The invention relates to a high-temperature-resistant composite component aerogel material and a preparation method thereof. The method comprises the following steps: preparing a nano oxide dispersion liquid; uniformly mixing the oxide dispersion liquid and an adsorbent through high-speed shear stirring and ultrasonic treatment to obtain a mixed solution; placing the solution in a closed container for high-temperature hydrothermal reaction to obtain a semi-solid gel block; the high-temperature-resistant composite component aerogel material is prepared by the following steps: firstly, carrying out low-density silica sol precursor dipping treatment, aging and drying, then carrying out a heat treatment process, then carrying out a chemical vapor deposition process and carrying out high-temperature cracking, thereby obtaining the high-temperature-resistant composite component aerogel material. According to the preparation method, the high-temperature-resistant composite component aerogel material which can resist
