Nrog rau kev txhim kho ntawm cov thev naus laus zis tsim cov khoom sib xyaw, nrog rau kev nkag siab tob txog cov khoom sib xyaw hauv kev lag luam tsheb ciav hlau, nrog rau kev nce qib ntawm kev siv tshuab ntawm kev lag luam tsim tsheb ciav hlau, qhov kev siv cov khoom sib xyaw hauv cov tsheb ciav hlau tau nthuav dav maj mam. Cov hom, qib thiab cov theem kev siv ntawm cov khoom sib xyaw siv kuj tseem niaj hnub txhim kho.
Cov hom ntaub ntawv sib xyaw uas tau siv rau hauv cov tsheb thauj neeg hlau muaj xws li:
(1) Rigid thiab semi-rigid unsaturated polyester resin FRP;
(2) Phenolic resin iav fiber reinforced yas;
(3) Cov nplaim taws tsis zoo uas tsis muaj zog polyester resin FRP uas muaj zog heev;
(4) Cov khoom siv hluav taws xob ntxiv uas tsis muaj roj polyester resin iav fiber reinforced yas nrog lub zog qis dua me ntsis;
(5) Cov khoom siv carbon fiber.
Los ntawm cov ntsiab lus ntawm cov khoom yog:
(1) Cov khoom FRP uas muab tso rau tes;
(2) Cov khoom FRP uas tau pwm;
(3) FRP qhov chaw ntawm cov qauv sandwich;
(4) Cov khoom siv carbon fiber.
Daim ntawv thov ntawm FRP hauv Tsheb Thauj Neeg Hlau
1. Kev siv FRP thaum ntxov hauv cov tsheb thauj neeg hlau
Daim ntawv thov ntawm FRP hauv cov tsheb ciav hlau pib xyoo 1980, thiab nws tau siv thawj zaug hauv cov tsheb ciav hlau hluav taws xob ceev qis 140km / h uas tsim tawm hauv tebchaws. Qhov ntau thiab tsawg ntawm daim ntawv thov feem ntau suav nrog:
● vaj huam sib luag sab hauv phab ntsa;
● sab hauv sab saum toj phaj;
● Chav dej yas ua los ntawm cov iav fiber ntau uas sib dhos ua ke;
Lub hom phiaj tseem ceeb ntawm kev siv thaum lub sijhawm ntawd yog Katsukiyogi. Hom FRP siv yog unsaturated polyester resin FRP.
2. Kev siv FRP ntau rau ntawm cov tsheb ciav hlau
Daim ntawv thov ntau ntawm FRP rau ntawm cov tsheb ciav hlau thiab nws qhov kev loj hlob maj mam tshwm sim hauv xyoo 1990. Nws feem ntau yog siv rau kev tsim cov tsheb ciav hlau thiab cov tsheb ciav hlau hauv nroog:
Lub vaj huam sib luag sab hauv ntawm chav qhua;
●Phaj sab hauv sab saud;
Chav dej yas ua los ntawm cov iav fiber ntau ua ke;
Chav dej yas uas muaj fiber ntau ntxiv rau hauv iav;
Chav dej yas uas muaj fiber ntau iav sib xyaw ua ke;
FRP cua txias duct, pov tseg pa phem duct;
● Lub rooj zaum lossis lub thav duab rooj zaum.
Lub sijhawm no, lub hom phiaj tseem ceeb ntawm daim ntawv thov tau hloov ntawm kev hloov ntoo mus rau kev txhim kho qib ntawm cov tsheb; cov hom FRP siv tseem yog cov tsis muaj polyester resin FRP.
3. Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm FRP hauv tsheb ciav hlau
Txij li thaum pib ntawm lub xyoo pua no, FRP tau siv dav dua hauv cov tsheb ciav hlau. Ntxiv nrog rau kev siv rau hauv kev tsim cov khoom lag luam sib txawv uas tau hais los saum toj no, nws kuj tseem siv dav hauv kev tsim khoom ntawm:
● Lub ru tsev npog;
Ib lub qhov cua tshiab rau saum lub ru tsev;
●Ntau yam khoom sib txawv uas muaj cov duab sib txawv hauv lub tsheb, suav nrog cov vaj huam sib luag sab hauv uas nkhaus peb sab thiab cov vaj huam sib luag sab ru tsev; cov vaj huam sib luag npog ntawm ntau yam duab tshwj xeeb; cov vaj huam sib luag phab ntsa yas ua los ntawm iav fiber ntxiv rau hauv cov honeycomb; cov khoom dai kom zoo nkauj.
Lub hom phiaj tseem ceeb ntawm kev siv FRP ntawm theem no yog los tsim cov khoom uas muaj cov kev xav tau tshwj xeeb lossis cov qauv nyuaj. Tsis tas li ntawd, qhov kev tiv thaiv hluav taws ntawm FRP siv rau theem no kuj tau txhim kho. Cov tshuaj reactive thiab additive flame retardant unsaturated polyester resin FRP tau siv dav, thiab kev siv phenolic resin FRP tau maj mam txo qis.
4. Kev siv FRP hauv EMU ceev ceev
Daim ntawv thov ntawm FRP hauv kev tsheb ciav hlau ceev ceev EMUs tau nkag mus rau theem paub tab. vim tias:
(1) FRP yog siv rau hauv kev tsim cov khoom nrog cov haujlwm tshwj xeeb, cov duab thiab cov qauv nyuaj, thiab kev ua tau zoo heev uas tuaj yeem tiv taus cov khoom loj, xws li FRP integral streamlined fronts, pem hauv ntej qhib thiab kaw mechanism modules, ru tsev aerodynamic shrouds, thiab lwm yam.
(2) Cov yas fiber ntau ntxiv rau cov iav (SMC) tau siv dav heev
Kev siv cov iav fiber reinforced yas los tsim cov EMU ceev ceev sab hauv phab ntsa vaj huam sib luag hauv cov khoom muaj cov txiaj ntsig zoo li nram no:
Qhov tseeb ntawm qhov chaw yog siab;
● Kev tsim khoom zoo thiab qib khoom,
● Ua tiav qhov sib dua;
● Haum rau kev tsim khoom loj.
(3) Txhim kho qib ntawm FRP siv rau lwm qhov chaw
●Nws tuaj yeem ua rau hauv cov khoom nrog ntau yam qauv raws li qhov xav tau;
Qhov zoo li zoo dua, thiab qhov zoo li cas thiab qhov ntev ntawm cov khoom yog siab dua;
● Xim thiab qauv ntawm qhov chaw tuaj yeem hloov kho tib lub sijhawm.
Lub sijhawm no, daim ntawv thov ntawm FRP suav nrog kev paub txog cov haujlwm tshwj xeeb thiab cov duab, thiab cov hom phiaj siab dua xws li kev nqa ib qho kev thauj khoom thiab qhov hnyav.
