Preparation method of aluminum-silicon fiber reinforced aluminum-silicon ceramic matrix composite bolt
The invention relates to a preparation method of an aluminum-silicon ceramic matrix composite bolt, and belongs to the field of ceramic matrix composites. According to the method, aluminum-silicon reinforced fibers are filled with ceramic slurry through a layer laying process or a vacuum auxiliary slurry infiltration process, an aluminum-silicon fiber reinforced aluminum-silicon ceramic-based composite material is obtained through primary sintering and densification treatment, and the ceramic-based composite material bolt which is resistant to high temperature, low in heat conductivity and high in strength is finally obtained through machining. The method has the advantages of low raw material cost, short preparation period and good processability of the prepared composite material, the processed aluminum-silicon fiber reinforced aluminum-silicon ceramic-based composite material bolt can be used in an air environment of 1100 DEG C for a long time, the thermal conductivity is as low as 0.5 W/(m.K), and the service life of the bolt is prolonged. And meanwhile, the composite material bolt prepared by adopting the method is excellent in tensile property, shearing resistance and torsion resistance, and has a wide application prospect in the field of ceramic-based thermal protection connecting piece materials.
