Simulation du préformage de renforts composites textiles 3D
Published online by Cambridge University Press: 19 October 2010
Abstract
Ce travail s’inscrit dans le cadre de la simulation de la mise en forme de matériaux composites. Le cas traité ici est celui du préformage des interlocks. Il s’agit de renforts textiles 3D permettant d’éviter le délaminage rencontré avec des stratifiés. Un élément-fini 3D semi-discret permettant de modéliser la déformation d’une préforme interlock complète est décrit. Chaque élément tridimensionnel contient des fibres qui contribuent à la rigidité de l’élément. Les paramètres matériaux sont identifiés à partir d’essais mécaniques et la simulation est validée par comparaison avec l’expérience.
