The invention discloses a carbon fiber bicycle rim and a preparation method thereof.The carbon fiber bicycle rim comprises an annular rim body, the rim body is integrally formed by carbon fibers, the rim body comprises an outer ring wall, an inner ring wall and two side walls connecting the outer ring wall and the inner ring wall, a semi-closed tire groove is formed in the outer side of the outer ring wall, and the tire groove is formed in the outer side of the inner ring wall. A closed cavity is defined by the inner side of the outer ring wall, the inner ring wall and the side wall, a connecting part is arranged in the cavity, one end of the connecting part is connected with the outer ring wall, the other end of the connecting part is connected with the side wall, and a hollow channel is defined by the connecting part, the outer ring wall and the side wall. According to the carbon fiber bicycle rim and the preparation method thereof, the connecting parts are arranged to form the hollow channel between the outer ring wall and the side wall of the carbon fiber bicycle rim, the weight of carbon fibers is basically unchanged, but the strength and the impact resistance of the carbon fibers are effectively improved, the relation between the weight and the strength of the carbon fiber bicycle rim is well balanced, and the service life of the carbon fiber bicycle rim is prolonged. And the overall performance of the rim is effectively improved.

    本发明公开了一种碳纤维自行车轮圈及其制备方法,碳纤维自行车轮圈包括呈环状的轮圈本体,所述轮圈本体由碳纤维一体成型,所述轮圈本体包括外环壁、内环壁、连接所述外环壁及内环壁的两侧壁,所述外环壁的外侧形成半封闭的胎槽,所述外环壁的内侧与所述内环壁、侧壁围合形成封闭的腔体,所述腔体内设有连接部,所述连接部一端与所述外环壁连接,另一端与所述侧壁连接,所述连接部与所述外环壁、侧壁围合形成中空通道。本发明碳纤维自行车轮圈及其制备方法,通过设置连接部在碳纤维自行车轮圈外环壁与侧壁之间形成中空通道,碳纤维的重量基本不变,但其强度及抗冲击性能得到有效提升,很好的平衡的碳纤维自行车轮圈重量和强度的关系,使得轮圈的整体性能得到有效提升。
