The present invention relates to a continuous fiber-reinforced zirconium carbide based composite material and a preparation method thereof, and belongs to the technical field of high temperature thermal protection materials. According to the present invention, the prepared continuous fiber-reinforced zirconium carbide based composite material has excellent performances of lightweight, high performance resistance, anti-oxidation property and the like, the density is 1.9-2.2 g/cm<3>, the tensile strength is 96-150 MPa, the bending/compressive strength is 130-180 MPa, the mass loss under the 2000 DEG C aerobic environment only is 10<-4> g/cm<2>s magnitude, and the composite material shows the good comprehensive performance advantages, and can be applied in novel high hypersonic aircrafts, high-speed re-entry vehicles, reusable orbital maneuvering aircrafts, advanced power systems, and other high temperature thermal protection systems. |
