Preparation method of micro-nanofiber/ceramic matrix composite
The invention discloses a preparation method of micro-nanofiber/ceramic matrix composite. The preparation method comprises the following steps: micro-nanofiber is prepared into an aerogel preform and the preform adopts special microstructures of two-dimensional and three-dimensional micro-nanofiber frameworks, high specific surface area, micro-nano level holes, low density, good dispersity of micro-nanofiber, and the like; on the basis, a pyrolytic carbon interface layer is deposited on the preform by using chemical vapour infiltration (CVI); in the end, a ceramic matrix is deposited to be densified to finish the preparation of the micro-nanofiber/ceramic matrix composite. The micro-nanofiber introduced in the method is good in dispersity and wide in the adjustable range of volume fraction, can fully exert the functions of crack deflection, extraction and bridging of micro-nanofiber and can effectively improve the mechanical property of the composite.
