The invention discloses an unmanned aerial vehicle composite material control surface structure and a processing method thereof, the control surface structure comprises a skin, a core material, a beam, a suspension joint, a suspension and control integrated joint, an end rib, a front edge end partition plate and a tail edge strip, the suspension joint and the suspension and control integrated joint adopt aluminum alloy integral machining parts, the core material adopts a honeycomb core or a closed-cell rigid foam core, the skin adopts composite material carbon fiber fabric or glass fiber fabric prepreg, and the tail edge strip is a composite material glass fiber reinforced plastic U-shaped part. Firstly, a beam, a suspension joint, a suspension control integrated joint and an end rib are riveted into a control surface framework, then a core material is placed in the framework according to the corresponding position and is in glue joint with the framework, gaps are filled with polystyrene foam, then the framework serves as a film pasting tool to be pasted with skin prepreg, after skin pasting is completed, curing forming is conducted according to the model and process specifications, and the control surface is formed. And then cutting and deburring the edge of the control surface of the composite material, and mounting and fixing a tail edge strip at the tail edge by using a rivet.
本发明公开了一种无人机复合材料操纵面结构及其加工方法,操纵面结构含有蒙皮、芯材、梁、悬挂接头、悬挂操纵一体接头、端肋、前缘端隔板和尾边条,梁和端肋采用复合材料碳纤维层压件,悬挂接头和悬挂操纵一体接头采用铝合金整体机加件,芯材采用蜂窝芯或者闭孔刚性泡沫芯,蒙皮采用复合材料碳纤维织物或玻璃纤维织物预浸料,尾边条为复合材料玻璃钢U型件。先将梁、悬挂接头、悬挂操纵一体接头、端肋铆接为操纵面骨架,再将芯材按对应位置放置骨架内,并与骨架胶接,缝隙处填充发泡胶,然后以骨架为贴膜工装铺贴蒙皮预浸料,蒙皮铺贴完成后按型号工艺规范固化成型,之后再对复合材料操纵面边缘切割、修毛刺,尾缘处用铆钉安装固定尾边条。
