2.5D woven shallow cross bending composites have been widely used in aerospace structures because of their excellent mechanical properties and structural integrity. Correctly characterizing the fiber structure with extrusion or deflection deformation is the key to studying the materials properties in the micro- and meso-scale. The digital element method is an effective way to simulate the internal fiber bundle shape of the woven composites； however， the obtained results depend on the selection of the simulation parameters. Based on the Micro Computed Tomography（Micro-CT） observation of 2.5D woven shallow cross bending SiO2f/ SiO2 composites， a digital element finite element model of the materials is established using the Abaqus software. The temperature load and boundary constraints are applied to the simulation of the fabric deformation process， and the digital element characteristic information after fabric deformation is extracted. Combining the central path and cross-section shape discretization algorithm of the fiber bundles， we obtain the structural shape of the fiber bundles. Analysis of the influences of the selected element type， the elastic properties of the digital element， the number of elements and the friction coefficient on the simulation results determines the main selection principles of the simulation parameters. A geometric model that can reflect the yarn deformation characteristics of the woven composites is obtained， which is consistent with the CT observation results. This method is universal and can guide the digital element modelling of similar fabric composites.
