Resin transfer modeling (RTM) offers many advantages over handlay-up of prepreg or wet filament winding in the production of advancedcomposites. Successful application of RTM requires complete resininfiltration of the molded dry fiber preform. Uncertainty in the resininfiltration process due to variance in preform permeabilities has resultedin long process development cycles. High rejection rates, and reduced scopeof part configurations that can be processed using RTM. This project willexamine methods for in-situ monitoring, and control of resin flow will bedeveloped and feasibility of the techniques will be demonstrated.
