4 are joined together. In addition, the outer skin 2 is constructed as a single piece that extends from one side of the sandwich wood through the end face of the core material 1 to the other side, but it is not necessary to do so; The core material 1 may be a separate body, and the end surface of the core material 1 may be exposed. However, if the outer skin is also present on the end face of the core material 1 as an integral piece, not only will the interlaminar shear properties of the sand German timber be improved, but also, for example, when constructing a trunk as shown in Fig. 2, the end face mating surface 5,
5, ..., which not only improves the design effect, but also eliminates the need to attach aluminum sash etc. to the mating surfaces, which is preferable.

That is, using a sandwiched German timber made by bonding the outer skin 2 made of FRP to one side of the core materials 3, 3 made of a hard foam or a honeycomb body, and FRP 4 on the other side, the part corresponding to the bending center of the sandwiched German timber is used. As shown in the figure, after cutting out the outer skin 2 in a U-shape leaving only the outer skin 2, apply adhesive to the cut surface and FRP 4, fold it in half upward in the drawing so that the FRP 4 side is inside, and join. It can be manufactured by

The FRPs 4, 4 do not extend to the end face of the core material 1. As shown in FIG. 5, such a sandwich material can be manufactured in the same manner as explained in FIG. 3 by cutting out the portion corresponding to the bending center in a W-shape.

できるようになる。(Effect of the invention) The core material of the Sanderutsch material of this invention is not composed only of hard foam or honeycomb, but has a layered structure of that and FRP. When the core material
FRP blocks shock well and creates through holes,
This greatly reduces the risk of creating a large sinkhole. Furthermore, when a surface receives an impact, it is possible to prevent cracks from forming in the core material and from reaching the opposite surface.
