Recently inverter speed control for room air conditioners has been expanding to control room temperature precisely and to save energy. Therefore high efficiency and high reliability of compressors under wide range from low speed to high speed operation are required. To achieve these requirements improvement of mechanical design and adoption of a reliable light weight material for the moving parts have been researched. In this paper we discuss the research progress of Metal Matrix Composite (MMC) as a high strength, reliable light weight material and the results of the development of Fiber Reinforced Aluminum Alloy (FR-Al) for the moving parts. And we also discuss mechanical and physical properties of the FR-Al, merit of using the FR-Al in rotary compressors as the roller and the vane, and tribological and reliability evaluation of the FR-Al applied in Hydrofluorocarbon (HFC) refrigerant and polyolester lubricant atmosphere.
