    • A barrel assembly for a composite structure includes a barrel (100) of composite material, a first end ring (120), and a mid support (140). The barrel of composite material has a first end, an interior surface and an outer surface, and the first end ring is removably attached to the first end. The first end ring has a perimeter that is substantially congruent with the first end, and is configured to maintain a shape of the barrel. The mid support is removably disposed within the barrel, and has a plurality of spokes (144) extending outwardly from a central hub (146) to contact the interior surface, to maintain a shape of the barrel. An edge stabilizer for the composite structure includes an elongate edge support segment (1500), defining a geometric shape of an edge of the composite structure, and a connector (1518), configured to attach the edge support segment to the edge of the composite structure. The system can also include a moveable cart (700), the barrel section being supportable upon the cart.
    • 用于复合结构的桶组件包括复合材料的桶(100),第一端环(120)和中间支撑件(140)。 所述复合材料桶具有第一端,内表面和外表面,并且所述第一端环可移除地附接到所述第一端。 第一端环具有与第一端基本一致的周边,并且构造成保持筒的形状。 中间支撑件可移除地设置在筒内,并且具有从中心毂(146)向外延伸以接触内表面的多个辐条(144),以保持筒的形状。 用于复合结构的边缘稳定器包括限定复合结构边缘的几何形状的细长边缘支撑段(1500),以及连接器(1518),其构造成将边缘支撑段附接到复合结构的边缘 。 该系统还可以包括可移动推车(700),所述桶部分可在所述推车上支撑。

    • A vacuum bag (18) is placed around the inner forming surface (IML) of an inner mandrel with radially retractable sectors (11a, 11b) having parallel longitudinal slots (17). Stringers (30) of composite material are positioned in the slots (17). A respective elongated inner support (31) is placed in each stringer, covered by an impermeable tubular bag (32). A skin (37) of composite material is laminated around the stringers (30), the coated supports (31, 32) and the inner forming surface (IML). An outer curing tool (50, 51) closes around the skin (37) defining an outer forming surface (OML) for the fuselage barrel, leaving an annular gap (G) of predetermined radial width between the outer surface of the skin (37) and the outer forming surface (OML). Vacuum is applied to the volume enclosed between the vacuum bag (18) and the outer tool (50, 51), so as to enlarge the diameter of the uncured barrel, causing the barrel to be released from the inner mandrel (10) and bringing the outer surface of the skin (37) into contact with the inner surface (OML) of the outer tool (50, 51).
    • 真空袋(18)围绕具有具有平行的纵向狭槽(17)的径向可缩回的扇形部分(11a,11b)的内部心轴的内部成形表面(IML)放置。 复合材料的纵梁(30)定位在槽(17)中。 相应的细长的内部支撑件(31)放置在每个纵梁中,由不透水的管状袋(32)覆盖。 复合材料的皮肤(37)层叠在桁条(30),涂覆支撑件(31,32)和内部成形表面(IML)周围。 外固化工具(50,51)围绕限定用于机身筒的外部成形表面(OML)的皮肤(37)闭合,在皮肤(37)的外表面之间留下预定径向宽度的环形间隙(G) 和外部成形表面(OML)。 真空被施加到真空袋(18)和外部工具(50,51)之间的体积上,以便增大未固化桶的直径,从而使桶从内部心轴(10)中释放并带来 皮肤(37)的外表面与外部工具(50,51)的内表面(OML)接触。
