Abstract

In the course of this study, the simulation of the resin flow in the RTM process is developed by the control volume finite element method (CVFEM) coupled with the equation of the free surface location. This location is made by means of the so called "Volume of Fluid" methods or VOF. Thus, the position of the flow front, the time-lapse and the rate of the non saturated zone are calculated at every step. Our results will be compared with the experimental and analytical models in the literature. On the whole, our study is concerned with the simulation of the thermally insulated filling of moulds in RTM process while adopting the CVFEM and VOF method, taking into account the presence of obstacles, coupled with the thickness variation effect and the reinforcement coats.

<abstract xml:lang="en">In the course of this study, the simulation of the resin flow in the RTM process is developed by the control volume finite element method (CVFEM) coupled with the equation of the free surface location. This location is made by means of the so called "Volume of Fluid" methods or VOF. Thus, the position of the flow front, the time-lapse and the rate of the non saturated zone are calculated at every step. Our results will be compared with the experimental and analytical models in the literature. On the whole, our study is concerned with the simulation of the thermally insulated filling of moulds in RTM process while adopting the CVFEM and VOF method, taking into account the presence of obstacles, coupled with the thickness variation effect and the reinforcement coats.</abstract>
<abstract xml:lang="fr">La présente étude porte sur la simulation du remplissage isotherme des moules en procédé RTM, en adoptant la méthode CV/FEM et VOF, avec prise en compte de la présence d’obstacles couplée à l’effet de la variation de l’épaisseur et des couches du renfort. Les codes développés ont pour objectif d’optimiser le positionnement des points d’injection, des évents et déterminer les pressions d’injection optimales pour minimiser les temps de cycle. Ces codes utilisent un mailleur propre à l’équipe permettant de discrétiser le domaine en éléments triangulaires non structurés avec possibilité de raffinement local et d’inclusion d’inserts.</abstract>
