HIGH STRENGTH CERAMIC FIBER AND METHOD OF MANUFACTURE
PROBLEM TO BE SOLVED: To maximize tenacity of a ceramic matrix composite material.SOLUTION: There is provided a method for forming an interfacial phase in a ceramic matrix composite material having a plurality of SiC fibers. The method includes the steps of: maximizing tenacity by minimizing formation of cross-linking between fibers to align a plurality of SiC fibers in a preform; selectively removing silicon from the surface of the fibers (for example, etching) to provide porous carbon layers on the fibers; and replacing the porous carbon layers with interfacial phase layers (for example, boron nitride). The interfacial phase layer coats the fibers, thereby minimizing formation of cross-linking between fibers in the preform.SELECTED DRAWING: None
【課題】セラミックマトリックス複合材料の靱性最大化。【解決手段】複数のＳｉＣ繊維を有するセラミックマトリックス複合材料中に界面相を形成する方法であって、繊維間の架橋形成を最小化することにより靱性を最大化し、プリフォーム中に複数のＳｉＣ繊維を配列する工程と、繊維の表面からケイ素を選択的に除去（例えば、エッチング）し、繊維上に多孔質炭素層をもたらす工程と、界面相層（例えば、窒化ホウ素）によって多孔質炭素層を置きかえる工程と、を含み、前記界面層相は繊維をコーティングして、それによりプリフォーム中での繊維間の架橋形成を最小化する方法。【選択図】なし
