The invention discloses a composite material for an aircraft stringer, and relates to the technical field of aircraft stringer preparation, the composite material comprises: a first support assembly for assembling parts used by the aircraft stringer; the second supporting assembly is located on one side of the first supporting assembly and detachably connected with the first supporting assembly. The butt joint structure has the beneficial effects that the clamping grooves in the first stringer are aligned with the clamping blocks on the second stringer, then the second stringer is moved towards one end of the first stringer, the clamping blocks on the second stringer can extend into the clamping grooves in the first stringer, and therefore butt joint connection between the first stringer and the second stringer can be achieved; meanwhile, the first inserting holes formed in the end faces of the first stringers and the second inserting holes formed in the end faces of the second stringers can be directly used for inserting reinforcing steel bars in a penetrating mode and used for reinforcing and connecting the multiple sets of first stringers and second stringers in a butt joint mode, and therefore the contact area of the contact faces of the first stringers and the second stringers can be increased, friction resistance is increased, and meanwhile firmness is higher.

    本发明公开了一种用于飞机长桁的复合材料,涉及飞机长桁制备技术领域,包括:第一支撑组件,用于组装飞机长桁使用的零部件;第二支撑组件,位于第一支撑组件的一侧且与第一支撑组件可拆卸连接。本发明的有益效果是:使第一长桁上的卡槽与第二长桁上的卡块对齐,然后向第一长桁的一端移动第二长桁,即可使第二长桁上的卡块延伸至第一长桁上的卡槽的内部,从而即可实现第一长桁与第二长桁之间的对接连接,同时第一长桁端面设置的第一插孔和第二长桁端面设置的第二插孔,可直接用于穿插加固钢筋,用于加固并对接多组第一长桁与第二长桁,从而即可延长第一长桁与第二长桁接触面的接触面积,增加了摩擦阻力,同时又使其的牢固性更强。
