The invention discloses a manufacturing method for a carbon fiber spoke and the carbon fiber spoke, the manufacturing method comprises the following steps: 1) rolling a carbon sand piece into a bar, and at least separately filling a foaming agent inside the two ends of the bar; 2) nesting one end of the bar into a tooth cap which can be connected to a rim in a matched mode, nesting the other end of the bar into a cap head which can be connected to a flower drum in the matched mode, and separately arranging concave and convex structures on the inner wall surface of the tooth cap and the inner wall surface of the cap head; and 3) curing the bar to form a carbon fiber spoke bar, and separately enabling the outer wall surfaces of the two ends of the carbon fiber spoke bar to form an engaged state with the inner wall surface of the tooth cap and the inner wall surface of the cap head. According to the manufacturing method disclosed by the invention, the carbon sand piece is rolled into thebar and the engaged state is formed after the foaming agent is separately filled into the two ends of the bar and the bar is fixed to the tooth cap and the cap head by curing, and thus, the process issimple, and tensile strength of the carbon fiber spoke is further greatly improved.

    本发明公开了一种碳纤维辐条的制作方法及碳纤维辐条,所述制作方法包括以下步骤:1)将碳砂片卷成棒条,并至少在其两端内部分别装入发泡剂;2)将棒条的一端套入能配合连接车圈的牙帽内,将棒条的另一端套入能配合连接花鼓的帽头内,牙帽的内壁面和帽头的内壁面分别设有凹凸结构;3)对棒条进行固化处理,使之形成碳纤维辐条棒,该碳纤维辐条棒的两端外壁面分别与牙帽和帽头的内壁面形成啮合状态。本发明将碳砂片卷成棒条,并至少在其两端内部分别装入发泡剂后,通过固化与牙帽、帽头固定,同时形成啮合状态,不仅工艺简单,还大大提高了碳纤维辐条的抗拉能力。
