▎ 摘　　要

NOVELTY - Ceramic matrix composite stud comprises fiber preform, interface layer, and ceramic matrix. The density of the fiber preform gradually decreases from the inside to the outside. The interface layer is composite interface layer or gradient interface layer. The composite interface layer is pyrolytic carbon interface layer, boron nitride interface layer, and silicon carbide interface layer. The gradient interface layer is interface layer with a gradient distribution of silicon to carbon ratio. The silicon and carbon ratio gradually increases from the inside to the outside. The ceramic matrix is silicon carbide matrix containing nanofibers. USE - Used as ceramic matrix composite stud. ADVANTAGE - The stud has short preparation period, high strength and excellent mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the ceramic matrix composite stud.
