Title:
CERAMIC CONTINUOUS FIBERS HAVING METAL ELEMENT AND CERAMIC MATRIX COMPOSITE MATERIAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/071218
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: ceramic continuous fibers that have a metal element and that are suitable for producing a CMC having high heat resistance; and a CMC using the same. The continuous fibers are characterized by having a metal element having a mass concentration of 10-1000 ppm in the ceramic continuous fibers.
