| Abstract: | The definition of 2.5D braiding process was introduced. Geometric models on microstructures of 2.5D braided composites were summarized and compared. A reviw of theoretical calculations and numerical simulations on the elastic properties prediction of 2.5D braided composites were given. Finally, the influences of microstructures and warp or weft densities on fiber volume fraction and elastic properties were analyzed, respectively. |
