Woven composites with basalt reinforcement plain 1x1 are examined to define structural mechanics. Woven composites were created by the prepreg technology, 8 layers of plain-weave basalt fabrics were saturated by the precursor, polysiloxane matrix Lukosil®, and joint pressed during temperatures of 200°C and 600°C. The yarns consist of 8000 fibres assembled without twisting. Voids complete entire structure. Elementary woven cell was defined from binary images using flim2curve and contour functions of COMSOL Multiphysics®. This is time consuming process, because it is necessary to define points and subdomain. Reorganization of the yarns during composite manufacturing seems to be a very important phenomenon for mechanical behaviour.
