|Summary||During Metal Matrix Composites (MMCs) processing by injection or squeeze casting method, the fibrous preform can be damaged on account of high liquid injection pressure. In this paper, a one-dimensional numerical simulation of a liquid infiltration through a deformable preform is presented. First the physical model and resolution algorithm are described. Then some numerical results are presented : the influences of injection rate and capillary pressure on injection pressure and preform deformation are studied. Finally, a conclusion is given which presents possible developments and applications of this simulation in more realistic cases.
