Abstract: Aircraft electric motors are described. The electric motors include an annular rotor sleeve having an inner wall, a connecting wall, and an outer wall, wherein the inner wall, the connecting wall, and the outer wall define a U-shaped channel configured to receive a U-shaped magnet structure and a sleeve inner cavity defined radially inward from the inner wall, a hub connector extending radially inward from the inner wall into the sleeve inner cavity, a hub arranged in the sleeve inner cavity and fixedly connected to the hub connector, wherein the hub is configured to rotate with rotation of the rotor sleeve, and a U-shaped magnet structure arranged within the U-shaped channel of the rotor sleeve. At least one of the rotor sleeve, the hub connector, and the hub are formed from a composite material.

Abstract: A method of forming a fiber reinforced composite material includes cutting a plurality of reinforcing fibers to a selected length, directing the plurality of reinforcing fibers through a fiber alignment mechanism, orienting the plurality of reinforcing fibers in a selected direction via the fiber alignment mechanism, and adhering the aligned plurality of reinforcing fibers to a substrate material to form the fiber reinforced composite material. A system for manufacturing a fiber reinforced composite material includes a feed mechanism to direct a substrate material along a selected path, a cutting mechanism to cut a plurality of reinforcing fibers to a selected length, and a fiber alignment mechanism to orient the plurality of reinforcing fibers in a selected direction before adhering the plurality of reinforcing fibers to the substrate material.
