- Abstract
- Products from the carbon-carbon composite materials (CCCM) are of considerable interest to use in the aviation and space industry that sets a task of fuller studying of their heat physical properties and behavior in the conditions of high-intensity heating. For calculation of temperature fields is offered to use the new approach based on the integral equations of thermal conductivity, which make it possible to estimate the accuracy of the carried-out calculations and uniformly take into account the various inhomogeneity of material - his microstructure and type of weaving of carbon fibers. It is noted that use of "effective" (average) coefficients of heat conductivity, at modeling high-intensity thermal influence doesn't give the chance fully to study distribution of temperatures on of thickness material from CCCM. The software developed by the author, allows not only to carry out model calculations for definition of the field of temperatures on bearing layer thickness (two-dimensional model), but also to choose a necessary configuration of weaving of fibers, and can be considered as the effective tool for receiving the required technical characteristics of a final product.
