Investigation of the thermal characteristics of a metal-anisotropic composite contact pair

Abstract

Abstract The tendency to use various composite materials in the production of aircraft components and assemblies determines the relevance of the study of the anisotropic properties of these materials. Ceramic-matrix composites used in aviation rocket and space technology can be assigned certain anisotropic properties already at the production stage. The anisotropy of the material has a significant effect on the thermal characteristics of metal - ceramic-matrix composite contact pairs. This paper presents the results of numerical modelling of the thermal properties of contact interaction with the participation of an anisotropic ceramic matrix composite. It is shown that a change in the orientation of the fibers of the composite matrix with respect to the direction of the heat flux significantly changes the contact thermal resistance.
