Flow modeling in composite reinforcements
E. Ruiz and F. Trochu, École Polytechnique de l’Université de Montréal, Canada
Abstract:
In composite manufacturing by resin injection through a fibrous reinforcement, several phenomena occur involving the flow of resin driven by capillarity, gravitational or pressure forces. In order to study the manufacturing of pieces of complex shape made by liquid composite molding (LCM), a numerical simulation of the mold-filling process is required. Numerical process simulation can be done by combining classical finite element techniques to a flow-tracking approach which allows the movement of the resin flow front through the finite element mesh of the part. In this chapter, the techniques for computing ...
