Abstract
Continuous fiber reinforced metal matrix composites (MMCs) have been researched and developed because of both high specific strength and high temperature capability and various trial high temperature structural components have been successfully fabricated in the field of aeronautics, aerospace and power generation industries. However, there is the limited number of research for long-term durability performance at practical use temperature ranges in comparison with the static strength characteristics. The final goal of this research is to establish the fatigue damage tolerance design concepts for continuous fiber partially reinforced Ti-alloy matrix composite (TMCs) rotating parts in aircraft engines. This paper summarizes the elevated temperature low cycle fatigue behavior for Ti-alloy matrix composites.
