Research

Our laboratory focuses on the materials used in a space vehicle (rocket, spaceplane, satellite, planet explorer). Those materials are required to improve their mechanical properties and reliability in extraordinary environments (ultra-high or cryogenic temperature, hypervelocity impact, etc.). At present, the following themes closely relating to ISAS/JAXA’s space science missionss are studied:
(1) Creep-Fatigue of Cu alloys for rocket engine combustion chamber.
(2) Development of high/low-temperature shape-memory alloys and their space applications.
(3) Ceramics/metal dissimilar-material brazing
(4) Deterioration and damage evaluation in SiC/SiC composite.
(5) Nondestructive reliability evaluation.
