すると、以下の表ー１のようになる。Then, the laminated body thus assembled is heated under pressure by a heat curing device (not shown) such as a hot press method, an autoclave or a vacuum bag method using a vacuum, to heat the fiber-reinforced resin sheet. The resin is melted and adhered to the honeycomb core 3 and the surface plates 5a and 5b and integrally cured, thereby integrally adhering. After that, the integrally bonded honeycomb sandwich panel 1 is taken out from the heating and curing device, and is cleaned and finished to complete. Comparative Example 1 Next, as shown in FIG. 4, a fiber-reinforced resin layer 4 having a thickness of 0.2 mm, such as a prepreg material in which fibers are arranged in one direction, is provided on both surfaces of a honeycomb core 3 having a thickness of 18.7 mm. Thickness
A honeycomb sandwich panel 1 according to the present invention having a total thickness of 20.3 mm, which is integrally formed by laminating surface plates 5a and 5b having a thickness of 0.6 mm, and a honeycomb core 13 having a thickness of 25.4 mm, as shown in FIG. Both sides have a thickness of 0.
The following table compares the panel thickness and panel weight with the conventional honeycomb sandwich panel 10 with the total thickness of 27.0 mm, which is formed by integrally bonding the surface plates 15a and 15b made of 8 mm aluminum plate. It becomes like 1.

あった。In this case, it is assumed that both panels have the same bending rigidity. Comparative Example 2 When the high modulus type unidirectional prepreg panel according to the present invention and the conventional aluminum honeycomb sandwich panel have the same thickness, the high modulus type unidirectional prepreg panel has a higher bending rigidity. The interval (span) between the columns 2 can be increased. Therefore, in addition to reducing the weight of the panel itself, it is possible to reduce the number of struts 2 to be constructed, and thus it is possible to further reduce the weight. That is, when a floor board (floor area: 3 m × 25 m) is installed in the train, a conventional aluminum sandwich panel as shown in FIG. 5 is installed, and the span of the columns 2 is 500 mm pitch.

When the thickness of b is 0.6 mm and the total thickness of the panel is 27.0 mm, the bending rigidity of the panel is 1.95 × 10 6 Kg / mm, whereas the bending rigidity of the panel of this embodiment is 3.52 × 10 5. 6 Kg
Since it is as large as / mm, a span of 580 mm is sufficient for the strut 2 to achieve the same amount of deflection. Therefore, due to the weight reduction of the panel itself and the reduction of columns, compared to the conventional floor structure,
Weight reduction of about 16% is possible. The contents of this weight reduction are shown in Table 2 below.

By integrally molding the honeycomb core, the fiber-reinforced resin layer 4, and the surface plates 5a and 5b, the honeycomb sandwich panel 1 can be thinned by the increase in bending rigidity due to the fiber-reinforced resin layer 4. Moreover, the weight can be reduced.
