Cov ntaub ntawv puas tau siv kev lag luam tau ntau tshaj 50 xyoo. Nyob rau hauv thawj ntu kev ua lag luam, lawv tsuas yog siv nyob rau hauv cov ntawv thov high-ends xws li aerospace thiab tiv thaiv. Raws li thev naus laus zis txuas ntxiv mus ua ntej, cov khoom siv puas tau pib ua lag luam nyob rau hauv cov khoom lag luam sib txawv xws li cov khoom lag luam sib txawv, kev lag luam lag luam, cov tubrog nkoj, kev tsim khoom lag luam, kev txua khoom lag luam, txua nkoj engineering thiab kev tsim kho. Txog tam sim no, tus nqi ntawm cov khoom siv sib xyaw (cov ntaub ntawv raw thiab tsim khoom) tau tso tawm ntau xyoo, tso cai rau cov nplai loj hauv kev nce qib.
Cov khoom siv sib xyaw ua ke yog cov khoom sib xyaw ntawm cov khoom siv fiber thiab cov khoom uas muaj nyob hauv ib qho kev faib ua feem. Thaum lub resin matrix txiav txim siab cov duab kawg ntawm cov composite, cov fibers ua raws li kev txhawb nqa kom ntxiv dag zog rau cov tshuaj sib xyaw. Qhov piv ntawm cob kom muaj cov fiber sib txawv nrog lub zog thiab tawv ncauj ntawm qhov uas yuav tsum tau ua los ntawm qib 1 lossis cov khoom siv qub khoom siv (OEM).
Tus qauv txheej txheem tseem ceeb yuav tsum tau ua feem ntau ntawm cov fibers piv rau lub resin matrix, thaum lub sijhawm qib siab yuav tsum tau tsuas yog ib lub hlis ntawm cov fibers nyob rau hauv lub resin matrix. Qhov no siv rau feem ntau kev lag luam, piv tawm ntawm Resin mus rau fiber ntau yog nyob ntawm tus txheej txheem ntawm kev tsim khoom.
Marine yacht kev lag luam tau dhau los ua lub zog tseem ceeb hauv kev noj hauv ntiaj teb ntawm cov khoom siv sib xyaw, suav nrog cov ntaub ntawv ua npuas ncauj. Txawm li cas los xij, nws kuj tau ntsib kev poob qis, nrog nkoj shrbuilding qeeb thiab cov khoom lag luam nce toj. Qhov kev txo qis no tuaj yeem yog vim kev ceev faj, txo qis kev yuav khoom siv zog, thiab qhov kev pab cuam tsawg rau cov kev ua lag luam tseem ceeb. Cov nkoj nkoj tau raug kho lawv cov khoom lag luam thiab cov tswv yim kev lag luam los txo qis. Nyob rau lub sijhawm no, ntau cov nkoj nkoj me me raug yuam kom thim lossis tau txais vim xiam cov peev txheej, tsis tuaj yeem tswj hwm kev ua haujlwm zoo ib txwm. Qhov tsim ntawm yachts loj (> 55 taw) coj ib qho ntaus, thaum lub nkoj me me (<24 ko taw me me) tau ua lub ntsiab lus ntawm kev tsim khoom.
Vim li cas cov ntaub ntawv sib xyaw?
Composite cov ntaub ntawv muab ntau yam zoo tshaj cov hlau thiab lwm yam ntaub ntawv ib txwm muaj, xws li ntoo, hauv nkoj tsim khoom. Piv rau cov hlau xws li hlau los yog txhuas, cov khoom siv sib xyaw tuaj yeem txo qhov hnyav tag nrho ntawm ib feem ntawm 30 txog 40 feem pua. Qhov kev txo qis tag nrho hauv lub cev coj mus rau ntawm litany ntawm cov txiaj ntsig thib ob, xws li txo qis cov nuj nqis, qis tsev cog khoom roj emissions thiab ntau dua roj ua haujlwm. Kev siv cov khoom siv sib xyaw kuj txo qis qhov hnyav ntxiv los ntawm kev tshem tawm cov fasteners los ntawm kev sib xyaw ua ke sib xyaw.
Kev sib xyaw ua ke kuj tseem muaj nkoj cov tuam txhab tsim kev ywj pheej ntau dua, ua rau nws tsim cov khoom nrog cov duab nyuaj. Ib qho ntxiv, cov khoom sib xyaw muaj cov nqi sib tw qis dua yog tias muaj ib qho khoom sib tw vim lawv cov kev teeb tsa qis dua thiab lawv cov nqi thiab kev sib dhos ua haujlwm thiab cov kev sib dhos ua kom tsis txhob muaj qis dua. Nws tsis muaj qhov xav tau tias kev sib xyaw tau txais kev lees txais ntawm cov nkoj OEMS thiab TERER 1 tus neeg xa khoom.
Marine Composite
Txawm tias muaj cov ntaub ntawv luv ntawm cov khoom siv sib xyaw, ntau cov nkoj xa khoom thiab cov neeg xa khoom noj thiab cov neeg muag khoom yog cov ntaub ntawv ntau ntxiv yuav raug siv hauv Marine Yachts.
Thaum lub nkoj loj yuav tsum siv ntau dua li cov neeg tsav tsheb loj, yog siv ntau dua cov neeg tsav tsheb tshiab, xws li cov khoom siv roj carbon monoxide Cov hlua khi thiab cov me, tab sis cov supereryachts lossis catamarans tau ua ib feem me me ntawm kev thov nkoj me me.
Txawm tias muaj cov ntaub ntawv luv ntawm cov khoom siv sib xyaw, ntau cov nkoj xa khoom thiab cov neeg xa khoom noj thiab cov neeg muag khoom yog cov ntaub ntawv ntau ntxiv yuav raug siv hauv Marine Yachts.
Thaum lub nkoj loj yuav tsum siv ntau dua li cov neeg tsav tsheb loj, yog siv ntau dua cov neeg tsav tsheb tshiab, xws li cov khoom siv roj carbon monoxide Cov hlua khi thiab cov me, tab sis cov supereryachts lossis catamarans tau ua ib feem me me ntawm kev thov nkoj me me.
Qhov kev xav tau tag nrho rau cov nkoj suav nrog lub nkoj tsav tsheb (hauv cov chaw tsim muaj zog, tawm ntawm lub nkoj, dav hlau, chaw nres nkoj ntiag tug thiab cov nkoj caij nkoj (yachts).
Composites cov nqi yuav muaj nyob rau ntawm cov khaub ncaws sab nraud, raws li cov nqi rau iav fibers, thermosets thiab thermoplastic resins yuav nce nrog cov nqi roj crude thiab tus nqi nkag. Txawm li cas los xij, cov nqi fiber carbon fiber yuav poob rau yav tom ntej ze vim muaj peev xwm ntau dua thiab kev txhim kho lwm cov prefectors. Tab sis nws cov kev cuam tshuam tag nrho rau cov nqi ua haujlwm marine yuav tsis loj, xws li carbon fiber ntxiv ntxiv plastics account rau tsuas yog ib feem me me ntawm kev siv marine marine.
Ntawm qhov tod tes, iav fibers tseem yog cov ntaub ntawv fiber ntau rau cov khoom siv marine, thiab cov polylenters thiab vinyl esters yog cov ntaub ntawv tseem ceeb polymer yog cov khoom tseem ceeb. Polyvinyl chloride (PVC) yuav txuas ntxiv tuav cov kev sib koom ua npuas dej loj.
Raws li kev txheeb cais, iav fiber ntau cov ntaub ntawv sib xyaw (GFRP) Account rau ntau dua 80% ntawm tag nrho cov ntaub ntawv rau cov tubrog nkoj, thaum ua npuas ncauj cov ntaub ntawv ua npuas ncauj rau 15%. Tus so yog carbon fiber ntxiv ntxiv rau kom qhuav, uas yog siv nyob rau hauv cov nkoj loj thiab cov khoom siv cuam tshuam tseem ceeb hauv niche kev lag luam.
Qhov kev cog qoob loo marine composites kev ua lag luam tseem ceeb toom ib txoj kev hloov mus rau cov ntaub ntawv tshiab thiab thev naus laus zis. Tubrog marine muab cov khoom muag tau pib ua qhov kev tshawb fawb, qhia cov khoom siv tshiab, cov khoom siv qis dua, cov khoom siv fiberglass thiab woven thiab woven thiab woven thiab woven cov ntaub ntawv fiberglass. Nws yog txhua yam hais txog kev ua kom rov ua dua thiab qhov txais tau tshiab, txo cov ntsiab lus STYRENE, thiab txhim kho cov ntsiab lus txheej txheem STYILITY, thiab txhim kho cov txheej txheem txheej txheem thiab cov khoom ua tau zoo.
