PROBLEM TO BE SOLVED: To provide a method for producing a honeycomb sandwich panel which can obtain a high-quality, lightweight product while eminently curtailing labor and costs. SOLUTION: In the method for producing the honeycomb sandwich panel having a honeycomb core 10 and skins of a fiber-reinforced resin composite material which are adhered to both sides of the honeycomb core, prepregs 20 and 30 are laminated on a templates 2 and 3 while deaeration compression treatment is applied to each layer, and the template 3, the prepreg 30, the honeycomb core 10, the prepreg 20, and the template 2 are laminated in turn on a surface plate 1 to form a laminate. The laminate is coated with a vacuum bag film 6, the inside of the bag film 6 is evacuated to pressurize the laminate by a first forming pressure. After that, the pressure in the bag film 6 is increased to the atmospheric pressure at a specified speed, and the bag film 6 is held for a specified length of time. The laminate is heated for a prescribed time while being pressurized by a second forming pressure through the bag film 6. COPYRIGHT: (C)2005,JPO&NCIPI |
