Ceramic Matrix Composites Group

Outline of Group

Ceramic matrix composites (CMCs) are damage-tolerant materials avoiding unexpected catastrophic fracture though the use of their composite structure.  They have recently been used in the hot sections of civil jet engines due to their low density and excellent mechanical properties at high temperature; their application fields are expected to be expanded to other sections in jet engines and nuclear power plants.
We conduct fundamental researches and developments of CMCs and their environmental barrier coatings (EBCs), including new effective and low cost processing; evaluation techniques of  mechanical properties and fracture mechanism; evaluation of degradation in a variety of environments.

Research Themes

  1. High- sinterability SiC nano-power processing
  2. New SiC/SiC processing utilizing greensheets and prepreg sheets
  3. Evaluation techniques for interface toughness of EBCs
  4. In-situ microscopic observation and strain distribution measurement over 1400℃
