Abstract: The present invention relates to an aerogel composite and a preparation method thereof. The preparation method of the aerogel composite of the present invention comprises the following steps; preparing a hydrophobic gel (step 1); dispersing fiber in a solvent to prepare a solution (step 2); adding the hydrophobic gel above in the solution of step 2 and stirring the mixture to prepare a fiber and hydrophobic gel mixed solution (step 3); separating floc from the mixed solution of step 3 (step 4); and drying the floc (step 5). According to the preparation method of the aerogel composite of the present invention, a high performance aerogel composite having various shapes can be prepared.
