An improved unit cell model for 3Dfour-directional braided composites was proposed,considering the cross-section shape variation of interior fiber bundles along their center line in manufacturing process of jamming action,and this model was further used to predict equivalence elastic constant.Firstly,based on analyzing the braiding process,interior fiber bundle distribution of unit cell was established;then,the geometric position coordinates for fiber bundle jamming regions of improved unit cell model were ...
