Effect of heating procedure and gas medium on thermal deformation of fibrous carbon materials

Results of an experimental study are presented as to thermal deformation of fibrous carbon materials depending on the heating rate in various gas media. It is shown that temperature and heating time essentially affect the dilatometric curve character of the given material possessing a considerable deformation property anisotropy in the direction of the basic symmetry axes. Data of gravimetric analysis carried out for appropriate heating rates in oxidative and neutral gas media are presented to account for the character of the obtained curves of the fibrous carbon material temperature deformation
