The comparative analysis of coefficients of correlation, correlation functions real and various model both traditional, and new multilayered polydisperse fibrous structures is carried out. The method of correlation polydisperse components by which new analytical decisions for tensors effective are received is developed is transversal isotropic electro magneto elastic properties of real unidirectionally fibrous structure in correlation approach of statistical mechanics of composites. Numerical calculation of factor of electromagnetic relationship for fibrous piezocomposite ferrite/PVF is given.
