Tsim kom muaj kev nyab xeeb, muaj zog, thiab ntse dua: Lub luag haujlwm tseem ceeb ntawm kev sib xyaw ua ke hauv kev tsim kho niaj hnub

3.1 Reinventing Infrastructure: Hloov los ntawm cov khoom siv niaj hnub mus rau siab -Kev ua tau zoo Composites

Kev tsim kho thoob ntiaj teb thiab kev tsim vaj tsev hauv pej xeem, lub luag haujlwm rau kev tswj hwm thiab txhim kho peb cov txuas hniav, cov tsev, thiab cov qauv keeb kwm, yog nyob rau hauv nruab nrab ntawm lub kiv puag ncig ntsiag to. Tau ntsib nrog cov kev sib tw ntxaib ntawmkev laus infrastructurethiab kev xav tau ntawm kev tsim kho sai, resilient, engineers tau tig tawm ntawm cov khoom siv ib txwm muaj xws li steel thiab pob zeb rau kev txhawb nqa thiab mus rauadvanced fiber ntau-cov khoom siv polymers (FRP). Ntawm cov no,carbon fiber reinforced polymer (CFRP)cov tshuab tau tshwm sim los ua ib qho kev daws teeb meem zoo tshaj plaws rau kev txhim kho cov txheej txheem, kho, thiab txawm tias nyob rau hauv cov ntawv tshiab - tsim cov ntawv thov. Tus tsav tsheb yog kev ua tau zoo: CFRP fabrics thiab laminates muabcorrosion kuj, siab tensile zog, thiab lub zog - rau - luj pivuas yog superior rau steel, tag nrho thaum ua tau zoo heev ceev thiab yooj yim rau nruab nrog tsawg cuam tshuam.

Daim ntawv thov tsim tshaj plaws yog nyob rau hauvseismic retrofitting thiab ntxiv dag zogntawm cov vaj tse pob zeb. Cov kab, kab teeb, thiab slabs tuaj yeem qhwv los yog sab nraud nrog CFRP fabrics, ua rau lawv loj tuaj.ductility, shear zog, thiab load- bearing peevtsis ntxiv qhov loj loj lossis hloov cov qauv geometry. Qhov no yog qhov tseem ceeb rau kev coj cov tsev laus thiab cov txuas hniav mus rau cov cai niaj hnub kev nyab xeeb. Tshaj li kho, CFRP kuj tseem siv rau hauvchoj decks, architectural facades, thiab precast ntsiab, ua kom sib dua, ntev dua - ncua, thiab tsim kom muaj tswv yim ntau dua. Rau cov thawj coj ntawm qhov project, engineers, thiab cov neeg cog lus, kev nkag siab yuav ua li cas qhia thiab siv cov tshuab sib xyaw no yog qhov tseem ceeb rau kev xa cov haujlwm uas tsis yog muaj zog thiab ruaj khov dua, tab sis kuj muaj ntau dua.tus nqi- zoo thiab ruaj khovntawm lawv lub neej tag nrho. Kab lus no tshuaj xyuas cov kev xav tau thiab cov kev coj ua zoo tshaj plaws rau kev siv cov pa roj carbon fiber ntau hauv kev tsim kho, hloov txoj hauv kev uas peb tsim thiab tsim peb lub ntiaj teb.

3.2 Kev xaiv cov khoom siv thiab kev tsim qauv: Engineering rau cov kev xav tau tshwj xeeb

Kev vam meej hauv kev tsim kho kev siv yog nyob ntawm kev xaiv txoj cai ntawm cov ntaub ntawv carbon fiber ntau thiab tsim cov txheej txheem kev txhawb nqa los daws cov teeb meem tshwj xeeb. Tsis zoo li cov qauv steel rebar, FRP cov kev daws teeb meem yog hloov tau yooj yim.

Npuag Architecture rau kev thauj khoom tshwj xeeb:Kev xaiv ntawm cov ntaub weave ncaj qha cuam tshuam rau nws txoj haujlwm engineering.

Unidirectional (UD) Fabrics:Cov no yog cov workhorse rau flexural thiab tensile ntxiv dag zog. Nrog ntau dua 90% ntawm cov fibers ua ke nyob rau hauv ib qho kev taw qhia, UD fabrics muab qhov siab tshaj plawslub zog thiab nrujnyob ntawm qhov axis. Lawv feem ntau yog siv los txhawb cov kab teeb thiab slabs nyob rau hauv cov kev taw qhia ntawm thawj tensile kev nyuaj siab, ua tau zoo raws li sab nraud reinforcement.

Bidirectional Woven Fabrics (piv txwv li, Plain Weave, 2x2 Twill):Cov ntaub no muab lub zog nyob rau hauv ob qho kev qhia orthogonal (0℃thiab 90 degree). Lawv yog cov zoo tagnrho rauconfinement thiab shear strengtheningkev siv, xws li wrapping pob zeb kem. Qhov kev kaw cia siab lawv thov tom qab resin impregnation ua rau cov kab ke nce ntxivcompressive zog thiab ductility, uas yog qhov tseem ceeb rau kev ua haujlwm seismic. Woven fabrics kuj muab kev tuav zoo dua thiab ua raws li cov duab nyuaj.

Tsis yog -Crimp Fabrics (NCF):Thaum tsis tshua muaj nyob rau hauv daim teb - siv cov layup ntub dej, NCFs (nrog fibers stitched nyob rau hauv ntau cov lus qhia xws li 0℃, +45℃, 90℃, -45℃) yog siv nyob rau hauv prefabricated CFRP daim hlau los yog plhaub rau tej yam, muaj kev ua tau zoo ntxiv dag zog rau tej yaam num.

Tsim Codes thiab Compatibility:Cov kws tshaj lij yuav tsum tsim raws li kev lees paub thoob ntiaj teb lossis lub tebchaws, xws li ACI 440 (USA), fib Bulletin 90 (International), lossis TR55 (UK). Cov lis dej num no muab cov lus qhia rau kev xam qhov xav tau ntawm CFRP raws li qhovcov qauv uas twb muaj lawm, qhov xav tau nce hauv lub peev xwm, thiab qhov ntev - lub sij hawm durability yam. Tsis tas li ntawd, lub compatibility ntawm lubcarbon fiber ntaub, saturating resin (epoxy), thiab pob zeb substrateyog qhov tseem ceeb. Cov resin yuav tsum tau ntub cov fibers kom zoo, sib cog lus rau cov pob zeb, thiab muaj qhov haum iav hloov qhov kub (Tg) rau qhov chaw pabcuam kom ntseeg tau ntev - lub sijhawm ua haujlwm.

3.3 Ntawm -Site Execution thiab Quality Assurance: Ua kom ntev -Lub Sij Hawm Ua Haujlwm

Cov khoom zoo tshaj ntawm CFRP tuaj yeem cuam tshuam los ntawm kev teeb tsa tsis zoo. Hauv kev tsim kho, kev tswj kom zoo ntawm daim ntawv thov daim teb yog qhov tseem ceeb raws li qhov zoo ntawm cov khoom xa tuaj.

Surface Preparation thiab Priming:Ib kauj ruam tseem ceeb tshaj plaws yog kev npaj ntawm pob zeb substrate. Nws yuav tsum yog suab, huv si, thiab zoo profiled (feem ntau los ntawm grit blasting) kom paub meej amechanical bond. Txhua qhov tawg yuav tsum tau txhaj, thiab cov ces kaum yuav tsum tau muab sib npaug los tiv thaiv kev ntxhov siab hauv CFRP. Tom qab ntawd ib qho kev tsim primer los yog putty yog siv los sau cov voids thiab tsim ib qho chaw zoo rau lub laminate.

Impregnation thiab Layup:Rau cov txheej txheem ntub dej, cov ntaub yuav tsum tau saturated nrog epoxy resin, tshem tawm tag nrho.huab cua npuas thiab chaw qhuavuas yuav dhau los ua cov ntsiab lus tsis ua haujlwm. Qhov no yuav tsum muaj cov txheej txheem rau cov menyuam kom raug thiab, qee zaum, kev siv lub tshuab nqus tsev ntim khoom kom ntseeg tau tias kev sib khi thiab tshem tawm cov resin ntau dhau. Kev taw qhia thiab kev ua kom zoo ntawm cov ntaub, tshwj xeeb tshaj yog UD fabrics, yuav tsum tau tswj kom meej raws li cov duab kos duab engineering.

Independent Verification thiab Testing:Cov dej num muaj koob npe feem ntau koom nrog thib peb -kev tshuaj xyuas thiab kev sim. Qhov no tuaj yeem suav nrogrub- tawm kev xeemtxhawm rau txheeb xyuas lub zog ntawm CFRP thiab cov pob zeb, lossisqauv daim couponua rau ntawm -qhov chaw thiab xa mus rau ib lub chaw kuaj xyuas tshuab. Tus neeg muag khoom lub luag haujlwm txuas mus rau kev muab cov ntaub ntawv nrog cov khoom sib xws, muaj ntawv pov thawj thiab txhawb nqa tus neeg cog lus kom meejdaim ntawv thov cov txheej txheem thiab cov ntaub ntawv technicallos pab kom muaj kev ruaj ntseg zoo.

3.4 Lub YIXIN Foundation: Muab kev ntseeg siab rau cov phiaj xwm tseem ceeb

Haining YIXIN New Material Co., Ltd. muab kev lag luam kev tsim kho nrog kev ua haujlwm siab - cov pa roj carbon fiber ntau cov ntaub uas tsim cov pob txha ntawm cov txheej txheem txhim khu kev qha.
