Meso-modeling of 3D Woven Composites

In the recent years, due to the rapidly developing textile technology, the 3D woven composites have attracted significant attention with their superior delamination resistance compared to the unidirectional (UD) and biaxial (2D) woven composites. With the reinforcing tows along the Z-axis, these composites eliminated bonding of plies with stitching and z pinning that have been damaging the internal structure, and adhesive bonding processes, which has been applied so far. In this project students In this the meso-scale finite element models will be initially established in CAD, by using the geometric data extracted from the microscopic inspection of the inner structure through the polished sections. The geometrical data will include the varying cross sectional area values, the height, width and contour shapes of the fibrous yarns.
