Fiber Reinforced Polymer Rau Lub Neej Txhua Hnub

FRP keeb kwm kev loj hlob

Txij li thaum nws tsim nyob rau hauv 1940s, FRP yog thawj zaug siv nyob rau hauv aerospace, tub rog thiab lwm yam teb. Noj cov neeg caij dav hlau ua piv txwv, qhov kev faib ua feem ntawm FRP hauv cov neeg caij dav hlau tsim khoom tau nce xyoo los ntawm xyoo, thiab ob qho tib si Boeing 787 thiab Airbus 350 tau tshaj 50 feem pua ​​(qhov hnyav piv), uas siab dua hlau, txhuas, titanium thiab lwm yam hlau. .

Thiab nws cov alloys.

Nrog kev txo qis ntawm cov nqi npaj khoom, FRP kuj tau pib nkag mus rau hauv lub neej ntawm cov pej xeem. Feem ntau siv yog iav fiber reinforced composite khoom GFRP (feem ntau hu ua iav fiber reinforced yas) thiab carbon fiber reinforced composite khoom CFRP. GFRP feem ntau yog siv rau hauv toj roob hauv pes sculptures, rooj zaum, cov thoob khib nyiab, tso tsheb hlau luam, thiab lwm yam., CFRP tuaj yeem siv hauv yachts, tsheb, tsheb kauj vab, kev ua kis las thiab khoom siv ua si, thiab lwm yam.

FRP yog thawj zaug siv nyob rau hauv pej xeem vaj tse nyob rau hauv 1960s. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1990 uas nrog kev nce ntawm FRP cov cuab yeej cuab tam rau cov cuab yeej ua vaj tse, cov neeg ua haujlwm hauv zej zog maj mam lees paub cov khoom tshiab no thiab nthuav dav rau cov hlau, ntoo, thiab cov vaj tse masonry.

FRP nta

1. Lub teeb nyhav

Qhov ceev ntawm FRP yog hais txog 14-21kN / m3, uas yog hais txog 1/6 txog 1/4 ntawm cov hlau, thiab nws kuj yog sib dua li txhuas. Thaum siv rau cov qauv loj-span, nws tuaj yeem txo qhov hnyav ntawm cov qauv. Ua piv txwv txog Txoj Haujlwm Kev Ua Yeeb Yam. Tag nrho cov pa roj carbon fiber ntau lub ru tsev hnyav tsuas yog 80t thiab tuaj yeem tsim los ntawm hoisting tag nrho. Muab xam raws li lub ru tsev txoj kab uas hla ntawm 47m, nws yog sib npaug rau qhov hnyav nruab nrab ntawm 46kg ib square meter, uas tsuas yog sib npaug li 6 hli tuab steel phaj. Xws li cov nyhuv txo qhov hnyav ua rau nws ua tau rau lub ru tsev kom dais qhov hnyav ntawm cov iav nyob ib puag ncig, tsim kom muaj cov nyhuv zoo heev.

2. Lub zog muaj zog

Muaj qhov tsis xws luag hauv cov qauv siv lead ua ntawm cov khoom siv ntuj tsim. Cov khoom siv zoo dua, tsawg dua qhov tsis xws luag thiab siab dua lub zog. Lub zog ntawm carbon fiber thiab iav fiber ntau tuaj yeem ncav cuag 10-20 npaug ntawm cov hlau. Muab rau hauv tus account lub zog sib txawv ntawm fiber ntau thiab matrix, lub zog / qhov hnyav piv ntawm FRP cov ntaub ntawv feem ntau tuaj yeem ncav cuag ntau dua 4 npaug ntawm cov hlau, ua rau qhov kawg ntawm FRP cov qauv loj-span ntau dua li cov qauv ntawm 2 mus rau 3 zaug. loj dua.

Qee cov kws tshawb fawb tau qhia txog kev siv CFRP cables los tsim lub 10, 000-m-span Gibraltar Choj, thiab nws lub zog tuaj yeem pom los ntawm qhov no.

3. Yooj yim rau daim ntawv

Cov txheej txheem tsim khoom ntawm FRP suav nrog ntau txoj hauv kev xws li pultrusion, winding, tes nteg, thiab txhaj tshuaj molding. Tsis tsuas yog FRP cov khoom lag luam nrog cov duab tsis tu ncua tuaj yeem ua rau ntawm qhov loj me, tab sis kuj tseem muaj cov nplooj ntawv ntawm yuav luag txhua yam tuaj yeem tsim los tsim cov duab kos duab tsis zoo.

4. Yooj yim rau disassemble thiab sib sau ua ke

Lwm cov nta ntawm FRP

1.Elastic modulus: Lub elastic modulus ntawm FRP yog sib npaug rau cov pob zeb thiab ntoo. Piv nrog rau nws lub zog siab, tus qauv tsim yog feem ntau tswj los ntawm deformation. Deformation tuaj yeem tswj tau los ntawm kev xaiv tsim nyog ntawm cov qauv tsim, ua ke nrog lwm cov ntaub ntawv, thiab prestressing.

2.Linear expansion coefficient: ntau me dua hlau, txhuas thiab lwm yam ntaub ntawv hlau. Ntawm ib sab, nws yuav tsis ua kom pom tseeb qhov kub thiab txias thaum siv rau ultra-ntev qauv, uas yog qhov tsim nyog rau kev tsim qauv; ntawm qhov tod tes, nws muaj cov nyhuv thermal rwb thaiv tsev zoo dua, tsis tas yuav tsum muaj txheej txheej rwb thaiv tsev ntxiv kom txuag lub tsev.

3.Fire tsis kam: Cov resin yuav mos ntawm qhov kub thiab txias thiab ua rau cov khoom siv hluav taws xob txo qis. Cov nplaim hluav taws kub hnyiab ntxiv rau FRP qhov hluav taws kub tiv thaiv txoj kev kho mob tuaj yeem siv los txhim kho qhov ua tau zoo ntawm cov khoom siv hluav taws xob. Cov nyhuv fireproof ntawm zoo-kho FRP tuaj yeem sib npaug ntawm cov pob zeb.

4.Economical: Tus nqi ntawm cov khoom siv FRP yog siab dua li cov hlau. Txawm li cas los xij, xav txog nws lub teeb yuag, lub zog siab, kev tiv thaiv corrosion, thiab kev saib xyuas qis, tus nqi tag nrho yog kev sib tw.
