Abstract
This article proposes new analytical dependencies for determining the thermal conductivity of materials reinforced with bars. Thermal conductivity is determined in the direction parallel to the axis of the bars. According to the RVE method, a minimal representative volume is selected in the original reinforced material, in which the thermophysical properties of the original material are reproduced. Based on Fourier's law, analytical dependences are derived to determine the effective thermal conductivity of the reinforced material with bars. The effective thermal conductivity is affected by both the thermal conductivity of basic materials and geometric parameters of the reinforcement. As part of the study, numerical simulation of the thermal conductivity process in cement reinforced with polymer bars was carried out using the ANSYS software package. Graphical dependences of the effective thermal conductivity of the reinforced material depending on the bar diameters are built.
