Abstract
A method is for manufacturing a honeycomb structure including a core material in which a hole is formed to penetrate in a thickness direction and is arranged in a plane direction, and a skin material that is stacked on a surface of the core material. The skin material includes a thermosetting resin. The method includes half-curing the thermosetting resin by placing the skin material in a bag and heating the skin material in a state where an inside of the bag is evacuated and an outside of the bag is under an atmospheric pressure; stacking the skin material in which the thermosetting resin is half-cured onto a side of the surface of the core material; and bonding and integrating the core material and the skin material with each other by pressurizing and heating the stacked core material and skin material with the use of a sealing pressurizing heating facility.
