The impregnation stage of the Resin Transfer Moulding process can be simulated by solving the Darcy equations on a mould model, with a ‘macro-scale’ finite element method. For every element, a local ‘meso-scale’ permeability must be determined, taking into account the local deformation of the textile reinforcement. This paper demonstrates that the meso-scale permeability can be computed efficiently and accurately by using meso-scale simulation tools. We discuss the speed and accuracy requirements dictated by the macro-scale simulations. We show that these requirements can be achieved for two meso-scale simulators, coupled with a geometrical textile reinforcement modeller. The first solver is based on a finite difference discretisation of the Stokes equations, the second uses an approximate model, based on a 2D simulation of the flow.

Transfer Moulding

This study contributes to the understanding of the mechanism behind process-induced distortions and stresses related to the Resin Transfer Moulding manufacturing process. The objective is to comprehend the phenomena and to identify related parameters. During the manufacturing process, engineering constants of the matrix are changing and are influenced by the existence of a large number of effects. A viscoelastic material model has been derived. This developed material model integrates a dependency of the time–temperature–polymerisation and fibre volume content on the relaxation behaviour of residual stresses in a transversally isotropic reinforced material. The model is validated using a test case on the coupon level and results / limitations are discussed.
