Abstract:
Iranian coal tar pitches include AP63, AP14, MSP and HSP with their fractionation and Natural pitch characterized by carbon yield, density, viscosity, fractionation with solvents, and thermal treatment type using TGA tests. TGA results show characteristic differences in pyrolysis behavior of coal tar pitches, natural pich and fractionation of the pitches. The suitability of these commercially available matrices for densification of 3D C/C composites was examined by a low-pressure impregnation/carbonization process. Best Iranian pitch selected in terms of theoretical result. Data measured after impregnation indicated that using chosen type of pitch results in a density higher than other types.
