The use of composite materials in large structures has increased in recent years. Aircraft industry has recently begun to investigate the field of Liquid Composite Molding (LCM) through research programs because of its ability to produce large parts at low cost. The resin motion through the fibrous perform is described using Darcy's law and mass conservation. The 3D flow is solved numerically using the Boundary Element Method (BEM). The simulations are performed using an updated lagrangian mesh in isothermal conditions. The numerical model is assessed by comparing computed results with the analytical solution in the case of radial injection from a spherical inlet.
