Abstract Based on the basic principles of the four-step method (1×1) weaving technology, a detailed analysis is conducted on the
periodic motion of the yarn carrier and the trajectory of the yarn in space during the weaving process. Utilizing Matlab software, two
binary variables are defined to track the regular movement of the yarn carrier in a programmatic form. Based on a series of hypotheti‐
cal conditions for the yarn, the internal structure of three-dimensional woven composite materials is represented using an inner cell
characterization, and a three-dimensional four-directional structure unit cell model is established. Meanwhile, by providing the spa‐
tial coordinates of the yarn, the modeling of the three-dimensional woven composite material preform is completed using Texgen
software.
