The properties of bulk graphite and carbon-carbon (C/C) composite products, including their mechanical and electrical properties and thermal conductivity, may be determined by not only the size, content, shape, and dispersion of the filler materials but also by the crystallographic structure of the binding materials [1,2]. As the substituent hydrogen is removed during the carbonization process, an organic binder is converted into a carbonaceous material, specifically an aromatic carbon molecule in which large polycyclic aromatics are stacked. Reports have shown that a thermal treatment of carbon materials at a temperature exceeding 2500°C converts the crystal structure into a graphite structure or a graphite-like structure, indicating that the crystallinity of the resulting structure is higher at a higher thermal treatment temperature [3,4].
