It is devoted to a theoretical explanation, description and experimental verification of certain phenomena related tothe material parameters governed by the manufacturing processes such as the volume fraction of phases, crimp waveform deformation when pressed during the manufacture, initial defects and cracks in the matrix and yarn phases caused by shrinkage duringcarbonization, and cracks resulting from misfit of thermal properties between fibers and matrix. The random character of microstructure on both micro- and meso-levels and its influence on the overall response of composite structures is the main subjectof this research project. To that end, a powerful image analyzer LUCIA that allows transformation of color images into their binary counterparts will be used. The carefully processed images of real composite samples will be used to identify the basic"@en .
