Abstract: A three-dimensional geometric description for a large range of two-dimensional woven architectures is proposed which can serve as a basis for stiffness and strength modelling of fabric composites. We introduce a strict logical scheme for calculating the full geometry of a general yarn architecture. First, a library of 108 rectangular macro-cells has been put together to build complex material unit cells. This complexity is caused by the yarn interlacing style and the existence of different yarn sizes in the fabric composite. Next, each macro-cell is divided in a number of micro-cells. The geometric model, based on a lenticular yarn cross-section, predicts the weave cover factor, the global and local fibre volume fractions and the yarn orientations. Moreover, a logical and simple meshing for each woven structure is created. A Microsoft Excel(R) application (TEXCOMP) has been developed to transform the model into a useful design tool.
