    摘要: Carbon fiber bicycle wheels are formed from parts cut from carbon fiber cloth and then joined together to form a rim, sidewalls, spokes, flanges and a center tunnel on which the flanges are mounted. The parts are then assembled, bonded together, and cured to form a wheel. During assembly, the spokes and the wheel are placed in tension by moving the flanges outwardly on the center tunnel after assembly and then bonding them in place to stiffen and strengthen the wheel. The spokes of the drive side of the rear wheel are specially shaped to accommodate torque transfer forces generated by pedaling.

    摘要: The present invention applies to a molding method for a fiber-reinforced plastic structure having an internal cavity, in particular, for example, a vehicle wheel (10) made from fiber-reinforced plastic. Firstly, grain groups (6a), which mainly consist of a plurality of high-rigidity grains, are accommodated in bags (6), and a plurality of cores (4a-4h) are formed. A reinforcing fiber substrate, such as a prepreg or textile, is placed between the plurality of adjacent cores so as to be interposed therebetween. For example, a plurality of molding base materials are prepared by surrounding each core (4a-4h) with a prepreg (3), and the plurality of molding base materials are combined and placed inside a molding die, and the molding base materials are compression molded. When compression molding, a part of the outer surface of the cores (4a-4h) is locally pressurized, and the internal pressure of the cores is increased, changing the shape thereof, thus eliminating voids that are present between the cores and the prepreg and/or the prepreg and the molding surface of the die.
