer moulding specific permeability and compaction models. A material response for each stage of the process was quantified and then inputted into the light resin transfer moulding simulation developed in the Part I of this study. Results were verified using data from an empirical testbed, and the completed light resin transfer moulding model was then applied to a 6-kW wind turbine blade case study to evaluate different infusion strategies and minimise fill time. Finally, it was used to compare the light resin transfer moulding, resin transfer moulding and liquid resin infusion processes for the manufacture of this part.
