Figure 15 is the sectional view at the position of the arrow B representing Figure 13, and car walls 24 also FRP formed body 1 is as shown in Figure 1 formed, and inner side is formed with opening portion 5.In addition, the FRP4 of inner side is provided with the decorative panel 4 be such as made up of metal forming.
In the elevator 22 of present embodiment, because car walls 24 is made up of FRP formed body 1, so make an uproar by FRP4 and the sound insulation of hard separated foam body 3 from the wind outside car.In addition, the sound wave of the dialogue in car etc. is absorbed by the continuous air bubbles body 2 exposed by opening portion 5, so can suppress the echo of the sound of the dialogue in car etc.
In addition, when FRP formed body 1 is directly used in car walls 24, opening portion 5 is externally exposed, and aesthetic property is bad, but in the present embodiment, decorative panel 27 covers this opening portion 5, can not damage aesthetic property.In addition, because decorative panel 27 is made up of thin metal forming, so almost do not have sound insulation function, sound wave is absorbed by continuous air bubbles body 2 by opening portion 5.
In addition, because radome fairing 25 is also made up of FRP formed body 1, so make an uproar by FRP4 and the sound insulation of hard separated foam body 3 from the wind outside car.In addition, the noise being configured in the electrical equipment 26 of the pressure fan of the inner side of radome fairing 25 etc. is absorbed by continuous air bubbles body 2 by opening portion 5, suppresses noise to the transmission in car.
Below, effects on surface is that the manufacture method of the radome fairing 25 of the hat of curved surface is described.
When manufacturing the radome fairing 25 of the curve form that each surface bloats, first, prepare curved shaping dies, by structure figuration (setting) in this shaping dies.
As shown in Figure 6, in this structure, cover continuous air bubbles body 2 by the order of hard separated foam body 3, FRP4, peel ply 10, flow media 11 and bag-shaped film 12.
About this structure, by vavuum pump 13 to decompression in bag-shaped film 12, then resin 14 is injected in bag-shaped film 12, resin 14 is immersed in FRP4, and resin 14 is solidified.
Then, removing peel ply 10, flow media 11, bag-shaped film 12, do not formed the structure of opening portion 5.
Then, hole in a face of this structure, form opening portion 5, complete the radome fairing 25 be made up of FRP formed body 1 thus.
In addition, flow media 11, peel ply 10, bag-shaped film 12, FRP4 and continuous air bubbles body 2 can easily figuration be in curved shaping dies deviously, but hard separated foam body 3 is difficult to bending 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 the bending forming of hard separated foam body 3 can be carried out, as shown in figure 17, on the surface of the hard separated foam body 3 of inner side, form multiple groove 28 extended on the direction vertical relative to bending direction at spaced intervals.
But, for not damaging the function preventing resin-dipping, the outside of hard separated foam body 3 must not be extended through.
In addition, the shape of groove 28 is not particularly limited, but preferred V-shaped.
And the hard separated foam body 3 of Figure 17 bends to the direction defining groove 28, but also can bend on the contrary.In this situation, groove 28 is expanded, and remaining resin 14 is filled and becomes heavy, but resin stream when can be shaped as VaRTM is applied in a flexible way, and can remove the flow media 11 between shaping dies and FRP4.And after shaping, the resin 14 remained in groove 28 becomes rib, obtains the stiffening effect of radome fairing 25.
In addition, about the car walls 24 be made up of FRP formed body 1, for the bending forming of hard separated foam body 3 can be carried out, on the surface of hard separated foam body 3, the multiple groove 28 extended on the direction vertical relative to bending direction of formation spaced apart.
In addition, the car walls 24 of the elevator 22 of present embodiment, radome fairing 25 employ the FRP formed body 1 of embodiment 1, but can certainly use FRP formed body 1A, 1B, 1C of embodiment 2 ~ 4.
In addition, elevator 22 that use in present embodiment, that employ car walls 24 and radome fairing 25 is not limited to express elevator certainly.
