On the other hand, the thermal insulation of continuous air bubbles body, sound absorption properties also good (for example, with reference to patent documentation 2).
In the separated foam body, there is the structure of the high hard of compressive strength, by this hard separated foam body is used as core, can access the good sandwich structural body of rigidity, thermal insulation and sound-proofing.
And, in recent years, for making at an easy rate relatively large sandwich structural body, usually adopt the vacuum impregnation forming process (VaRTM:Vacuum assist Resin Transfer Molding) of making sandwich structural body under the reduced pressure atmosphere that vacuumizes.
The vacuum impregnation forming process is following method: cover the fiber that is configured in shaping dies with bag-shaped film (bag film), after vacuumizing in bag-shaped film, in the bag-shaped film of aqueous resin injection, make resin-dipping in fiber and solidify, then, the Material removal mould obtains the FRP formed body.And this VaRTM method of known use is made the method that sandwich structural body is the FRP formed body, the core that above-mentioned sandwich structural body will be made of the separated foam body and the skin material combination (for example, with reference to patent documentation 3) that is made of FRP.
On the other hand, as reply noise result good method, known have a sound-absorbing sound insulation complex structure body.

In addition, in each embodiment 1～4, cover each face of upper surface, lower surface and the side of hard separated foam body 3,3A with fiber-reinforced plastic, but also can be only at upper surface and the lower surface of hard separated foam body 3,3A, fiber-reinforced plastic be set.
In addition, in each embodiment 1～4, have support 3c, 3Ac in the inside of continuous air bubbles body 2, but also can be for there is no the FRP formed body of support in inside.Under these circumstances, the hard separated foam body 3 of all sides of covering continuous air bubbles body 2, the position of 3A help to improve the rigidity of compression direction.
Figure 13 means the cutaway view of the elevator 22 of embodiments of the present invention 5.
The car of the elevator 22 of this high speed is made of car floor 23 and car walls 24.
On the top of car and the bottom radome fairing shown in Figure 16 25 that the air stream when travelling carries out rectification is installed.
Be provided with the electrical equipment 26 that is rectified pressure fans that cover 25 covers etc. on the top of car.
Figure 14 means the cutaway view at position of the arrow A of Figure 13, and radome fairing 25 is made of FRP formed body 1 shown in Figure 1, and the inboard is formed with peristome 5.
Figure 15 means the cutaway view at position of the arrow B of Figure 13, and car walls 24 also is made of FRP formed body 1 shown in Figure 1, and the inboard is formed with peristome 5.In addition, the decorative panel 4 that for example is made of metal forming is installed on the FRP4 of inboard.
In the elevator 22 of present embodiment, because car walls 24 is made of FRP formed body 1, so make an uproar by FRP4 and 3 sound insulations of hard separated foam body from the outer wind of car.In addition, the continuous air bubbles body 2 that the sound wave of the dialogue in car etc. is exposed by peristome 5 absorbs, so can suppress the echo of the sound of the dialogue etc. in car.
In addition, in the situation that FRP formed body 1 is directly used in car walls 24, peristome 5 exposes to the outside, and aesthetic property is bad, but in the present embodiment, decorative panel 27 covers this peristome 5, can not damage aesthetic property.In addition, because decorative panel 27 is made of thin metal forming, so almost there is no the sound insulation function, sound wave is absorbed by continuous air bubbles body 2 by peristome 5.
In addition, because radome fairing 25 also is made of FRP formed body 1, so make an uproar by FRP4 and 3 sound insulations of hard separated foam body from the outer wind of car.In addition, the noise of electrical equipment 26 of pressure fan etc. that is configured in the inboard of radome fairing 25 is absorbed by continuous air bubbles body 2 by peristome 5, suppresses the transmission of noise in the car.
Below, effects on surface is that the manufacture method of radome fairing 25 of the hat of curved surface describes.
When making the radome fairing 25 of the curve form that each surface bloats, at first, prepare curved shaping dies, in this shaping dies with structure figuration (setting).
As shown in Figure 6, in this structure, the order of pressing hard separated foam body 3, FRP4, peel ply 10, flow media 11 and bag-shaped film 12 covers continuous air bubbles body 2.
About this structure, by the interior decompression of 13 pairs of bag-shaped films 12 of vavuum pump, then resin 14 is injected in bag-shaped film 12, resin 14 is immersed in FRP4, and resin 14 is solidified.
Then, remove peel ply 10, flow media 11, bag-shaped film 12, obtain not forming the structure of peristome 5.
Then, hole on a face of this structure, form peristome 5, complete thus the radome fairing 25 that is consisted of by FRP formed body 1.
In addition, flow media 11, peel ply 10, bag-shaped film 12, FRP4 and continuous air bubbles body 2 can be easily figuration is in curved shaping dies agley, but hard separated foam body 3 is difficult to crooked and figuration at normal temperatures.
Especially, because of the Thermocurable of phenol foam material, and can not thermal bending.
In this radome fairing 25, for carrying out the bending forming of hard separated foam body 3, as shown in figure 17, on the surface of the hard separated foam body 3 of inboard, devices spaced apart ground forms a plurality of at the upwardly extending groove 28 in the side vertical with respect to bending direction.
But, for not damaging the function that prevents resin-dipping, must not extend through the outside of hard separated foam body 3.
In addition, the shape of groove 28 is not particularly limited, but preferred V font.
And the hard separated foam body 3 of Figure 17 is crooked to the direction that has formed groove 28, but also can be crooked on the contrary.In this situation, groove 28 expansion, remaining resin 14 is filled and becomes heavy, but the resin stream can be shaped as VaRTM the time applies in a flexible way, and can remove the flow media 11 between shaping dies and FRP4.And after shaping, the resin 14 that remains in groove 28 becomes rib, obtains the stiffening effect of radome fairing 25.
In addition, about the car walls 24 that is made of FRP formed body 1, for carrying out the bending forming of hard separated foam body 3, on the surface of hard separated foam body 3, devices spaced apart forms a plurality of at the upwardly extending groove 28 in the side vertical with respect to bending direction.
In addition, the car walls 24 of the elevator 22 of present embodiment, radome fairing 25 have used the FRP formed body 1 of embodiment 1, but can certainly use FRP formed body 1A, 1B, the 1C of embodiment 2～4.
In addition, use in present embodiment, used the elevator 22 of car walls 24 and radome fairing 25 certainly to be not limited to express elevator.
