Abstract

The application of the Mori–Tanaka method for the calculation of the elastic properties of textile composite materials is studied. First, it is shown how the implementation of the Mori–Tanaka method for materials with a complex orientation distribution can be greatly simplified by the use of orientation tensors. For inclusions with elliptical cross-section, a new concept of “equivalent orientations” is defined to simplify the implementation of elastic models. Second, the Mori–Tanaka method is used to predict the in-plane elastic properties of various types of woven, braided and knitted fabric composites. Especially for knitted fabric composites, the Mori–Tanaka method clearly predicts the elastic properties better then the classical Voigt method. Besides, Mori–Tanaka offers some interesting perspectives for damage and strength modelling of textile composite materials.
