description The invention relates to a method for preparing a continuous fiber reinforced ceramic-based composite material by using a flash sintering technology, which comprises the following steps: firstly, putting a continuous ceramic fiber preform into a mold, and then gradually pouring a small amount of nano ceramic powder into the continuous ceramic fiber preform in the mold for many times; through mechanical oscillation, fully filling pores in the preform with nano ceramic powder; carrying out compression molding on the obtained loose composite material by adopting a certain pressure to obtain a green body; putting the green body into a flash furnace, heating to a preset temperature, and applying an electric field with preset electric field intensity until a flash phenomenon occurs; and then converting the power supply from a constant-voltage state to a constant-current state, carrying out heat preservation for a period of time under a preset current density, and finally, carrying out cooling to obtain the continuo
