Abstract
The bicycle wheel manufactured by the method of the present invention is made of composite material and has two opposite braking surfaces, each of which is coated with a fluoride polymer layer. Specifically, the braking surfaces are sand blasted to remove a releasing agent layer coated on the wheel. The wheel is, thereafter, placed in a spraying machine at about 100 degree Celsius and then the braking surfaces are spray-coated with a material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, polyfluoroalkyl, ethylene-tetrafluoro ethylene copolymer and the mixture thereof until a thickness of the material is bigger than 0.4 cm. Thereafter, the wheel is gradually heated to make the material set and form the fluoride polymer layers.
