The invention discloses a high-heat-insulation impact-resistant weaving material as well as a preparation method and application thereof. The weaving material is composed of Al2O3-YTaO4 ceramic fibers, polyimide fibers and nickel-based high-temperature alloy filaments according to the mass ratio of (55-60): (10-15): (20-25). The molar ratio of Al2O3 to YTaO4 in the Al2O3-YTaO4 ceramic fiber is (1 to 2): (8 to 9). According to the preparation method, Al2O3-YTaO4 fibers, polyimide fibers and nickel-based high-temperature alloy filaments are subjected to blended spinning to obtain the high-heat-insulation and impact-resistant weaving material. The high-heat-insulation and impact-resistant woven material is applied to preparation of a tire protective cover for a missile launching vehicle, and specifically, the high-heat-insulation and impact-resistant woven material is prepared into a woven body in the shape of a tire of the missile launching vehicle. The weaving material provided by the invention has excellent tensile strength and impact resistance, and can be applied to preparation of a protective cover of a missile launching vehicle tire. In addition, the weaving material is simple in preparation process, and has the advantages of being foldable and convenient to carry due to the addition of the ceramic fibers.
