Textile composite materials represent a vital class of materials utilized in aerospace structures. There are many potential advantages to using 3D woven composites including near-net-shape preforms, potentially lower cost for complex shapes, through-thickness property tailoring, and higher delamination resistance. These composites introduce additional geometric complexities compared to 2D textiles and unidirectional composite materials. Predicting the performance of such composites requires explicit consideration of the fiber tow architecture, i.e., mesolevel analysis ​
