Abstract
A rotor for a rotary compressor having a metal central portion integral with two opposite end portions that are fiber-reinforced metal matrix composites having a matrix metal common to the central portion. Such rotors may be made by pressing inorganic fibers to form the end portions of the rotor, arranging the end portions in an opposing relationship in a mold to form the central portion between the end portions. Molten metal is placed into the mold such that it infiltrates the porous end portions while forming the central portion. Solidification of the metal forms fiber-reinforced metal-matrix composite end portions integral with the central portion.
