Registration Date 21-12-2021 Organization National Technical University "Kharkiv Polytechnic Institute" popup.description2  Objects of research: effective thermal conductivity tensor of unidirectional and orthogonally directed fibrous composites; carbon fiber-reinforced composite, which has a linen weave. The aim of the work is to develop joint research activities in the field of vibroacoustic anisotropic metamaterials Fraunhofer LBF (Germany) and NTU "KhPI". Development of methods for numerical homogenization of thermophysical properties of composite materials, solving problems of numerical and experimental determination of mechanical characteristics of anisotropic materials. Research methods - theoretical and numerical methods of homogenization of composite properties. The damping properties of the material are investigated by the Oberst method. Methods of theoretical finding of effective thermophysical properties of fibrous composite materials have been developed. Micromechanical analysis is performed on representative cells by the finite element method. Carbon plastic samples were studied and their elastic and damping properties were determined by calculation and experimental methods. Statistical processing of the experimental results was performed. Comparison of computational and experimental data with numerous calculations is carried out.
