Simulation Numérique de la Fabrication de Composites À Renfort Fibreux 3D Par Le Procédé D'infusion

Résumé du livre

The manufacture of composite aeronautical structural parts requires the use of more complex reinforcements, especially the 3D reinforcements. Resin infusion is the key process of Liquid Composites Molding (LCM) which will determine the quality and cost of the parts. The target of this thesis is to develop models at different scales of fibrous network of the reinforcement and to propose a finer numerical simulation of the infusion process. The influence of the 2D and 3D reinforcement structures on the infusion process will be studied at the different scales: micro (intra-tow), meso (inter-tows) and macro (reinforcement, part).
