Abstract: Resin Transfer Molding is one of the most common fabrication methods for composite materials. It is attractive for high performance and low cost manufacturing of polymer composites. In this paper, the Control Volume Finite Element Method (CVFEM) was applied to simulate RTM mold filling. The computational formulas of triangular and quadrangular elements were presented for details. Some case studies were conducted. The results showed that the quadrangular element has higher computational performance than the triangular element and can be used with the triangular elements.
