The invention discloses a method for repairing a metal honeycomb sandwich structure, which relates to the technical field of aviation maintenance, and is characterized in that a maintenance area is delimited, a belt structure body and semi-solid glue are arranged in the maintenance area, the belt structure body is connected to the top of a dividing wall of a bee chamber, and the semi-solid glue covers the belt structure body and the top of the dividing wall; removing the belt structure body and the semi-solid glue above the belt structure body to form a channel in the residual semi-solid glue at the top of the dividing wall; the semi-solid glue is heated to be solidified, a solid glue layer covering the top of the dividing wall is formed, an air channel is formed in the solid glue layer, and gas generated in the process that the skin is bonded through the glue film can be guided out of the air channel. According to the repairing method, by removing the belt structural body and the semi-solid adhesive located above the belt structural body, the air channel is formed in the solid adhesive layer, water vapor can be discharged out of the repairing area through the air channel, the influence factors of the water vapor in the adhesive film bonding process are eliminated, and the adhesive film bonding quality and the adhesive film bonding effect are ensured.
本发明公开了一种金属蜂窝夹层结构的修复方法,涉及航空维修技术领域,其通过划定维修区域,并在维修区域内设置带结构体和半固态胶,使带结构体连接于蜂室的间壁顶部,半固态胶覆盖带结构体、以及间壁顶部,通过移除带结构体以及位于带结构体上方的半固态胶,使剩余于间壁顶部的半固态胶内形成通道;加热半固态胶,使半固态胶受热凝固,形成覆盖于间壁顶部的固态胶层,固态胶层内形成了气道,使蒙皮通过胶膜粘接的过程中,产生的气体能够从气道导出。本修复方法通过移除带结构体以及位于带结构体上方的半固态胶,使固态胶层内形成有气道,水汽能够通过气道排出维修区域,排除了胶膜粘接过程中水汽的影响因素,确保了胶膜的粘接质量和粘接效果。
