The invention provides a reinforced aerogel composite material and a preparation method thereof. The reinforced aerogel composite material comprises single aerogel or two aerogels or more than two aerogels, the surfaces or block interfaces of the block aerogel are coated or bound into a whole by virtue of fiber mesh fabric-reinforced waterborne adhesive. The preparation method of the reinforced aerogel composite material comprises the following steps: (1) carrying out hydrophobic modification treatment on the surfaces; (2) carrying out hydrophilic/hydrophobic modification treatment on the surfaces; and (3) preparing the reinforced aerogel composite material: uniformly coating the surface of the block aerogel or the interface of two aerogels with waterborne adhesive and fiber mesh fabric and curing to obtain the reinforced aerogel composite material. The reinforced aerogel composite material provided by the invention has the characteristics of excellent thermal-insulation property, heat preservation property, sound insulation property, fireproof property, explosion resistance, shock absorption, energy absorption, light weight, better mechanical properties, the preparation process of the material is simple and practical and the material has wide range of applications.
