Abstract:
1. A manufacturing process for a bicycle hub comprising preparing dry carbon fiber fabric: at least one layer of tubular dry carbon fiber fabric being pre-woven and each one of the at least one layer of tubular dry carbon fiber fabric being formed by weaving and covering with at least one layer of carbon fiber; covering around an inner tube: the at least one layer of tubular dry carbon fiber fabric being covered around a metal inner tube and at least one of the at least one layer of tubular dry carbon fiber fabric wrapping multiple reinforcing elements respectively on two ends; placing in upper and lower molds: the inner tube and the at least one layer of tubular dry carbon fiber fabric covered around the inner tube being placed in upper and lower molds; vacuuming: the inside of the upper and lower molds being vacuumed; injecting adhesive into upper and lower molds: adhesive being injected into the upper and lower molds and the at least one layer of tubular dry carbon fiber fabric being fully permeated by and impregnated with adhesive; and forming by heating and pressurizing: the at least one layer of tubular dry carbon fiber fabric impregnated with adhesive being heated and pressurized to form at least one carbon fiber layer.
