Abstract
Disclosed is a coated ceramic fiber including a zirconium interface coating layer deposited on the ceramic fiber, a zirconium dioxide interface coating layer adjacent to the zirconium interface coating layer, and an additional interface coating layer adjacent to the zirconium dioxide interface coating layer, wherein zirconium dioxide interface coating layer forms micro cracks after a crystal structure transformation. The coated ceramic fiber may be included in a composite material having a ceramic matrix.
