Estimation of the thermophysical properties of heat-protective composite materials

“…As a rule, two approaches are used when modeling composite materials: the theory of effective media [20][21][22][23][24][25][26][27][28][29][30][31] and the solution of inverse problems for the identification of thermophysical parameters of composite materials. A modern methodology for solving inverse coefficient problems is proposed in [32][33][34][35][36][37]. The works [38][39][40][41][42][43][44][45][46][47][48][49] also solve direct problems of determining temperature fields in composite materials characterizing by significant anisotropy of properties, using both analytical and numerical methods, as well as describe experiments to determine the properties of composite materials.…”

Synthesis and dielectric properties of metal-ceramic nanostructures

“…This behaviour of multilayer structures can be explained by assuming that the charge transfer in composite layers whose composition is up to the percolation threshold is not through the dielectric phase but through a lower resistive semicon- ductor interlayer. On the other hand, in composites after the percolation threshold, where an infinite network of adjoining metal granules is formed, the channel resistance increases due to the interaction of silicon with the metal phase and the formation of iron and cobalt silicides, which have a higher resistivity than that of pure metals [39][40][41][42][43][44][45][46]. When the thickness of the composite becomes significant, the effect of silicides on the electrical transfer process in (Co45Fe45Zr10)x(Al2O3)1-х after the percolation threshold is reduced.…”

Application of the spherical indenter for determination of the elastic modulus of coatings

“…In the present paper a comparison of different indentation techniques of polymer coatings on steel substrates is carried out on the measurement results. Macro tests were previously conducted for the investigated coatings to determine the bending elastic modulus of coated steel substrates [7][8][9][10][11][12][13][14][15][16][17][18][19]. It was shown that the coatings, despite their small thickness, have a significant influence on the elastic properties of thin steel plate specimens.…”
