Abstract
A method of fabricating a damage tolerant shaft is provided in which a plurality of lobes are initially formed and are then positioned relative to one another to define an annular body and a plurality of ribs extending within the annular body. The plurality of lobes are formed of a plurality of reinforcing fibers extending at least partially about a respective lobe. Once the lobes have been positioned relative to one another, interstices between portions of adjacent lobes may be filled. Additionally, the plurality of lobes may be surrounded by an outer layer, also formed of reinforcing fibers extending at least partially about the plurality of lobes. The plurality of lobes may be impregnated with resin and cured, either prior to being positioned relative to one another or thereafter.
