ABSTRACT:
An article of manufacture illustrated in the form of an impeller having a rotor extending in radial directions from a central axis to an outer periphery and a plurality of vanes unitary with the rotor and extending from the rotor in axial directions essentially parallel to the central axis, each vane having a length along an axial direction, is constructed of a structural composite including a plurality of layers of reinforcing fibers in a matrix of synthetic polymeric material, each layer extending essentially parallel to the radial directions, the layers being juxtaposed with one another along the axial direction, the reinforcing fibers of each layer being woven in a pattern essentially perpendicular to the central axis, and further reinforcing fibers extending in the axial directions and stitched through the juxtaposed layers, the further reinforcing fibers extending within each vane, along the length of each vane, essentially parallel to the length of the vanes.
