Fabrication of SiC/C Functionally Graded Material

    Graphical Abstract
    • Abstract
  • The thermal stress in SiC/C FGM in steady temperature field was analyzed based on the classical lamination theory and thermo-elastic mechanics. The optimum composition distribution parameters for fabricating SiC/C FGM were obtained through the above analysis. SiC/C FGM F4 and F7 were fabricated successfully by hot pressing. The microstructure was observed by SEM. Thermal shock resistance of SiC/C FGM was repeatedly tested by quenching from 500℃ into water with room temperature. It has been proved that FGM F7, which was fabricated with the optimized parameters, has better thermal shock resistance.
