US 2022/0314688 A1 · COMPOSITE RIM OF VEHICLE WHEEL AND METHOD OF MANUFACTURING THE SAME

Abstract

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 method of manufacturing a rim of a vehicle wheel, the method comprising:

preparing a mold corresponding to a shape of the rim;
preparing a plurality of fabric sheets;
stacking the respective fabric sheets in multiple layers on the prepared molds such that end portions of the respective fabric sheets contact each other in a circumferential direction of the mold, discontinuous interfaces of the respective fiber fabric sheets are formed at the contacting end portions of the respective fabric sheets and along an axial direction of the mold,
wherein the discontinuous interfaces of the respective fiber fabric sheets are not aligned with each other;
and
injecting and curing a resin into the stacked fiber fabric sheets.
