Fiberglass reinforced yas, tseem hu ua fiberglass reinforced yas. Nws yog cov khoom siv sib xyaw uas siv cov iav fiber ntau thiab nws cov khoom (fiberglass daim ntaub, daim kab xev, muaj kev xav, xov paj, thiab lwm yam) raws li cov ntaub ntawv txhawb zog thiab cov khoom siv hluavtaws ua cov khoom siv matrix. Lub tswv yim ntawm cov ntaub ntawv sib xyaw yog hais txog cov khoom siv uas tsis tuaj yeem ua tau raws li cov kev xav tau ntawm kev siv thiab yuav tsum muaj ob lossis ntau cov ntaub ntawv sib xyaw ua ke los ua lwm yam khoom siv uas tuaj yeem ua tau raws li cov neeg xav tau, xws li cov ntaub ntawv sib xyaw.
Piv txwv li, txawm hais tias ib hom iav fiber ntau muaj lub zog siab, cov fibers yog xoob thiab tuaj yeem tiv taus qhov nro, khoov, shear, thiab compressive stressive. Nws kuj yog ib qho nyuaj rau tsim ib qho duab geometric ruaj khov thiab yog cov khoom siv xoob xoob. Vim nws lub zog sib npaug ntawm cov hlau thiab muaj cov khoom siv iav, nws kuj muaj cov xim tib yam, zoo li, corrosion kuj, hluav taws xob rwb thaiv tsev, thermal rwb thaiv tsev thiab lwm yam khoom xws li iav. Zoo li iav, nws tau tsim no yooj yim to taub lub npe "fiberglass". Los ntawm qhov no, nws tuaj yeem pom tias lub ntsiab lus ntawm fiberglass yog hais txog cov iav fibers, uas yog siv los ua cov ntaub ntawv txhawb zog thiab cov khoom siv hluavtaws ua cov ntaub ntawv hauv cov khoom siv ntxiv dag zog. Nws yog hu ua fiberglass reinforced plastics txawv teb chaws.
Cov khoom siv SMC yog cov ntawv luv rau Sheet molding compound, uas txhais tau tias yog daim ntawv molded yas hauv Suav. Cov ntaub ntawv tseem ceeb yog tsim los ntawm SMC cov xov paj tshwj xeeb, cov khoom siv tsis zoo, cov khoom siv qis qis, cov khoom ntim, thiab ntau yam khoom ntxiv. Nws yog ib hom resin raws li cov khoom siv sib xyaw. Thaum xyoo 1980s, Tuam Tshoj tau tshaj tawm cov khoom siv SMC siab heev thiab cov txheej txheem los ntawm txawv teb chaws.
SMC cov ntaub ntawv muaj kev ua tau zoo ntawm hluav taws xob, kev tiv thaiv corrosion, lub teeb yuag, yooj yim thiab hloov tau yooj yim engineering tsim, thiab lawv cov khoom siv kho tshuab tuaj yeem piv rau qee cov ntaub ntawv hlau. Yog li ntawd, lawv tau siv dav hauv tsheb thauj mus los, kev tsim kho, hluav taws xob / hluav taws xob thiab lwm yam lag luam. Cov khoom siv SMC yog ib hom fiberglass, uas npog ntau qhov loj dua li cov khoom siv SMC.
