Meso-Macro Simulations of the Forming of 3D Non-Crimp Woven Fabrics

The RTM (Resin Transfer Molding) manufacturing process is largely used for the fabrication of textile composites. During forming phase, deformations composite reinforcements at mesoscopic scale, such as positions, orientations, and changes in sections deformed yarns, are essential to calculate permeability reinforcement injection phase evaluate mechanical behaviors final products. However, models simulation lead a high computational cost due numerous yarns their complex contacts, especially thick reinforcements. In this paper, macro-meso method predicting with reasonable calculation time presented paper. proposed multi-scale allows linkage macroscopic modelling an RVE (Representative Volume Element) through embedded approach. Based on simulations using 3D hyperelastic constitutive law, geometry first deduced. solution can excessive extensions yarns. To overcome inconvenience, local based analysis carried out single RVE. Finally, investigated comparison experimental results, illustrating efficiency method.
