Abstract
A method of optimizing a flow process in resin transfer molding can include the steps of pre-infusing a vacuum-assisted resin transfer mold with a liquid. A sequence of the mold pre-infusion step is detected, from which a flow inhomogeneity adjacent the auxiliary infusion gate is determined. Such a flow inhomogeneity can include, for example, a region where air bubbles can collect, leaving a dry spot in the mold that is not adequately reached by flowing liquid or resin. A resin infusion sequence can then be created, including an opening of the auxiliary infusion gate following a passage of resin therepast to prevent the formation of dry spots.
