し、さらに、押圧して型締めする。 Following this installation process, a mold clamping process is performed. This mold clamping process is a process of clamping the honeycomb material 1 in the above state, the special films 8, 9, the face materials 2, 3, and the adhesives 10, 10 with a predetermined mold clamping force,
As shown in F, the upper mold 22 is aligned with the lower mold 21, and the molds are clamped by pressing.

圧力の分布に対応しているといえる。 Then, the resins 10, 10 are pressed between the face materials 2, 3 and the special films 8, 9, and spread evenly between them, and since the special films 8, 9 have permeability, the resin 10, 10 , 10 penetrate uniformly into the special films 8, 9, and seep out to the honeycomb material 1 side, as shown in FIG. The penetrating power of the adhesives 10, 10 increases, and the amount of resin penetrating into this portion becomes larger than the other portions. That is,
It can be said that the amount of resin 10 seeping out toward the honeycomb material 1 corresponds to the distribution of the pressing force between the honeycomb material 1 and the special films 8 and 9.
このようにして、樹脂１０，１０が、面材２，

いる。 Therefore, the permeability of the special films 8 and 9 is as follows:
This is largely related to the particle size and viscosity of the resin 10, and the mold clamping force required to spread the resin 10 uniformly between the face materials 2 and 3 and the special films 8 and 9 is such that the resin 10 does not penetrate much. This is what has been set. In this example, a mixture of urethane and unsaturated polyester is used as the resin 10, and the mixture ratio is in the range of 1:3 to 1:6 by weight. ,9
It has been found through experiments that it is preferable in terms of good spreadability between the layers and permeability to the special films 8 and 9.

少なく、製造が非常に簡単である。 As described above, according to the present manufacturing method, the face material 2,
Without uniformly applying the resin (adhesive) to one surface of the mold 23, and without pre-impregnating the special films 8 and 9 with the resin (adhesive) 10, the mold 23 is simply molded. By tightening, the special films 8, 9 are impregnated with the resin 10, and the face materials 2, 3 and the honeycomb material 1 are bonded, so that the number of manufacturing steps is small and the manufacturing is very simple.
また、樹脂１０が型締め力により広げられるた

ていても、均一に広がつて特殊フイルム８，９に
含浸されるもので、特に、この点で上記のように
樹脂を塗布したり予め含浸させる場合と比べて優
れている。 In addition, since the resin 10 is spread by the mold clamping force, even if the face materials 2, 3, etc. are formed in a curved shape, the resin 10 spreads uniformly and is impregnated into the special films 8, 9. In this respect, it is superior to the case where the resin is applied or pre-impregnated as described above.
次に、第３図に基づき、請求項２の製造方法の
実施例について説明する。 Next, an embodiment of the manufacturing method according to claim 2 will be described based on FIG.

After the installation process of stacking the special film 208, honeycomb material 1, special film 208, and face material 3 in this order,
A mold clamping process for clamping the upper mold 22 is performed.
尚、この実施例では、特殊フイルム２０８は袋

型２１の成形面２２１，２２１の間隔の方がその
間隔分だけ広く設定されている。尚、２２１は上
型２２の成形面である。 In addition, in the case of this embodiment, when the mold is clamped, no mold clamping force is applied to the face materials 2, 3, the special film 208, and the honeycomb material 1;
and the special film 208 at a predetermined interval (for example,
5 to 10 mm), that is, the molding surface 221 of the upper mold 22 and lower mold 21 is thicker than the total thickness of the face materials 2 and 3, the special film 208, and the honeycomb material 1. , 221 is set wider by that distance. Note that 221 is the molding surface of the upper mold 22.
