求値を満たす製品が得られないという問題点がある。A method of hollowing out a core of a portion of a honeycomb core material to be reinforced and applying an adhesive tape to one surface of the hollowed portion is performed by directly attaching the tape to the honeycomb core surface of the honeycomb core material. The adhesive area cannot be increased and the adhesive strength cannot be increased.Therefore, the tape is peeled off from the adhesive surface of the honeycomb core material due to the heat generated by the resin or the weight of the resin, and the resin spreads to the cells of the honeycomb core other than the necessary parts,
Also, on the side opposite to the tape bonding side of the honeycomb core material, the resin is filled up slightly to prevent resin shortage, so the resin spreads to the cells of the honeycomb core other than the portion where the resin is necessary, and as a result However, there is a problem that a product that meets the designed resin filling dimension requirement value cannot be obtained.

ではできないことがある。In the method of placing the honeycomb core material on the breathable and releasable woven cloth arranged on the table, the honeycomb core surface of the woven cloth surface can be masked, but the woven honeycomb core material is woven. Regarding the masking of the surface on which the resin on the opposite side of the cloth is poured, it is necessary to mask with tape,
If the masking shape is difficult, masking may not be possible with tape.

ル内に広がることはない。In the fourth step of the method for filling the resin into the honeycomb core, tapes 12 and 12 having a larger diameter than the outer diameter of the resin filling space 11 cut from the honeycomb core are attached to one surface of the honeycomb core 1. The honeycomb core 1 to which the tape 12 is attached is arranged on the surface plate 2 with the side to which the tape 12 is attached facing down, and the resin filling space 11 of the honeycomb core 1 is placed.
Is filled with resin 13 from the upper side. Since the core and the skin layer 5 of the honeycomb core 1 to be filled with the resin are cut off from the honeycomb core 1, even if the resin 13 spreads over the skin layer 5 of the honeycomb core 1 at the time of filling the resin, the resin is filled with the resin. The resin 13 does not spread into the cells of the honeycomb core 1 except the portion to be formed.

い。In the fifth step of the method of filling the resin into the honeycomb core, the resin 13 filled in the resin filling space 11 is filled.
After being subjected to a curing treatment and completely cured, the tapes 12 and 12 and the skin layers 5 and 6 are removed from the honeycomb core 1 by peeling them off. The resin 13 cured in the resin filling space 11 is finished so as to be flush with the surrounding core surface. Since the tape 12 has an adhesive area for withstanding the heat and weight of the resin 13, it does not peel off from the adhesive surface of the honeycomb core 1.
