Continuous silicon carbide fiber reinforced mullite-based composite material containing interface layer and preparation method of continuous silicon carbide fiber reinforced mullite-based composite material
The invention relates to the technical field of composite materials, in particular to a continuous silicon carbide fiber reinforced mullite-based composite material containing an interface layer and a preparation method of the continuous silicon carbide fiber reinforced mullite-based composite material. Comprising a continuous silicon carbide fiber reinforcement, an interface layer and a matrix, the continuous silicon carbide fiber reinforcement is 2D continuous silicon carbide fiber, 2.5 D continuous silicon carbide fiber or 3D continuous silicon carbide fiber; the matrix is a mullite matrix, a mullite-aluminum oxide matrix or a mullite-silicon dioxide matrix; the interface layer is a zirconium oxide interface layer, an aluminum oxide interface layer, a silicon oxide interface layer, a magnesium oxide interface layer, a mullite interface layer or a composite interface layer formed by the two interface layers; according to the invention, a weak bonding interface is formed between the continuous silicon carbide fiber and a mullite matrix by adopting a sol-gel method, so that the limit energy of fiber pullout and debonding is improved, and the strength of the composite material is improved, thereby obtaining the continuous silicon carbide fiber reinforced mullite-based composite material with high strength, high toughness, high temperature resistance and long service life.
