Carbon Fiber vs iav Fiber hauv pob zeb Reinforcement

Cov cuab yeej siv cuab yeej cuab tam pob zeb tau hloov zuj zus mus deb tshaj li cov hlau qub. Nyob rau hauv xyoo tas los no, carbon fiber thiab iav fiber ntau tau tshwm sim los ua cov kev hloov tshiab, hloov pauv peb tsim cov txheej txheem niaj hnub no. Raws li kev tshawb fawb hauv kev lag luam, fiber ntau - cov pob zeb ua kom muaj zog tuaj yeem ua kom lub zog tensile ntau dua 30% thaum txo kev tawg thiab kev tu nqi. Tab sis qhov twg fiber ntau ua tau zoo tshaj plaws? Hauv tsab xov xwm no, peb yuav rhuav tshem cov pa roj carbon fiber ntau thiab cov iav fiber ntau, tshuaj xyuas lawv lub zog, kev ua haujlwm ntev, kev ua haujlwm, thiab tus nqi- yog li koj tuaj yeem txiav txim siab rau koj qhov project precast lossis cov qauv tom ntej.

Dab tsi yog Fiber Reinforced Concrete (FRC)?

Fiber-reinforced concrete (FRC) yog cov khoom siv niaj hnub sib xyaw uas txhim kho cov khoom ntawm cov pob zeb ib txwm siv los ntawm kev ntxiv cov fibers dispersed. Txawm hais tias steel fibers, iav fibers, hluavtaws fibers, los yog carbon fibers, lawv yog uniformly faib thoob plaws hauv lub pob zeb, ho txhim kho nws tensile zog, flexural zog, thiab tawg kuj.

Pob zeb muaj keeb kwm muaj lub zog compressive siab tab sis tsis tshua muaj zog tensile. Tau ntau xyoo lawm, steel mesh lossis reinforcing tuav tau siv los kov yeej qhov teeb meem no. Txawm li cas los xij, nrog kev nce qib hauv cov ntaub ntawv tshawb fawb, fiber reinforcement tau tshwm sim los ua ib qho kev ua tau zoo dua thiab muaj txiaj ntsig zoo dua, muab cov txiaj ntsig zoo tshaj plaws, tsis tshua muaj kev tawg, thiab tsim kom yooj yim dua.

Txheej txheem cej luam ntawm Carbon Fiber Reinforcement

Carbon fiber ntauCov pob zeb muaj zog yog tsim los ntawm carbonized polymer filaments, feem ntau muab los ntawm polyacrylonitrile (PAN). Los ntawm kev tswj cov cua sov thiab cov txheej txheem carbonization, cov polymer filaments tau hloov mus rau ultra- fibers muaj zog. Cov pa roj carbon fibers no tau sib cais nyob rau hauv cov cement matrix, tsim cov khoom sib xyaw uas txhim kho lub cev thiab lub zog ntawm cov pob zeb. Carbon fiber reinforced qhob boasts cov khoom siv zoo heev, dej-cov khoom tiv taus, thiab tsis kam mus rau qhov kub thiab txias hloov pauv, uas tsis pom muaj nyob rau hauv cov pa hluav taws xob ntxiv. Nws kuj nthuav tawm cov tshuaj lom neeg ruaj khov, ntev - siv lub zog ua haujlwm ntev, thiab qhov ruaj khov nyob rau hauv qhov chaw muaj alkaline heev.

Hloov cov hlau nrog carbon fiber tshem tawm qhov kev puas tsuaj thiab kev puas tsuaj ntawm cov pob zeb uas muaj zog los ntawm cov dej ntsev, txo qhov hnyav ntawm cov khoom siv hauv tsev, ua kom yooj yim rau kev txhim kho thiab kev tsim kho, thiab ua kom luv luv ntawm kev tsim kho. Cov pa roj carbon fiber kuj qhia txog kev co- damping zog, absorbing shocks thiab nce seismic tsis kam thiab flexural zog ntau tshaj kaum zaug. Carbon fiber reinforced pob zeb ua pov thawj muaj lub zog tensile siab, lub zog flexural, tawg tsis kam, thiab corrosion kuj. Vim nws cov coefficient tsawg ntawm kev nthuav dav, carbon fiber reinforced qhob nthuav tawm cov cua sov ua haujlwm zoo heev thiab qhov kub thiab txias deformation tsawg.

Lub luag haujlwm tseem ceeb ntawm carbon fiber reinforced pob zeb yog los tiv thaiv kev nthuav tawm ntawm microcracks hauv cov pob zeb thiab tiv thaiv qhov tshwm sim thiab kev loj hlob ntawm macrocracks. Yog li ntawd, nws lub zog tensile thiab shear, dabtsi yog khoov, thiab torsional zog, uas yog tswj los ntawm lub ntsiab tensile kev nyuaj siab, yog ho txhim khu kev qha; Nyob rau tib lub sijhawm, nws muaj lub siab matrix deformation tsis kam, yog li txhim kho nws tensile, khoov, thiab cuam tshuam toughness. Thaum cov pa roj carbon fiber ntau feem yog 1.18%, qhov sib cais tensile lub zog ntawm cov qauv nce 1.2%. Raws li txoj cai sib xyaw, qhov kev txhawb zog ntawm cov pa roj carbon fiber ntau yuav tsum nce ntxiv nrog kev nce ntawm fiber ntau hauv cov cement. Thaum qhov hnyav feem pua ​​​​ntawm carbon fiber tsawg dua 5%, qhov kev sib raug zoo no yuav luag linear. Thaum cov ntsiab lus nce ntxiv, cov pa roj carbon fiber ntau yog qhov nyuaj rau disperse tusyees hauv matrix, thiab cov nyhuv reinforcing tsis tuaj yeem ua tiav, thiab txawm tias lub zog tensile ntawm carbon fiber ntau yog txo. Tsis tas li ntawd, cov pa roj carbon fiber ntau kuj muaj qhov zoo corrosion kuj, permeability kuj, hnav tsis kam, shrinkage kuj, thiab kav ntev.

Txheej txheem cej luam ntawm iav Fiber Reinforcement

Cov iav fiber ntau reinforced pob zeb (GFRP) yog cov khoom siv sib xyaw ua ke los ntawm kev faib tawm siab -elasticity, alkali- cov iav fiber ntau hauv cov cement mortar lossis cov pob zeb zoo tib yam. Vim hais tias txoj kab uas hla ntawm cov iav fibers tsuas yog 5-20 μm, yuav luag zoo ib yam li cov cement particles, cement paste los yog nplua xuab zeb yog siv los ua cov ntaub ntawv thaum siv cov iav fibers, thiab coarse aggregates nrog qhov loj me me yuav luag tag nrho zam. Yog li ntawd, cov khoom sib xyaw ua los ntawm cov khoom siv no tseem hu ua cov cement reinforced.

Kev siv cov iav fiber reinforced pob zeb yog kev taw qhia yav tom ntej rau kev tsim kho engineering. Nws tsis tsuas yog kov yeej qhov tsis txaus ntawm cov khoom siv pob zeb zoo tib yam, xws li hnyav hnyav, tsis muaj zog tensile, thiab tsis zoo cuam tshuam, tab sis kuj muaj cov yam ntxwv tsis pom hauv cov pob zeb zoo tib yam. Cov iav fiber reinforced pob zeb cov khoom yog nyias thiab sib dua. Vim yog kev siv siab heev -tensile- lub zog iav fibers raws li kev txhawb nqa, nws lub zog tensile siab heev. Kev faib tawm ntawm cov iav fibers hauv cov pob zeb ua kom tsis txhob tawg ntawm cov khoom ua vaj tse. Vim tias nws tuaj yeem nqus tau ntau lub zog thaum tsis ua haujlwm, nws muaj kev cuam tshuam zoo heev thiab muaj zog flexural siab. Tsis tas li ntawd, iav fiber reinforced qhob cov khoom muaj cov khoom zoo demolding, yooj yim rau kev ua, thiab tuaj yeem ua tau yooj yim rau hauv ntau yam duab thiab cov khoom tsis zoo.
