Abstract
The fabric geometric models based on lamination analogy and stiffness averaging method are utilized to numerically characterize a 2-step braided composite. The model predictions were found to be in good agreement with results of mechanical tests performed in this study. The architecture of this material is investigated by identifying the geometric and braiding process parameters which include the linear density ratio between axial and braider yarns, the pitch length of braider yarn, the aspect ratio of axial yarn, and the aspect ratio of braider yarn. Parametric study showed a wide range of variability in the elastic constants of the composites. Results of the elastic properties are presented in the form of performance maps.
