**Abstract**
 The aim of this research was to predict the effect of multiple resin injection ports on the magnitude of the resin injection pressure needed to achieve complete wet-out of the fibres in the injection chamber. The work focuses on the use of epoxy/glass rovings and polyester/glass rovings composites. The recommended injection pressures for complete wet-out are predicted for a variety of processing parameters. Darcy's law for flow through porous media is used for modelling the fibre/resin system of injection pultrusion. The governing equations are solved via the finite element volume method to predict the resin pressure field, the resin velocity field and the location and shape of the resin flow front. Different permeability models were used to determine the transverse and longitudinal permeabilities. 7 refs.
