To tend to reduce costs of composites forming process, it is necessary to have at one's disposal a simulation tool and a good knowledge of the behavior models, likely to be used. Several approaches related to the various scales of the woven brous mediums are analyzed ; the construction of constitutive laws for these mediums depends closely on the directional properties induced by each family of fibers.An experimental and a numerical analysis of doubly curved parts stamping are carried out : stamping of dry woven reinforcements and thermoforming of pre-impregnated thermoplastic composites are performed. The objective is, in the first case, to observe the deformation mechanisms concerned and to measure some characteristic sizes, and in the se...
