Investigation of mechanical properties of polymer composite material based on polyethylene with Fe2O3 nanoparticles

Estimation of the thermophysical properties of heat-protective composite materials

“…It is important to note that the properties of thermal protection tiles (thermal conductivity, density, strength, and thermal expansion coefficient) are determined primarily by the fibers -their composition, structure, morphological features, etc. [1][2][3][4][5][6][7][8][9][10]. There is a sufficient number of works on obtaining and studying the thermophysical and mechanical properties of composite materials [11][12][13][14][15][16][17][18][19].…”

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.…”
