炭化ケイ素(SiC)複合材料
Purpose of Research
高温エネルギー利用の社会を構築する複合材料の開発炭化ケイ素(SiC)複合材料は,「軽量」かつ「優れた耐熱性」をもち,金属材料では耐えられない高温においても,構造材料として求められる「強度」「耐酸化性」「耐摩耗性」を発揮する。新しく杯初されなNITE SiC/SiC複合材料は大型部材の作製技術,形状自由度の確保,接合技術など様々な要求の全てをクリアできる材料である。金属材料に替わる構造材料として炭化ケイ素(SiC)複合材料を作成する。
Summary of Research
金属の大体になりえるセラミックス複合材料の製造技術を追求セラミックスでる炭化ケイ素(SiC)複合材料は,様々な形状を作るのが難しいとされてきたが,繊維束中にSiCナノパウダーを含浸させて,高温高圧でSiCを結晶成長させ,焼き固める「NITE法」という製法で,形状の多様化を可能にした。高純度・高結晶性のSiC/SiC複合材料を製作している。
