METHOD FOR PREPARING CONTINUOUS FIBER-REINFORCED CERAMIC MATRIX COMPOSITE BY FLASH SINTERING TECHNOLOGY
The present disclosure discloses a method for preparing a continuous fiber-reinforced ceramic matrix composite by flash sintering technology, including: placing a continuous ceramic fiber preform in a mold, adding a nano-ceramic powder, and subjecting the resultant to mechanical oscillation and press forming in sequence to obtain a green body; heating the green body to a preset temperature and applying an electric field with a preset electric field intensity, until occurrence of flash sintering; and converting a power supply from a constant voltage state to a constant current state, holding at the temperature and cooling to obtain the continuous fiber-reinforced ceramic matrix composite.
