The effects of flow channels during Resin Transfer Molding (RTM) process are analyzed using process simulation studies. The flow in channels has been modeled and characterized based on equivalent permeabilities. The flow in the channels is taken to be Darcian as in the fiber preform, and process modeling and simulation tools for RTM have been employed to study the flow and pressure behavior when channels are involved. Simulation on a flat plate indicated that the pressures in the mold are reduced with channels and have been compared with experimental results and equivalent permeability models. Experimental comparisons validate the reduction in pressures with channels and validate the use of equivalent permeability models.
