Abstract: A theoretical model for the 1-D flow of a resin-like liquid in the naturalfiber fiber mats of resin transfer molding (RTM) mold is proposed. After assuming the porosity and the permeability to vary only a function of time, a theoretical formula for the front location is proposed after employing an altered form of continuity equation (which takes into account both the liquid absorption and the fiber swelling) and the Darcy’s law for the single-phase flow. A comparison of the theoretical predictions with the experiments reveals that the variable permeability model offers a better match viv-a-vis the fixed permeability.
