The invention relates to a natural fiber composite bicycle component. A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim. The rim also includes a first sidewall, a second sidewall spaced apart from the first sidewall, and a radially outer tire engaging portion disposed along an outer circumference of the rim. The first sidewall, the second sidewall, the radially outer tire engaging portion, the radially inner portion, or any combination thereof includes a composite laminate. The composite laminate includes a composite material layer. The composite material includes a matrix of a polymer-based material and natural fibers that reinforce the material. The volume of the respective one of the natural fibers of the composite layer prior to lamination of the composite laminate is greater than the volume of the respective one of the natural fibers after lamination of the composite laminate.
本发明涉及天然纤维复合材料自行车部件。用于自行车车轮的轮辋包括沿轮辋的内圆周布置的径向内部部分。轮辋还包括第一侧壁、与第一侧壁间隔开的第二侧壁以及沿轮辋的外圆周布置的径向外部轮胎接合部分。第一侧壁、第二侧壁、径向外部轮胎接合部分、径向内部部分或其任意组合包括复合层压体。该复合层压体包括复合材料层。该复合材料包括聚合物基材料的基质和增强材料的天然纤维。复合材料层的相应一种天然纤维的体积在复合层压体层压之前比复合层压体层压之后的相应一种天然纤维的体积大。
