Abstract

The microstructure of composite materials of the composition SiC–C is analyzed. It is established that they are a separate group of materials containing a ceramic matrix. The ceramic matrix experiences tensile stresses, as a result of which within the composite material a traditional internal stress field is distorted. The ceramic matrix increases strength at carbon phase boundaries of the composite material, and it reduces porosity. An excess of ceramic material reduces strength and thermal stress resistance. Requirements are provided for porosity of the structure that govern the optimum field of material composition.
