High-strength carbon fiber hub and manufacturing process thereof

The invention discloses a high-strength carbon fiber hub and a manufacturing process thereof, and relates to the technical field of hub manufacturing. Polyacrylonitrile fibers are subjected to step-by-step carbonization to obtain high-strength carbon fibers; the step-by-step carbonization comprises pre-oxidation and carbonization which are carried out step by step; the high-strength carbon fibers are subjected to dipping treatment and then subjected to curing forming in the hub mold, and finally the finished hub is obtained through polishing; compared with a traditional aluminum alloy hub, the carbon fiber hub prepared through the method has the advantages of being lighter in mass, higher in strength, capable of avoiding the defect of metal fatigue, capable of obviously reducing noise and the like, and along with continuous development of new energy automobiles, the application space of the carbon fiber hub is wider than that of the traditional aluminum alloy hub, and the market potential is huge. 本发明公开了一种高强度
