The invention provides a zirconium oxide-aluminum oxide composite fiber aerogel material and a preparation method thereof. The method comprises the following steps of: preparing a polymer solution: adding 2-30 parts by weight of a polymer material into 100 parts by weight of a solvent, and performing stirring and dissolving for 0.1-10h at a temperature of 25DEG C-100DEG C and under a rotating speed of 50-1000rpm to obtain the polymer solution; preparing a spinning precursor solution: adding 5-1000 parts by weight of a zirconium oxide precursor and 1-300 parts by weight of an aluminum oxide precursor into the polymer solution to obtain a spinning precursor solution; performing solution jet spinning: spraying the spinning precursor solution from a spinning nozzle by using compressed air to deposit fibers on a receiver, thus obtaining a composite fiber aerogel material; and performing calcining: calcining the composite fiber aerogel material. The preparation method provided by the invention adopts the ceramic precursor to prepare the composite fiber aerogel material through a solution jet spinning method, is simple in preparation process and high in efficiency, and has a good industrial application prospect.
