Summary

Ceramic matrix composites (CMCs) exit guide vane (EGV) has been investigated and evaluated in ESPR (Research and Development of Environmentally Compatible Propulsion System for Next-Generation Supersonic Transport) program in Japan. CMCs are attractive materials for hot section parts in jet engine because they are lightweight and have excellent high temperature capabilities. However, the durability of conventional CMCs has not been enough at elevated temperature and the parts life has been limited. the material durability represented by creep rupture property has been modified in this study and the strength was improved 70% at intermediate temperature (1273K), comparing with the CMCs that were developed in previous work. Near net shape process technology is also needed in order to fabricate complex vane shape. Near net manufacturing of CMC vane has been developed and the fabrication technology was evaluated by tensile strength using cut up specimens from the prototype vane. the results of cut up specimens test showed appropriate strength that was estimated from flat plate specimens.
