Interface modification method of SiCf/SiC composite material
The invention discloses an interface modification method of a SiCf/SiC composite material. The method comprises the following steps: 1, producing an interface coating layer on the SiC fiber surface of a SiC fiber preform; and 2, processing by adopting a hot die pressing assisted cross-linking PIP technology with the SiC fiber preform with the interface coating layer as a reinforcement and LPVCS as a precursor to produce an interface modified SiCf/SiC composite material. The interface modification method substantially improves the interface combination of fibers and a substrate in the composite material, improves the bending strength and the fracture toughness of the composite material, reduces the porosity of the material and shortens the preparation cycle of the composite material.
