【 摘 要 】

In this paper, the effective elastic characteristics of spatially reinforced composite materials is calculated. The problem is solved by the finite element method in the Ansys Workbench software using the periodicity cell of the material. When constructing the model, were considered the weaving scheme, the volume fraction of the reinforcing skeleton, and the geometric shape of the reinforcing filaments. The effective elastic modulesare determined by the volume averaging method. To obtain nine independent characteristics of the orthotropic material, six calculation modes were used: tensionalong the axis and ashear in the planes. The stress-strain state of reinforcing filaments is analyzed.
