Disclosed are a composite rim of a vehicle wheel and a method of manufacturing the same, which is reduced in weight through the use of a continuous fiber composite. The rim of a vehicle wheel may be formed by stacking composite sheets, each prepared by impregnating fibers with a resin to form a sheet. The composite sheets may be stacked in multiple layers such that end portions of the respective composite sheets may contact each other in a circumferential direction of the wheel, and discontinuous interfaces, formed at the contacting end portions of the respective composite sheets along an axial direction of the wheel, may not be aligned with each other.

A center pillar for a vehicle is provided and includes carbon-fiber-reinforced plastic (CFRP) and glass-fiber-reinforced plastic (GFRP) that are alternately laminated to reduce the weight of the center pillar and maintain the strength of the center pillar. The center pillar includes a base layer that is formed of CFRP; and laminate layers in which a plurality of layers of CFRP and a plurality of layers of GFRP are alternately disposed on a first surface and a second surface of the base layer individually. Accordingly, the CFRP and the GFRP laminated on the first surface of the base layer and the CFRP and the GFRP laminated on the second surface of the base layer are symmetrical to each other with respect to a thickness direction of the center pillar.

Center pillar for vehicle

A lower stiffener is provided for a bumper of a vehicle. The lower stiffener is mounted on a lower portion of a bumper beam or a front end module (FEM) carrier of the vehicle. The lower stiffener includes a pair of core portions formed by extending in a width direction of the vehicle in an elongated loop shape corresponding to a shape of the bumper of the vehicle, and arranged parallel to each other at a regular interval. A pair of molding portions surrounds the core portions, respectively and a connection portion connects and integrates the pair of molding portions with each other.
