A continuous fiber brake rotor perform, apparatuses and methods for manufacturing the preform are disclosed. The preform comprises a plurality of continuous fiber streams or filaments forming a substantially helical structure having layers or flights compressed together in the preform' s longitudinal direction. Each continuous fiber stream or filament may comprise the same or different types of fiber, extends substantially between longitudinally disposed preform ends, and resides laterally adjacent to another continuous fiber stream o filament within each layer or flight of the helical structure. The radial distance between each continuous fiber stream or filament and the preform' s longitudinal axis varies with angular location about the longitudinal axis. The preform further comprises web or z-direction fiber interspersed within the helical structure with certain of the web or z-direction fibers and continuous fiber streams or filaments extending at partially in the longitudinal direction between the preform' s layers or flights. |
