Meso-FE modelling of 3D five-directional braided composites
Microstructure is necessary to study the mechanical properties of 3-dimensional (3D) five-directional braided composites accurately. By analyzing the photomicrographs and the space geometry position of yarns, the transformation of the axial yarns sections and the yam packing factor are both considered, the mathematical relationship between the geometry of the unit cell and the braiding parameters are derived. A 3D solid unit cell is established by using the CAD/CAE software Pro/E. The mechanical behaviors of 3D five-directional braided composites are predicted by 3D finite element analysis (FEA). The results of the elastic modulus are correlated well with the experiment dates available.
