The invention discloses an integrated composite cylinder containing internal reinforcing ribs and a preparation method. The integrated composite cylinder comprises annular reinforcing ribs, longitudinal reinforcing ribs and a tubular surface, the tubular face is cylindrical, the longitudinal reinforcing ribs are arranged on the inner side wall of the tubular face in the axial direction of the tubular face, the annular reinforcing ribs are arranged on the longitudinal reinforcing ribs, and the integrated composite tubular barrel with the internal reinforcing ribs is formed. According to the method, the reinforcing rib net rack and the barrel are laid and wound on the same core mold through a laying and winding machine, one-time curing is adopted, the residual stress is reduced due to the fact that the adding force between the reinforcing rib net rack and the barrel is increased, and the mechanical property of a product is better. And by using the rapid tubular winding machine, the manufacturing period can be greatly shortened, and the manufacturing cost is greatly reduced. And the method is particularly suitable for rapidly manufacturing various integrated composite body sections containing internal reinforcing ribs, such as airplanes and cruise missiles.

    一种含有内部加强肋的一体化复材筒体及制备方法,包括环向加强肋、纵向加强肋和管状面;管状面为圆筒状,若干纵向加强肋沿管状面的轴向方向设置在管状面的内侧壁上,若干环向加强肋设置在若干纵向加强肋上,形成含有内部加强肋的一体化复材管状筒体。本发明使用铺缠机在同一个芯模进行加强肋网架和筒体的铺缠并采用一次性固化,使加强肋网架与筒体之间的加合力增加残余应力减小,产品的力学性能更好。使用快速管状铺缠机,能大幅缩短制造周期,使制造成本大幅降低。特别适合飞机、巡航导弹等各种含有内部加强肋的一体化复材身段的快速制造。
