Modelling the Resin Infusion Process, Part I: Flow Modelling and Numerical Investigation for Constant Geometries

An important class of production processes for fibre reinforced plastics are flow processes (e.g. RTM, VARI). The simulation of flow processes with textiles deforming during the process is a big challenge. Therefore it is difficult to embed conventional approaches in industrial environments. This two parted paper shows a new approach for modelling of these processes with deformable geometries: analogies to thermomechanical relations are applied to achieve this aim. In this first paper the approach is derived for constant geometries and its numerical properties are investigated. A shape factor determines the deviation to analytical solutions. This deviation can be described as a function which is used to derive an extrapolation method for an efficient filling simulation.
