We recently developed a simulation tool to simulate a quite wide class ofcomposites manufacturing processes based on a compressible porous media theory formulationinvolving three constituents, solid, fluid and pore gas embedded in the voids. The aim of thistool is: firstly to model the highly deformable preform and its interaction with external loadingand the intrinsic fluid pressure as well as the resulting changes in permeability, compaction andlevel of saturation. Secondly, the aim is to track the resin flow front during the infusion processusing the continuum formulation itself, thereby avoiding methods like level set
