Abstract | Though-thickness and in-plane flow simulations for 3D woven carbon fibre fabrics were performed based on TexGen geometrical modelling, with meshing and CFD analysis in Ansys CFX. As a first approximation, a unit cell representing 3D woven fabric geometry was generated in an automated manner in TexGen from a set of experimentally determined geometric parameters. Appropriate meshing and application of periodic boundary conditions, through-thickness and in-plane flow were analysed using CFD simulations. The predictions were compared with experimental permeability measurements. A model generated based on average measured fabric geometry parameters allows the permeability in through-thickness and in-plane warp directions to be predicted with satisfactory accuracy, while the inplane permeability in weft direction is underestimated. CFD analysis was used to investigate the effects of fabric geometric variability on permeability. It was found that the weft yarn cross-section has the most significant influence on the permeability in all fabric directions. The analysis also suggests that the main flow direction is strongly related to crimp of the weft yarns caused by the binder. |
