Effect of Porosity on Some Characteristics of Carbon-Carbon Composite with Coal Tar Pitch and Combined Coal Tar Pitch-Pyrocarbon Matrix

摘要

The principles of changes in the structure, porosity, thermal conductivity, and strength of a two-dimensional reinforced carbon–carbon composite at different stages of the liquid-phase compaction by coal tar pitches with subsequent carbonization as well as the gas-phase pyrolytic compaction have been investigated. The analysis of effectiveness and the mechanism of the influence of various types of compaction on the properties of the material has been performed.
