Claim:
1. A method of fabricating a damper having a locally coated material, comprising: forming a printed pattern on a screen, the printed pattern having an outer edge and an inner edge, the outer edge of the printed pattern having a circular shape and the inner edge of the printed pattern having a wave shape; providing a fiber fabric having at least a damper forming region, the damper forming region having a predetermined coating region; soaking the fiber fabric in a resin bath so that the fiber fabric contains a resin and has increased hardness; placing the fiber fabric containing the resin below the screen so that the printed pattern is aligned with the predetermined coating region; pouring a coating material on the screen and distributing the coating material over the printed pattern, whereby the coating material flows through a gap region of the printed pattern onto the predetermined coating region, the predetermined coating region thereby having a shape that matches with that of the printed pattern, an outer edge with a circular shape and an inner edge with a wave shape; and after the fiber fabric being applied with the coating material and baked, the fiber fabric undergoing a cutting step so that the damper forming region eventually forms a damper, the shape of the outer edge of the predetermined coating region remains unchanged, and the inner edge of the predetermined coating region is converted from a wave shape to a circular shape, thereby the coating material being regularly and uniformly distributed in annular shapes on the surface of the damper.
