Molds, computational fluid dynamics

Hence, CFD (Computational Fluid Dynamics) simulation techniques are adopted as predictive method for resin flow to design the RTM molds and to determine the vent locations in the molds. Accurate prediction of the resin flow through the preform inside the RTM mold is one of the most critical aspects of RTM simulation program. Permeability properties of the textile preform to a great extent influences the resin flow during the RTM process.
