Xyoo 1978, London Underground ceg tsheb ciav hlau tau pib thawj lub tsheb ciav hlau nrog lub teeb yuag aluminium honeycomb composite qhov rooj hauv UK.Raws li qhov tseeb piv txwv, pab pawg Antarctic lub hnub ci lub tsheb yuav luag ua los ntawm cov khoom sib xyaw ua ke.
Txhawm rau ua kom tau raws li cov neeg caij tsheb xav tau ntau ntxiv, suav nrog cov chav dej dav dav, CET lub tank dej, qhov hluav taws xob hluav taws xob, lub tshuab cua txias, ntau lub rooj, tilting mechanisms, txhim kho cov qauv kev sib tsoo thiab thaj chaw sib tsoo, thiab cov kev hloov hauv cov cai zaum, tag nrho cov no ua rau lub tsheb ciav hlau hnyav dua.Piv txwv li, piv nrog 1970 Mk3 locomotive, 2000 Bombardier Voyager tsheb ciav hlau yog 40% hnyav dua.
Txhawm rau kom ntseeg tau tias qhov hnyav ntawm lub tsheb ciav hlau tsis tuaj yeem nce ntxiv.Lub cev plhaub, lub qhov rooj sab nrauv, bogies, HVAC, txuas txuas, tsheb tavxij, cov hlua sab hauv, cov qhov rooj sab hauv thiab cov neeg caij tsheb sab hauv (nrog rau cov rooj zaum) yog qhov tseem ceeb rau kev siv.cov ntaub ntawv sib xyawkom txo qhov hnyav.
Bombardier's AVENTRA platform tshiab siv los hloov Electrostar muaj qhov loj ntawm 30-35 tons, uas yog txo qis ntawm 17% mus rau 28% piv nrog rau yav dhau los 42-tuj tsim.Tsis tas li ntawd, lub platform tshiab siv 50% tsawg zog dua li 319 lub platform sib npaug thiab pab txo lub sijhawm mus ncig.Qhov hnyav ntawm qhov tseeb Siemens DesiroCity platform yog 25% sib zog dua qhov nruab nrab qhov hnyav ntawm lub nkoj uas twb muaj lawm hauv tebchaws Askiv, thiab kev siv lub zog siv hluav taws xob rov ua dua tshiab thiab lub teeb txuag hluav taws xob tau txo qis kev siv hluav taws xob los ntawm 50%.
Cov rooj zaum sib xyaw, cov qhov rooj sib xyaw siv cov khoom siv fiber ntau, lub nraub qaum nraub qaum, qab nthab panels, pem hauv ntej thiab kawg ntawm lub cab, lub cev sab hauv, thiab cov plag tsev nrog kev ua haujlwm zoo dua qub, suav nrog hauv pem teb npog, cua sov, cua sov / suab rwb thaiv tsev, thiab yooj yim ntxuav kev xaiv yog lwm yam thaj chaw uas cov tsheb ciav hlau tuaj yeem ua tiav qhov kev txo nqi qis dua.
Lwm cov khoom siv sib xyaw ua ke kom tau raws li qhov xav tau ntawm kev lag luam kev tsheb ciav hlau hauv ob peb xyoos tom ntej no suav nrog phenolic SMC (cov ntawv molding compound), hloov kho epoxy iav prepreg uas ua tau raws li qhov tseeb EN 45545 tus qauv tiv thaiv hluav taws,carbon fiber ntau/ phenolic prepreg, thiab nplaim-retardant ua npuas ncauj core, Thiab qhov tseeb cov ntaub ntawv thermoplastic nrog FST kev ua tau zoo.Piv nrog cov ntaub ntawv sib xyaw monolithic, muaj ob peb lub teeb yuag cov ntaub ntawv uas tuaj yeem muab rigidity thiab txo qhov hnyav ntawm tag nrho cov vaj huam sib luag.
Txawm hais tias ntuj fibers thiab bio-resin reinforced cov ntaub ntawv yog nyob rau hauv lub tshiab theem, raws li kev ntsuam xyuas ua ntej, lawv muaj peev xwm daws tau FST cov kev cai rau kev siv railway.
