| titleOfInvention | A kind of high toughness C/ultra-high temperature ceramic composite material and preparation method thereof |
| abstract | The invention relates to a preparation method of a high-toughness C/ultra-high temperature ceramic composite material. The preparation method comprises the following steps: (1) providing a carbon/carbon matrix; (2) under vacuum conditions, mixing expanded boron nitride with The hafnium-tantalum precursor solution is ultrasonically mixed to form an expanded boron nitride-modified hafnium-tantalum precursor solution; (3) using the boron nitride-modified hafnium-tantalum precursor solution as a reactant, through the dip cracking method and the steps (1) The prepared carbon/carbon matrix reacts to form an expanded boron nitride toughened C/C composite material; (4) step (3) is repeated at least once to obtain a boron nitride toughened C/ultra-high temperature ceramic matrix composite material. The preparation method used in the invention further improves the matrix toughness of the C/ultra-high temperature ceramic matrix composite material, thereby effectively solving the problem that the matrix of the C/ultra-high temperature ceramic matrix composite material has many cracks and causes poor mechanical properties. |
