Preparation method of alumina fiber reinforced ceramic composite material
The invention discloses a preparation method of an aluminum oxide fiber reinforced ceramic composite material, and relates to the technical field of aluminum oxide fiber reinforced ceramic composite materials. The preparation method comprises the following steps of: performing ball-milling to prepare aluminum oxide slurry: mixing aluminum oxide nano powder and water, and performing ball-milling toobtain the aluminum oxide slurry; pretreating aluminum oxide fibers or cloth layer: additionally taking the aluminum oxide fibers, soaking the aluminum oxide fibers into a solvent, heating to 70-90 DEG C, then taking out the aluminum oxide fibers, and drying the aluminum oxide fibers at room temperature to obtain solvent-removed continuous aluminum oxide fibers; dipping the continuous alumina fibers in the alumina slurry, winding the continuous alumina fibers on a core mold, performing drying and demolding, and carrying out 900-1200 DEG C heat treatment to obtain the alumina fiber reinforcedceramic composite material. According to the preparation method of the invention, an alumina fiber preform weaving process is omitted, the alumina fibers are used as a reinforcing phase to enhance thestrength of an alumina matrix, and the tensile strength and porosity of the composite material are improved.
