た。By the way, the following problems have been pointed out in such a conventional example. Regarding a honeycomb panel, which is a structural material for joining and holding conductors such as a solar cell plate, not only is it provided with high rigidity and strength as a whole, but recently there has been a particularly strong demand for weight reduction. Since the honeycomb core, which is the core material of the honeycomb panel of this type, is made of a planar aggregate of hollow columnar cells, it has the characteristic of excellent weight ratio strength as described above, and is sufficiently rigid and strong. However, since the surface plate is made of a single plate in which an insulating sheet and a fiber reinforced plastic plate are stacked and joined, the surface plate has high rigidity and strength, but still has a problem that it is heavy. It was pointed out. That is, the honeycomb core, which is the core material that constitutes the honeycomb panel, and the surface plate have a rigidity
It is desirable to have both strength and lightness, but in the conventional honeycomb panel of this kind, in terms of rigidity and strength,
On the other hand, the surface plate has more room than the core material honeycomb core, but in terms of weight, the surface plate is heavier than the core material honeycomb core, which causes an increase in the weight of the honeycomb panel and a demand for weight reduction. It was pointed out that it was not possible to deal with it.

Yes, it is difficult to reduce the weight. On the other hand, the fiber-reinforced plastic plate that constitutes the surface plate is made of a combination of a fiber base material and a resin that are attached, impregnated, mixed, or the like.
The ratio of the fiber base material to the resin was about 6: 4.
That is, conventionally, as a fiber-reinforced plastic plate for the surface plate of the honeycomb panel, the ratio of the fiber base material to the resin is 6: 4.
Something was used as it was.

てなる。First, in this honeycomb panel 1, when the resin in the fiber reinforced plastic plates 7 and 12 of the surface plates 8 and 13 is heated and pressed in the state of the prepreg sheet 2, the prepreg sheet 2 is stained. The resin is squeezed out and squeezed out, and is adsorbed to the resin adsorption sheet 6 side through the cross sheet 5, so that the amount of resin in the fiber reinforced plastic plates 7 and 12 is greatly reduced. That is, the ratio of the fiber base material to the resin in the fiber reinforced plastic plates 7 and 12 was about 6 to 4 in the above-described conventional example of this type, whereas in the example shown in the embodiment of the present invention, The original 6: 4 is controlled to 7: 3, 8: 2, 9: 1. Then, the weight of the surface plates 8 and 13 and the honeycomb panel 1 is greatly reduced by the amount of the resin in the fiber reinforced plastic plates 7 and 12 thus reduced. Since the ratio of the fibrous base material is relatively increased, the rigidity and strength of the surface plates 8 and 13 and the honeycomb panel 1 are also increased. At the same time, since the honeycomb panel 1 uses the honeycomb core 10 that is lightweight and has high rigidity and strength as a core material, it is also extremely lightweight and has high rigidity and strength as a whole. .

る。Secondly, in such a honeycomb panel 1, an insulating sheet 3 and a fiber reinforced plastic prepreg sheet 2 to be a fiber reinforced plastic plate 7 are joined by heating and pressing to form a surface plate 8. At this time, in addition to the conventional steps, the cross sheet 5 and the resin adsorption sheet 6 are used to squeeze out and adsorb the resin in the prepreg sheet 2, so that the other steps are different from the conventional steps. It is easy and easy to manufacture. In the illustrated example, the fiber-reinforced plastic plate 12 of the surface plate 13 on the other side is also formed by using the cross sheet 5 and the resin adsorption sheet 6 and squeezing out and adsorbing the resin according to the above.
