Abstract

In this paper we adapt and extend the results of a recently developed continuum mixture model to study wave propagation interaction with plain weave textile composites. The original model, which was first used to study wave propagation in bilaminated composites, is based on approximate distributions for some of the transverse stress and displacement components. This results in two coupled partial differential equations describing the micromechanical behavior of the layered composite. Next, we idealize the complex weave unit cell into segments of bi-laminated composite, which geometrically model the undulation. Formal solutions for the two coupled equations are then obtained in each of the segments. Finally, the transfer matrix method is used to relate the solutions at one end of the idealized unit cell to the other, to obtain the unit cell global transfer matrix and to derive the dispersion equation of the system. The procedure is applied to a graphite-epoxy plain-weave composite and several characteristics are observed. Very good convergence is achieved using only a small number of segments.
