    • This invention relates to a manufacturing method and structure of a carbon fiber rim. A metal strip is formed by heating a metal substrate to a moldable temperature and then extruded molding. The metal strip comprises two side walls (1), a connecting wall (2) connecting opposite teuminal surfaces of the side walls (1), an inner rim wall (3) connecting the radial inner edges of the side walls (1) to form a space surrounded by the side walls (1), the connecting wall (2), and the inner rim wall (3). Next, two terminals of the strip are connected to form a circle as a rim frame's embryo. The two side walls (1), or the two side walls (1) and the inner rim wall (3) of the rim frame's embryo are milled to form plural through holes (4) and become a rim frame (10). Afterwards, the surface of the rim frame (10) is roughened and covered with a trimmed carbon fiber cloth (20) having a predetermined shape. After heatsetting and surface treating, a carbon fiber rim having a light weight and a strong structure is obtained.
    • 本发明涉及碳纤维轮辋的制造方法和结构。 通过将金属基材加热至可模制温度然后挤出成型形成金属条。 金属带包括两个侧壁(1),连接侧壁(1)的相对的尖端表面的连接壁(2),连接侧壁(1)的径向内边缘的内缘壁(3),以形成 由侧壁(1),连接壁(2)和内缘壁(3)围绕的空间。 接下来,条带的两个端子连接以形成作为轮缘框架的胚胎的圆形。 研磨边缘框架胚胎的两个侧壁(1)或两个侧壁(1)和内边缘壁(3)以形成多个通孔(4)并成为轮辋框架(10)。 之后,将轮辋框架(10)的表面粗糙化并用具有预定形状的修剪后的碳纤维布(20)覆盖。 在热固化和表面处理之后,获得具有轻质量和强结构的碳纤维边缘。

    • The bicycle wheel 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.
    • 本发明的自行车车轮由复合材料制成,并且具有两个相对的制动表面,每个制动表面涂覆有氟化物聚合物层。 具体地说,对制动表面进行喷砂以除去涂在轮上的脱模剂层。 然后将轮子放置在约100摄氏度的喷涂机中,然后用选自聚四氟乙烯,氟化乙烯 - 丙烯共聚物,多氟烷基,乙烯 - 四氟乙烯共聚物的材料对制动表面进行喷涂 并且其混合物直到材料的厚度大于0.4cm。 此后,轮逐渐加热以使材料固化并形成氟化物聚合物层。
