Abstract

In this study, a 2-D Darcy’s law based numerical model is developed in order to investigate the effect of saturation on the propagation of the resin in the die chamber of a pultrusion line. The numerical model is established using the finite volume method and alternating direction implicit scheme. The implemented saturation and relative permeability curves are adopted from relationships presented in the literature. The results of the numerical model highlights the importance of accurately determining thesaturation curve when included in a numerical solver that is used to predict the resin flow in injection pultrusion. Further research is planned within this field in order to identify realistic saturation curves for fiber reinforcements used in resin injection pultrusion.
