Chopped silicon carbide fiber reinforced ZrC multilayer cladding material and preparation method thereof

The invention relates to the technical field of ZrC ceramic materials, in particular to a chopped silicon carbide fiber reinforced ZrC multilayer cladding material and a preparation method thereof. The preparation method of the chopped silicon carbide fiber reinforced ZrC multilayer cladding material comprises the following steps: firstly, with aggregate, chopped SiC fibers, carbon black and thermosetting phenolic resin as raw materials, adding a dispersing agent, and carrying out mixing, injection molding, low-temperature curing and high-temperature biscuiting to obtain a porous carbon-containing preform; with zirconium or zirconium-silicon alloy as an infiltration agent, carrying out high-temperature infiltration sintering on the porous carbon-containing preform to obtain a fiber-toughened ultrahigh-temperature ceramic tube; and finally, carrying out dip-coating in an ethanol solution of a ceramic precursor, and carrying out high-temperature ceramic conversion to obtain the chopped silicon carbide fiber rei
