Preparation method of continuous oxide fiber reinforced oxide ceramic based composite
The invention belongs to the preparation technology of a continuous fiber reinforced ceramic based composite, and relates to a preparation method of a continuous oxide fiber reinforced oxide ceramic based composite. The technology comprises the steps that an organic ceramic precursor solution is utilized to serve as solvent to prepare slurry with ceramic powder, the slurry is smeared on the surface of oxide fiber fabric to prepare oxide fiber prepreg, the technological processes of laminating, mold pressing and sintering are conducted on the prepreg, a low-porosity ceramic based composite preform is obtained, the repeated processes of soaking and splitting are conducted by adopting an organic ceramic precursor, and the continuous fiber reinforced ceramic based composite with the ideal density is obtained. According to the preparation method of the continuous oxide fiber reinforced oxide ceramic based composite, the organic ceramic precursor is adopted to serve as the solvent to prepare the ceramic slurry, the organic ceramic precursor can play a role of bonder for bonding the ceramic powder, low-temperature inorganic characteristics of the organic ceramic precursor can be utilized, fiber is protected against thermal damage caused by high temperature in the composite preparation process, and the composite strength is improved.
