Three-dimensional braided material based on space group P4 symmetry

The invention discloses a three-dimensional braided material based on space group P4 symmetry. According to the braided material, a novel three-dimensional braided geometric structure meeting the space group P4 symmetry and derived by taking representative volume elements meeting point group 4 symmetry as basic structural units is adopted to analyze the motion law of a yarn carrier in a braiding process, and the novel three-dimensional braided material variety having higher fiber volume percentage than the traditional three-dimensional braided material is obtained through research on the technology feasibility and prediction of the fiber volume percentage of the corresponding three-dimensional braided fabric. Meanwhile, the braiding technological method is simple and convenient to implement, the geometric structure of the obtained three-dimensional braided material is more stable, and the mechanical properties are excellent.
