Abstract
In the embodiments described in the specification, an impeller is manufactured by providing a mold for one angular segment containing one vane of an impeller and corresponding hub and rim portions, injection-molding fiber-reinforced polymer composite resin material into the mold to produce a plurality of substantially identical segments, and assembling the segments into an impeller by bonding corresponding mating end surfaces of the hub and rim portions of the segments. A veil cloth is applied to the outer surface of the rim portion and impregnated with resin material to complete the impeller structure.
