Composite materials offer a lightweight structural alternative to the metals traditionally used in the aeronautical and automotive industries, leading to fuel savings that reduce the carbon footprint and increase overall performance. Naturally, this replacement of the base material comes with different manufacturing processes, where specific mechanics take place.Liquid composite moulding processes for dry textiles [1]…

Keywords : solid-beam, hyperelastic, mesoscopic scale, fibrous finite element Background Finite element analysis of meso-scale textile reinforcement models faithfully reproduces defects like yarn buckling or gapping during the forming processes. They are often based on accurate geometric models very finely meshed or high-order interpolation elements. It leads to high fidelity results regarding experiments, but also…

Study of the bending behavior of reinforcements during the shaping process of composites La variabilité des propriétés des matériaux composites est l’un des principaux freins à leur utilisation. Elle est principalement due à l’hétérogénéité du matériau ainsi qu’aux défauts de mise en forme. Cette étude s’inscrit dans la recherche de la maitrise des défauts liés…
