description The invention belongs to the technical field of superhard compounding, and particularly relates to a silicon carbide whisker modified boron nitride composite material, a preparation method and application thereof, a boron nitride complex and a preparation method thereof. The invention provides a preparation method of a silicon carbide whisker modified boron nitride composite material, which comprises the following steps: mixing a boron nitride aqueous dispersion, a first alcohol solvent, an alcohol solution containing a silicon source and a pH value regulator, and carrying out hydrolysis reaction to obtain silicon dioxide coated boron nitride; and mixing the silicon dioxide coated boron nitride with a carbon source, and calcining to obtain the silicon carbide whisker modified boron nitride composite material. The silicon carbide whiskers grow on the surface of the boron nitride in an in-situ growth mode, and the obtained silicon carbide whiskers and boron nitride have good bonding performance and dispersity.
