At present, silicon carbide fiber reinforced ceramic matrix composite materials are widely applied to the fields of high-temperature structural materials, high-temperature wave absorbing materials and nuclear reactors.
Silicon carbide (SiC) fiber is a ceramic fiber in which equal amounts of carbon and silicon are periodically arranged in a diamond structure, and the actual silicon carbide fiber may contain carbon and oxygen elements, etc. The silicon carbide fiber has the advantages of small diameter, high strength, high modulus, good temperature resistance, small density, stable chemical property and the like. The high-performance continuous silicon carbide fiber can meet the severe requirements of the high-performance ceramic matrix composite material: fine diameter, oxidation resistance, high temperature resistance, creep resistance and corrosion resistance; can be stably used in the air with the temperature of not lower than 1300 ℃ and in the inert atmosphere with the temperature of not lower than 1600 ℃; the strength of the fiber can reach 1960-4410 MPa, and the modulus can reach 176-400 GPa.
The continuous silicon carbide fiber reinforced ceramic matrix composite is formed by compounding high-strength silicon carbide fibers and a ceramic matrix. The reinforced fiber is equivalent to the framework of the ceramic matrix composite material and is the main component of the composite materialThe macroscopic strength of the composite material to carry the structural units is largely dependent on the strength of the reinforcing fibers. At present, the silicon carbide ceramic matrix composite material is usually made of reinforced fibers such as carbon fibers, silicon carbide fibers, glass fibers and the like. At present, silicon carbide fiber reinforced silicon carbide based composite materials are widely applied to the fields of high-temperature structural materials, high-temperature wave absorbing materials and nuclear reactors, and silicon carbide is used as a matrix material of a ceramic carbide based composite material, so that the silicon carbide fiber reinforced silicon carbide based composite material has the advantages of high melting point, high strength, high modulus and the like. However, silicon carbide ceramic substrates have some disadvantages, such as expensive Polycarbosilane (PCS) as a precursor for preparing the silicon carbide substrate and toxic xylene (xylene), which can cause environmental pollution; the polycarbosilane generates a large amount of gas in the high-temperature cracking process, so that the finally obtained composite material has more pores and is not compact; siC (SiC) f The dielectric constant of the SiC composite material is larger, and the wave absorbing performance can be affected to a certain extent.
