The invention discloses a method for manufacturing a wing rib by using a three-dimensional woven composite material and the wing rib, and relates to the technical field of wings, the method comprises the following steps: S1, determining the form of an integrally woven three-dimensional woven preform according to the geometrical shape of the wing rib to be manufactured; s2, determining a tissue form and basic weaving parameters of a three-dimensional woven fabric of the preform according to the geometric dimension of the wing rib; s3, weaving a prefabricated body; s4, preparing a forming mold; and molding in a molding cavity through a vacuum-assisted resin transfer molding process to obtain the wing rib. According to the wing rib woven through the method, due to the strengthening effect generated by interweaving of the yarn in the three-dimensional woven fabric, the layering resistance of the wing rib is improved when the wing rib bears complex loads, and the bearing capacity of a web flange connecting area is also improved.

    本发明公开了一种使用三维机织复合材料制造翼肋的方法及翼肋,涉及机翼技术领域,方法:S1、根据需要制造的翼肋的几何形状确定整体织造的三维机织预制体的形态;S2、根据翼肋的几何尺寸确定预制体的三维机织织物的组织形式和基础织造参数;S3、织造预制体;S4、准备成型模具;通过真空辅助树脂传递模塑工艺在成型腔成型,获得翼肋。使用上述方法织造的翼肋,由于三维机织织物中纱线相互交织产生的强化作用,翼肋在承受复杂载荷时的抗分层性能获得提高,腹板凸缘连接区域的承载能力也获得提高。
