| titleOfInvention | In-situ grown carbon interface layer modified SiC/SiC composite material and preparation method thereof |
| abstract | The invention provides an in-situ grown carbon interface layer modified SiC/SiC composite material and a preparation method thereof, wherein the method comprises the following steps: (1) reacting the SiC fiber preform with a first precursor to obtain a first sample (2) containing a carbon interface layer, carrying out chemical vapor deposition reaction on the first sample and a second precursor to further obtain a second sample (3) containing an SiC interface outer layer, and soaking the second sample in a third precursor to obtain a third sample; (4) carrying out curing and cracking reactions on the third sample in sequence to obtain a fourth sample; (5) and (4) repeating the steps (3) to (4) at least once, and then carrying out liquid silicon infiltration to obtain the modified SiC/SiC composite material. The modified SiC/SiC composite material prepared by the invention has an in-situ grown complete carbon interface layer and excellent mechanical properties. |
