Paper Abstract

This paper presents the results of Finite Element modeling and experimental investigation of mold filling in an RTM process. Flow measurement experiments were designed to verify the results of the numerical models. Flow experiments in molds having cavities of rectangular and irregular shapes were performed to investigate resin flow behavior. Silicone fluids of 50 and 100 centistoke viscosities as well as EPON 826 epoxy resin were used in the mold filling experiments. Fiberglass and carbon fiber mats were used as reinforcements. Numerical models were developed to simulate resin flow into the mold cavities. The resin flow through fiber mats was modeled as a flow through porous media. The effects of injection pressure, fluid viscosity, type of reinforcement, and mold geometry on mold filling times were investigated.
