The objects of the study are samples of porous metal composite materials made of copper fibers and powder and corrosion-resistant steel. The purpose of the work is to determine the permeability and thermal conductivity of the created highly porous composite materials and to study the influence of the characteristics of the macrostructure elements of the material on it. Research methods used in research work - standard methods of research of structural characteristics of metal materials; optical microscopy, thermophysical tests. During the performance of the work - a number of experimental samples of permeable composite materials from copper and corrosion-resistant fibers and powders with different contents of constituent elements of the composite structure were made; - the effect of pressure on the value of the permeability coefficients of these materials was investigated; - the influence of temperature increase on the value of thermal conductivity of experimental materials was investigated.  Product Description popup.authors Guly Volodymyr M Klymenko Lyubov M Remeslo Victor V Rodionova Valentina I Shapoval Iryna V Shapoval Andrii A popup.nrat_date 2023-06-29 Close
