Abstract:
Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.
