Zusammenfassung:	The invention discloses a water-repellent and warm-keeping fiber aerogel composite material and a preparation method thereof in the technical field of aerogel. The water-repellent and warm-keeping fiber aerogel composite material comprises the following components in parts by weight: 13-18 parts of water-repellent and warm-keeping aerogel and 53-76 parts of a multi-layer hydrophobic fiber net, the water-repellent heat preservation aerogel is a polyvinyl alcohol-polyhedral oligomeric silsesquioxane aerogel prepared from polyvinyl alcohol and vinyl trimethoxy silane; the multi-layer hydrophobic fiber net is prepared from hollow high and low temperature melting fibers with skin-core structures and superfine polyester fibers. According to the invention, through a mode of preparing the hollow skin-core type double-component high-low temperature melting fiber, the loading capacity of aerogel particles is improved, air is fixed by aerogel and hollow fiber, and the technical effect of enhancing the thermal insulation
