| Outline of Final Research Achievements |
We focused on Ti3SiC2 and Al4SiC4, nanolayered ternary carbides, as candidates as environment-resistant interphases for SiCf/SiC composites. The objectives of this study was to develop the novel environment-resistant interphases for ceramic-based composites by electrophoretic deposition (EPD) method. As a result, we clarified that Ti3SiC2 and Al4SiC4 formed by EPD method are promising as novel interphases with environment resistance for SiCf/SiC composites.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，層状構造を有し，高温下において耐熱性及び耐酸化性に優れるTi3SiC2やAl4SiC4の三元系ナノ層状炭化物を用い，本研究グループが開発した低環境負荷・低コストプロセスであるEPD 法により，SiCf/SiC複合材料の耐環境性に優れる界面層の形成が可能であることを世界に先駆けて明らかにした．本研究は，耐環境性界面層及びその製造プロセスのどちらについてもこれまでに国内外において例のない革新的成果である．
