Porous silicon carbide preform with controllable porosity and preparation method thereof
The invention belongs to the field of composite material preparation, and particularly relates to a porous silicon carbide preform with controllable porosity and a preparation method thereof.The porous silicon carbide preform is formed by mixing and compounding three kinds of silicon carbide powder with different particle sizes, the silicon carbide powder is prepared from, by mass, 50%-60% of silicon carbide coarse powder with the particle size being 100-120 microns, 30%-40% of silicon carbide fine powder with the particle size being 30-40 microns and 10%-15% of silicon carbide micro powder with the particle size being 6-8 microns, and mixing, primary ball milling, drying, secondary mixed ball milling, degassing, molding, heating elimination, sintering molding, detection and permeation filling are conducted. And finally, the aluminum silicon carbide composite material is obtained, so that the quality of the manufactured aluminum silicon carbide composite material is ensured, and the porosity and aperture quality of the produced aluminum silicon carbide composite material are ensured.
