| Abstract: | A unit cell geometrical structure was found using symmetry operations corresponding to the point group S6. Based on the symmetry of space group P3 , a 3D braided geometrical structure was obtained by transforming the unit cell. The features corresponding to this braided structure were studied. The fiber volume percentage and variational tendencies of the material were predicted by establishing a geometric model. |
