Publication number: 20110163594Abstract: A manufacturing process for a bicycle hub includes steps of preparing dry carbon fiber fabric, covering around inner tube, placing in upper and lower molds, injecting adhesive into the upper and lower molds, and forming by heating and pressurizing. Because the manufacturing process uses tubular dry carbon fiber fabric to form a hub shell, the manufacturing process is simple and the produced hub has few defects. Thus, the production rate and product stability are enhanced.Type: ApplicationFiled: January 5, 2010Publication date: July 7, 2011Inventor: SHU-WEI LIN
