Abstract

In this paper, a mathematical model of resin flow through fiber reinforcements in compression resin transfer molding (CRTM) is presented. Before complete closing of the mold, the preform is partially filled by resin during the injection phase. Then it is compressed by the mobile part of the mold. The resin flow in the fiber bed is governed by Darcy's law. The consolidation of the saturated preform is described by the total mass conservation. It is assumed that in the resin-saturated domain the total stress is equal to the sum of the fiber bed stress and the resin pressure. A filling algorithm based on resin conservation on a deformable grid is used to advance the flow front at each time step. The model presented in this
