In this article, a method for wave propagation analysis of textile composites at a mesoscopic level is presented for the first time. This study is performed in the vibro-acoustic and ultrasonic frequency ranges. The presented method combines a mode-based reduction method, allowing for great CPU cost saving, and the Wave Finite Element Method (WFEM), which associates the Periodic Structure Theory (PST) and standard Finite Element Method (FEM). The PST allows to analyse the wave propagation properties of a periodic structure by modelling only a periodicity (unit cell) of it. A standard wave propagation analysis of textile composite structures is also performed, using homogenized properties in the unit cell, and used as a comparison. It is shown for different types of textiles that using the standard method results in errors in the dispersion curves.
