Cf/C-(TaNb, Ti, Zr, Hf) C composite material and preparation method thereof

The invention provides a Cf/C-(TaNbTiZrHf) C composite material and a preparation method thereof.The preparation method comprises the following steps that 1, a Ta source, an Nb source, a Ti source, a Zr source and an Hf source are added into ethyl alcohol, and a mixed solution A is prepared; 2) standing the mixed solution A under an ice bath condition, then adding furfuryl alcohol, and uniformly mixing to obtain a mixed solution B; 3) putting the carbon/carbon composite material blank into the mixed solution B for vacuum impregnation, and drying the obtained product to obtain a target product preform; and 4) performing high-temperature carbonization on the target product preform to obtain the Cf/C-(TaNbTiZrHf) C composite material. The preparation method is simple in operation process, five transition metal elements can be introduced into the carbon/carbon composite material by utilizing the spontaneous polycondensation curing characteristic of furfuryl alcohol under a specific temperature condition, and the
