Influence of intra-yarn flows on whole 3D woven fabric numerical permeability: from Stokes to Stokes-Darcy simulations

Capillary pressure contribution in fabrics as a function of fibre volume fraction for Liquid Composite Moulding processes

“…The results obtained in the present study are of first interest for composite manufacturing simulation [25,26] and a major concern for complex part and 3D reinforcements [45]. Formulating an analytical description of the change of P cap with V f is thus the next step to be included in further numerical studies along with the understanding and predicting the occurrence of the threshold in further experimental studies.…”

Study on the Permeability Mechanism of Aramid Fiber/Glass Fiber Hybrid Fabrics

“…The data obtained was then used to calculate the permeability in the thickness direction. Aubin Geoffre [18] et al employed a finite element model (FEM) to simulate the Stokes and Stokes-Darcy flows, with the aim of studying the two-and three-dimensional numerical permeability of a fiber medium. Moreover, the effective permeability is closely related to the intramolecular permeability.…”

Instance segmentation of 3D woven fabric from tomography images by Deep Learning and morphological pseudo-labeling

“…Indeed, the composite reinforcement modeling at the mesoscale (in both predictive and descriptive approaches) improves the overall knowledge of textile composite manufacturing in assessing the mechanical response of the textile under various external loads [14,19,49,50] as well as the preform behavior during the forming [15] process. Furthermore, a better description of the textile geometry could also enhance the knowledge of the injection process by determining for instance the permeability of the preform [51].…”
