The invention discloses a dehumidification method for a honeycomb sandwich structure, which comprises the following steps of: removing a skin in a damaged area, and selecting a negative pressure joint position and a plurality of pressure relief positions in the damaged area; sequentially laying a separation membrane, collodion absorption cotton, a heating blanket, breathable cotton and a vacuum bag, and heating the damaged area; one pressure relief position is selected as a first hole opening position, a pressure relief hole is formed in the corresponding position of the vacuum bag for pressure relief, the pressure relief hole is blocked after a first preset time so as to complete one-time pressure relief operation, and then the pressure relief operation is repeated in the other pressure relief hole; and after the pressure relief positions are all provided with holes for pressure relief, the preset temperature is maintained for a second preset time, and then cooling treatment is conducted till dehumidification is completed. According to the invention, effective volatilization of moisture is ensured, and the vicinity of a heating dehumidification area is not damaged due to heating degumming.

    本发明公开了一种蜂窝夹芯结构的除湿方法,包括如下步骤:去除损伤区域的蒙皮,并于所述损伤区域选定负压接头位以及多个泄压位;依次铺设分离膜、吸胶棉、加热毯、透气棉以及真空袋,并对所述损伤区域进行加热;选定一所述泄压位作为第一开孔位,于所述真空袋上对应位置开设泄压孔进行泄压,待第一预设时间后封堵所述泄压孔,以完成一次泄压操作,随后于另一所述泄压孔重复所述泄压操作;待所述泄压位均开孔泄压后,维持预设温度第二预设时间,随后进行降温处理直至完成除湿。本发明保证潮气有效挥发的同时,加热除湿区域附近不会因加热脱胶损伤。
