Description
Summary:The structure and composition of carbon-ceramic composite FEBUS reinforced with carbon fibers based on viscose, as well as its precursors, are studied using the methods of scanning electron microscopy with energy dispersion analysis and nuclear backscattering spectrometry of 7.5 MeV protons. It is shown that impregnation of the composite precursor with Si (up to ∼30 at %) scarcely leads to siliconizing of the reinforcing fibers. With the stoichiometry of SiC taken into account, the fraction of the carbide component in the composite reaches ∼40%; the remaining ∼60% is the carbon component.
