The invention belongs to the related technical field of high-temperature ceramic matrix composite materials, and discloses a preparation method and product of a continuous fiber reinforced ZrC/SiC composite part. The specific steps include: S1 adopting additive manufacturing technology to prepare a continuous fiber reinforced resin preliminary blank; S2 pyrolytic carbonization of the preliminary blank to obtain a carbon preliminary blank; S3, in the prepared carbon preliminary blank, a protective layer is formed on the surface of the carbon fiber to protect the continuous fiber S4 carries out impregnation with the carbon initial blank in the thermosetting phenolic resin solution, solidifies, then pyrolysis carbonization again carries out densification; S5 repeats step S4 repeatedly to obtain final carbon preform, and this carbon preform is carried out Zr-Si reaction Sintering, so that the pyrolytic carbon reacts with Zr-Si to form ZrC-SiC, so as to obtain continuous fiber-reinforced ZrC/SiC composite parts. The invention solves the problems that SiC products are not resistant to high temperature and the distribution of component structures in carbon fiber reinforced ZrC is uneven. |
