一, Dab tsi yog cov qauv iav fiber ntau, koj puas paub?
Tam sim no, iav fiber ntau tau siv dav.Cov iav fiber ntau yuav txais cov ntaub ntawv sib txawv raws li cov khoom sib txawv, cov txheej txheem thiab kev ua haujlwm ntawm kev siv, kom ua tau raws li kev siv sib txawv.Dab tsi yog cov qauv sib txawvfiberglass sib xyaw?
1. Twistless Roving
Untwisted roving ntxiv muab faib uancaj qhaiav fiber roving cov ntaub ntawv thiab plied untwisted roving.Direct yarn yog ib qho fiber ntau txuas ncaj qha los ntawm iav yaj, tseem hu ua ib leeg-strand untwisted roving.Cov xov paj plied yog cov xuab zeb ntxhib ua los ntawm ntau qhov sib npaug sib npaug, uas tsuas yog kev sib txuas ntawm ntau cov xov paj ncaj qha.
Qhia rau koj me ntsis ua kom yuam kev, yuav ua li cas kom paub qhov txawv ntawm cov xov paj ncaj ncaj thiab cov xov paj ntaub?Ib strand ntawm xov paj yog kos tawm thiab co sai sai.Ib qho uas tseem tshuav yog cov xov paj ncaj, thiab ib qho uas tau tawg mus rau hauv ntau cov strands yog cov xov paj.
2. Tej xov paj
Bulked yarn yog tsim los ntawm kev cuam tshuam thiab cuam tshuam cov iav fibers nrog compressed cua kom cais cov fibers hauv lubiav fiber ntau thiab nce lub ntim, thiaj li hais tias nws muaj ob lub siab zog ntawm nruam fibers thiab bulkiness ntawmchopped fiberglass.
3. Plaid
Plaid yogfiberglass weave daim ntaub.Lub warp thiab weft yog interlaced ntawm 90 ° nce thiab nqis, tseem hu ua ntaub woven.Lub zog ntawm gingham feem ntau yog nyob rau hauv warp thiab weft cov lus qhia.
4. Multiaxial Npuag
Fiberglass Multiaxial Fabric yog tsim los ntawm weaving iav fiber ncaj qha yam tsis muaj twisting roving ntawm lub tshuab multi-axial braiding.
Lub kaum sab xis ntau dua yog 0 °, 90 °, 45 °, -45 °, uas tau muab faib ua unidirectional daim ntaub, biaxial daim ntaub, triaxial daim ntaub thiab quadriaxial daim ntaub raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg.
5. iav fiber ntau lev
Gfiber ntau matt yog sib sau ua ke hu ua "xav", ib daim ntawv zoo li cov khoom ua los ntawm cov hlua txuas ntxiv los yog cov hlua khi uas tsis tau taw qhia los ntawm cov tshuaj binders lossis kev ua haujlwm txhua yam.Felts tau muab faib ntxiv rau hauvchopped strand mats, stitched mats, composite mats, nruam mats, deg mats, thiab lwm yam. Cov ntaub ntawv tseem ceeb: pultrusion, winding, molding, RTM, nqus introduction, GMT, thiab lwm yam.
6.Ar iav fiber ntau tws strands
Cov xov paj fiberglass yog chopped rau hauv cov strands ntawm ib qho ntev.Cov ntawv thov tseem ceeb: ntub dej (txhim kho gypsum, ntub dej nyias), BMC, thiab lwm yam.
二 、 yam dab tsi yuav cuam tshuam rau lub zog tensile ntawm iav fiber ntau
Qhov tshwm sim ntawm ntab iav tshuab tuaj yeem hais tau los muab kev txhawb zog rau cov iav sib sib zog nqus ua, thiab raws li kev taw qhia ntawm cov txheej txheem tshiab no, hom iav sib sib zog nqus ua tau ntau dua, ntawm cov uas.iav fiber ntau epoxy compositebelongs rau ntau iav sib sib zog nqus ua.Ib qho ntawm cov pawg, thiab cov iav fiber ntau tau siv dav hauv ntau qhov kev lag luam thiab kev lag luam hauv lub neej niaj hnub txij li nws txoj kev tshawb fawb thiab kev loj hlob.Yog li dab tsi yuav cuam tshuam rau lub zog tensile ntawm iav fiber ntau nrog kev pabcuam zoo thiab lub zog?
Thawj qhov tseem ceeb, txoj kab uas hla ntawm fiber ntau thiab qhov kub thiab txias ntawm ib puag ncig uas nws siv.
Nyob rau hauv cov nqe lus ntawm cov tsos, iav fiber ntau tsis zoo li txawv txawv ntawm cov xov paj zoo tib yam, tab sis daim ntawv thov ntau yam ntawm cov iav fiber ntau yog dav dua li cov xov paj ntaub.Txawm li cas los xij, lub zog tensile yuav muaj qee yam cuam tshuam rau kev siv cov nyhuv thiab tag nrho cov kev pab cuam lub neej ntawm cov khoom no.cuam tshuam.Txawm li cas los xij, muaj ntau yam uas yuav cuam tshuam rau lub zog tensile ntawm iav fibers, nrog rau txoj kab uas hla ntawm fiber ntau nws tus kheej thiab qhov kub ntawm ib puag ncig uas siv cov khoom siv tom qab.Feem ntau, lub thinner lub fiber txoj kab uas hla yog nyob rau ntawm ib tug muab kub.Qhov siab dua lub zog tensile.
Qhov thib ob, kev kho deg siv
Cov iav fiber ntau yog tsim los ntawm kev siv iav los ua cov khoom siv sib sib zog nqus, thiab cov txheej txheem tshwj xeeb yuav tsum muaj nyob rau hauv tag nrho cov txheej txheem tsim kom paub qhov kev hloov ntawm iav mus rau fiber ntau.Ntawm lawv, txoj kev kho tshuaj thiab txoj hauv kev tsiv teb tsaws yog rau txoj kev kho saum npoo.ib cov.Yog tias txoj kev kho tshuaj siv tau thaum lub sijhawm tsim khoom, lub zog tensile yuav txo qis tom qab tus neeg sawv cev sizing raug tshem tawm los ntawm kev kho cua sov, tab sis lub zog tensile ntawmfiberglass rwb thaiv tsev cov ntaub ntawvyuav rov qab mus rau lub xeev qub tom qab siv cov nplaum nplaum hauv nruab nrab.
Cov ntsiab lus saum toj no yog kev soj ntsuam ntawm cov xwm txheej uas cuam tshuam rau lub zog tensile ntawm iav fiber.Nws tuaj yeem pom tias txoj kab uas hla ntawm fiber ntau nws tus kheej thiab qhov kub thiab txias ntawm qhov chaw siv tom qab yuav cuam tshuam rau lub zog tensile ntawm iav fiber ntau nrog kev pabcuam zoo thiab tus nqi qis.Tsis tas li ntawd, txheej txheej txheej txheej txheej siv los ntawm cov iav fiber ntau yuav cuam tshuam rau nws lub zog tensile.
