In this study, two mesomechanical models, inclusion model and inclusion element model, based on equivalent inclusion method and predictive software tools for the mechanical properties of textile composites have been developed. As the inclusion model, the Mori-Tanaka method and the self-consistent method were employed. The Mori-Tanaka method is fast, good overall accuracy in the low to mid volume fraction range as almost the same as the self-consistent method in which an accurate algorithm has been used for the evaluation of Eshelby’s tensor for anisotropic media. But they loose some micro structural information as yarn segment positions and are not considered in the micromechanics analysis. On the other hand, the inclusion element model can take account of positional information of yarn segments, it is very useful model which covers the imperfection of the inclusion model, insofar the fiber volume fraction is accurately sampled but they need significant sampling times and also need more intensive computational power. Calculation of the mechanical properties using the inclusion element model by homogenization method revealed that the inclusion element model overestimates the elastic properties of out-of-plane because of unconsidered resin plies between adjacent yarns.
