The invention belongs to the technical field of aircraft structure design, and discloses a composite material integrated frame beam and a manufacturing method, the integrated frame beam is of a cross-shaped structure as a whole, one direction of the cross-shaped structure is the X direction, and the other direction of the cross-shaped structure is the Y direction; the integrated frame beam comprises an upper cross-shaped pavement layer, a middle cross-shaped pavement layer and a lower cross-shaped pavement layer. Wherein the middle cross-shaped paving layer comprises a paving layer with an I-shaped cross section in the X direction and a paving layer with an I-shaped cross section in the Y direction; wherein the paving layer with the I-shaped cross section in the X direction comprises two continuous composite fabrics with C-shaped cross sections, and the paving layer with the I-shaped cross section in the Y direction is a discontinuous composite fabric and comprises a left half paving layer and a right half paving layer; and both the left half part paving layer and the right half part paving layer consist of two continuous composite fabrics with C-shaped sections. And a sewing process is used in the intersection area. According to the integrated frame beam, integrated forming can be achieved, layering can be avoided, and the strength is guaranteed.

    本发明属于飞行器结构设计技术领域,公开了一种复合材料一体化框梁及制造方法,一体化框梁整体为十字型结构,十字型结构的一个方向为X方向,另一个方向为Y方向;所述一体化框梁述包括:上十字铺层、中间十字型铺层、下十字铺层;其中,中间十字型铺层包含X方向截面为工型的铺层和Y方向截面为工型的铺层;X方向截面为工型的铺层包含两个C型截面的连续复材织物,Y方向截面为工型的铺层为不连续复材织物,且包含左半部分铺层和右半部分铺层;左半部分铺层、右半部分铺层均由两个C型截面的连续复材织物组成。在交汇区使用缝纫工艺。该一体化框梁能够实现一体化成型,且能避免分层、保证强度。
