Vim li cas fiberglass tau dhau los ua cov khoom siv tshiab rau kev txhim kho hauv ntau qhov chaw?
No.1 Performance Advantages
Fiberglass, txawm tias nws lub npe yuav zoo li tsis zoo, yog qhov tseem ceeb ntawm cov khoom siv sib xyaw. Nws yog tsim los ntawm silicon dioxide thiab lwm yam khoom siv raw los ntawm kev kub siab -kub yaj- txheej txheem kos duab. Raws li cov khoom siv hauv iav, nws tuaj yeem muab faib ua alkali- iav fiber ntau (E iav fiber), nruab nrab -alkali iav fiber (C iav fiber), thiab lwm yam; Raws li txoj kab uas hla ntawm ib qho filament, nws tau muab faib ua coarse fiber ntau thiab siab -qib fiber ntau.
Fiberglass boasts qhov zoo ntawm kev ua tau zoo. Nws ultra- lub zog tshwj xeeb ua rau nws sib nrug, nrog lub zog tensile ncav cuag 1000-3000 MPa, thaum nws qhov ceev tsuas yog 1/4 ntawm cov hlau, ua tiav "lub teeb yuag thiab siab zog." Nyob rau hauv cov nqe lus ntawm huab cua tsis kam, iav fiber ntau tuaj yeem tiv thaiv corrosion los ntawm acids, alkalis, thiab lwm yam tshuaj, thiab tuaj yeem tiv taus qhov kub thiab txias ntawm 300 degrees Celsius, ua kom muaj kev ruaj ntseg txawm tias nyob hauv qhov chaw ntub thiab kub. Ib txoj kev tshawb fawb luam tawm xyoo 2022 los ntawm Wu Rui li al. qhia tau hais tias thaum lub sij hawm interlaminar shear lub zog ntawm iav fiber reinforced polymer (GFRP) txo los ntawm li 20% nyob rau hauv ib tug ntub thiab kub ib puag ncig ntawm 60 degree, nws muaj peev xwm ib feem rov qab tom qab ziab. Interfacial debonding yog lub ntsiab tsis ua hauj lwm mechanism, tab sis tag nrho, nws tseem pom zoo ib puag ncig adaptability. Los ntawm kev ua tiav, iav fiber ntau tuaj yeem ua tau zoo nrog ob qho tib si thermoplastics (xws li PP thiab PA) thiab thermosetting epoxy resins. Los ntawm kev kho tus neeg sawv cev sib txuas, kev sib txuas ntawm kev sib txuas nrog lub matrix tuaj yeem txhim kho ntxiv, muab ntau txoj hauv kev rau kev sib xyaw molding.
Tsis yog . 2 Daim ntawv thov toj roob hauv pes
Fiberglass, nrog rau nws qhov kev ua tau zoo, tau nthuav dav nws mus txog ntau yam. Hauv kev lag luam tsheb, nws yog lub zog loj hauv kev sib sib zog nqus, dav siv hauv lub cev, ua tiav qhov hnyav ntawm 15%-20%, txo kev siv hluav taws xob thaum txhim kho kev ua haujlwm. Cheebtsam xws li lub cav hoods siv iav fiber reinforced composites, ua tau raws li siab -kub kuj yuav tsum tau thiab muaj zoo heev corrosion kuj. Hauv thaj chaw aerospace, fiberglass kuj muaj qhov chaw. Helicopter rotors siv fiberglass es tsis txhob carbon fiber, muab cov nqi zoo heev. Fiberglass kuj tseem siv rau hauv cov khoom siv sab hauv, kom muaj zog thaum txo qhov hnyav thiab txo cov nqi khiav lag luam. Nyob rau hauv lub neej txhua hnub, fiberglass yog ubiquitous. Nuv ntses pas nrig thiab ntaus golf hauv cov khoom siv kis las tau txais txiaj ntsig los ntawm nws lub zog siab thiab tawv tawv, muab kev paub zoo rau cov neeg siv khoom. Fiberglass reinforced cov ntaub ntawv yog siv nyob rau hauv lub casings ntawm cov khoom siv hauv tsev, ua kom tiav qhov sib npaug ntawm lub zog siab thiab tus nqi qis, ua rau ob qho tib si zoo nkauj thiab ruaj khov.
Tsis muaj . 3 Kev tsis txaus thiab kev tawg
Tau kawg, fiberglass tsis yog tsis muaj nws qhov tsis zoo. Nws yog ib qho nkig, nrog rau kev tawg ntawm tsuas yog 3% -4%, ua rau nws yooj yim tawg nyob rau hauv kev cuam tshuam loj. Tsis tas li ntawd, nws cov khoom hluav taws xob txwv nws daim ntawv thov hauv kev sib txuas lus siab. Txawm li cas los xij, cov kws tshawb fawb tau daws cov teeb meem no. Los ntawm txheej txheej nrog cov khoom sib txuas xws li silanes, tus choj muaj zog tuaj yeem tsim los ntawm fiberglass thiab matrix, feem ntau txhim kho kev sib raug zoo ntawm lub ntsej muag thiab txhim kho cov tawv tawv ntawm cov khoom sib xyaw. Fiberglass kuj tuaj yeem sib xyaw nrog aramid fibers, ntxiv rau ib leeg qhov zoo thiab txhim kho cov khoom siv cuam tshuam, yog li nthuav nws thaj tsam daim ntawv thov.
