Koj puas xav txog? Ib qho "qhov khoom siv" uas ib zaug tau siv nyob rau hauv foob pob hluav taws thiab cua turbine hniav yog tam sim no rov sau keeb kwm ntawm kev txhim kho lub tsev - nws yogcarbon fiber mesh.
- Aerospace noob caj noob ces nyob rau hauv 1960s:
Kev lag luam tsim cov carbon fiber filaments tso cai rau cov khoom no, uas yog cuaj lub sij hawm muaj zog dua hlau tab sis peb-quarters sib dua, yuav tsum tau qhia rau noob neej thawj zaug. Thaum xub thawj tseg rau "cov neeg tseem ceeb sectors" xws li aerospace thiab high-end cov khoom ua si, nws tau woven siv cov tsoos textile cov tswv yim, tab sis nws muaj peev xwm tig lub ntiaj teb upside down.
- Lub ntsiab lus tig hauv "kev ua tsov rog ntawm steel":
Cov pa hluav taws xob ntxiv yog zoo li "qub codger" ntawm lub ntiaj teb kev tsim kho: nws hnyav npaum li tus ntxhw (kwv yees li 25 kg ib square meter ntawm reinforcing mesh), thiab tseem ntshai ntsev, dej, thiab sij hawm - - Chloride ion yaig ua rau cov hlau reinforcement nthuav thiab tawg.
Qhov tshwm sim ntawmcarbon fiber mesh daim ntaubUa tiav qhov kev tsis sib haum xeeb: los ntawm kev taw qhia weaving + epoxy resin impregnation, nws ua rau lub thickness ntawm lub reinforcing txheej los ntawm 5cm mus rau 1.5cm, qhov hnyav tsuas yog 1/4 ntawm rebar, tab sis kuj resistant rau acid thiab alkali, seawater, thiab nyob rau hauv lub reinforcement ntawm tus choj ntawm hiav txwv, tsis muaj kos npe rau ntawm corrosion rau 20 xyoo.
Vim li cas cov engineers maj nrawm siv nws? Tsib hardcore zoo tau nthuav tawm
| Qhov zoo | Cov tsoos steel reinforcement / carbon fiber daim ntaub vs carbon fiber mesh daim ntaub | Lub neej piv txwv |
| Lub teeb zoo li plaub, muaj zog li hlau | 15 hli tuab txheej txheej tuaj yeem tiv taus 3400MPa tensile force (sib npaug rau 1 chopstick los tuav 3 tus ntxhw), 75% sib dua li lub rebar | Zoo li mus rau lub tsev kom hnav "pob mos txwv undershirt", tab sis tsis nce qhov hnyav |
| Kev tsim kho zoo li painting phab ntsa Raws li yooj yim li | Tsis muaj vuam, khi, ncaj qha tshuaj tsuag polymer mortar, lub tsev kawm ntawv qhov kev txhawb nqa hauv Beijing nrog nws kom luv lub sijhawm tsim kho los ntawm 40% | Txuag ntau tshaj tiling, cov neeg zoo tib yam tuaj yeem kawm tau |
| Hluav taws kub los tsim kom muaj kev npau taws | 400 ℃ siab kub lub zog tseem tsis hloov pauv, lub khw muag khoom txhawb nqa los ntawm kev lees txais hluav taws, thaum cov tsoos epoxy resin nplaum yuav softened hauv 200 ℃ | Zoo ib yam li hnav "tsim hluav taws" rau lub tsev " |
| Ib puas xyoo tsis phem 'preservative' | Cov pa roj carbon fiber ntau yog cov khoom siv tsis zoo, siv rau hauv cov nroj tsuag tshuaj hauv qhov chaw muaj zog acidic rau 15 xyoo yam tsis muaj kev puas tsuaj, thaum lub rebar tau ntev rusted rau hauv slag. | dua li cov hlau tsis muaj hlau kuj tseem tiv taus kev tsim khoom "cov tshuaj tiv thaiv kev tsim kho" |
| Ob txoj kev tiv thaiv seismic "martial arts master" | longitudinal thiab transverse kev taw qhia tuaj yeem tensile, tom qab av qeeg, lub tsev kawm ntawv tau txhawb nqa nrog nws, thiab tom qab ntawd ntsib qhov kev poob siab ntawm qib 6 tsis muaj qhov tawg tshiab. | nyiam mus rau lub tsev uas muaj "shock-absorbing springs" |
tseem ceeb:kev tsim kho yuav tsum tau siv kom phim cov tshuaj khib nyiab polymer! Ib lub zej zog tau ua yuam kev siv cov tshuaj khib nyiab, ua rau cov txheej txheem ntawm cov nruas thiab poob tawm - ib yam li kev siv cov kua nplaum los lo iav, cov kua nplaum tsis yog txoj cai sib npaug ntawm kev ua haujlwm pov tseg.
Los ntawm Lub Nroog Forbidden mus rau Hla Hla Hla Hiav Txwv: Nws Hloov Lub Ntiaj Teb ntsiag to
- Lub "Invisible Bandage" rau Cultural Heritage thiab Ancient Buildings:
Lub Beyer Bau, ib puas xyoo lub tsev ntawm Technische Universität Dresden nyob rau hauv lub teb chaws Yelemees, yog nyob rau hauv kev xav tau kev pab ntxiv vim muaj zog loads, tab sis tau raug txwv los ntawm kev tiv thaiv monument. Cov kws ua haujlwm nrog 6 hli tuab carbon fiber mesh daim ntaub + nyias txheej ntawm mortar, nyob rau hauv qab ntawm lub nqaj "pas" ib txheej ntawm "pob tshab band-pab", tsis tsuas yog kom lub load-bearing muaj peev xwm los txhim kho 50%, tab sis kuj tsis hloov lub tsev nyob rau hauv lub slightest thawj tsos, thiab txawm lub cuab yeej cuab tam Board kws txawj tau qhuas: ".
- Traffic engineering "super thaj":
Florida, Tebchaws Asmeskas, cov kab hla hiav txwv hla, ntxiv nrog cov pa roj carbon fiber ntau hauv xyoo 2003, lub zog los ntawm "tsis muaj zog" tau nce 420%, thiab tam sim no 20 xyoo tom qab, nag xob nag cua tseem nyob ruaj khov li lub roob ntawm ntug dej hiav txwv. Hauv Hong Kong-Zhuhai-Macao Choj Island qhov project, kuj ntsiag to siv nws los ua cov txheej txheem txhim kho, tiv thaiv dej hiav txwv yaig.
- "Lub hnub nyoog-reversing khawv koob riam phom" ntawm qub thiab ploj mus me me:
Hauv ib cheeb tsam 80's hauv Beijing, cov slabs hauv pem teb tau tawg heev, thiab cov phiaj xwm qub yog los tsoo thiab tsim kho dua tshiab. Tom qab nrog carbon fiber mesh daim ntaub + polymer mortar reinforcement, tus nqi ib square meter tsuas yog 200 yuan, dua li reconstruction ntawm 80% ntawm cov nqi txuag, thiab tam sim no cov neeg nyob hauv hais tias: "Xav txog lub tsev hluas 30 xyoo!
Lub neej yav tom ntej nyob ntawm no: Kev kho tus kheej, saib xyuas "cov ntaub ntawv ntse" tab tom ua
- Ib tug "tus kws kho mob tus kheej" hauv pob zeb:
Cov kws tshawb fawb tab tom tsim cov pa roj carbon fiber mesh uas "kho nws tus kheej" - thaum microcracks tshwm sim hauv cov qauv, cov mesh tuaj yeem siv los ua kev txhawb nqa. - Thaum microcracks tshwm sim hauv cov qauv, cov tshuaj ntsiav hauv cov khoom tawg kom tso cov neeg ua haujlwm kho uas tuaj yeem sau cov kab nrib pleb. Kev sim ntawm ib lub chaw kuaj mob hauv UK tau pom tias cov khoom siv tuaj yeem txuas lub neej ntawm pob zeb mus txog 200 xyoo.
- Ib qho "health bracelet" rau cov tsev:
embeds fiber-optic sensors nyob rau hauv lubcarbon fiber mesh, zoo li "smart watch" rau cov tsev: lub tsev cog khoom hauv Shanghai siv nws los saib xyuas kev sib haum xeeb thiab kev tawg ntawm lub sijhawm, thiab cov ntaub ntawv raug xa ncaj qha mus rau lub chaw tswj xyuas rov qab, uas yog 100 npaug ntau dua li cov kev tshuaj xyuas ib txwm muaj. Nws yog 100 npaug ntau dua li kev tshuaj xyuas phau ntawv ib txwm muaj.
Conscientious tswv yim rau engineers thiab tswv
1. Cov ntaub ntawv xaiv qhov yog, ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog:paub txog cov khoom uas muaj zog tensile ≥ 3400MPa thiab modulus ntawm elasticity ≥ 230GPa, thiab koj tuaj yeem nug cov tuam ntxhab kom muab cov ntawv xeem.
2. Tsis txhob tub nkeeg hauv kev tsim kho:lub hauv paus nto yuav tsum tau polished huv si, thiab lub polymer mortar yuav tsum tau tov raws li qhov kev faib ua feem.
3. Lub tsev qub kev kho dua tshiab tseem ceeb:piv nrog kev rhuav tshem thiab kev tsim kho dua tshiab, carbon fiber mesh reinforcement tuaj yeem khaws qhov zoo li qub ntawm lub tsev, tab sis kuj txuag tau ntau dua 60% ntawm tus nqi.
Xaus
Thaum cov ntaub ntawv aerospace "mus rau hauv lub ntiaj teb" mus rau qhov chaw tsim kho, peb mam li nco dheev pom: qhov kev txhawb nqa thawj zaug tsis tuaj yeem ua kom muaj zog, lub tsev qub qub tuaj yeem yog "rov qab kev loj hlob".Carbon fiber mesh daim ntaubNws zoo li "superhero" hauv kev tsim kho kev lag luam, nrog lub teeb, muaj zog thiab ruaj khov yam ntxwv, yog li txhua lub tsev qub muaj lub sijhawm los kho nws lub neej - thiab qhov no tsuas yog qhov pib ntawm cov khoom hloov pauv.
