Raws li ib qho tseem ceeb lub teeb yuag khoom rautshebhloov steel nrog yas,FRP / cov ntaub ntawv sib xyawmuaj kev sib raug zoo nrog lub tsheb txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev nyab xeeb.Kev siv cov iav fiber reinforced plastics / cov ntaub ntawv sib xyaw los tsim lub tsheb lub cev lub cev thiab lwm yam muaj feem xyuam yog ib txoj hauv kev zoo tshaj plaws los ua kom lub tsheb sib tw.
Txij li thaum lub ntiaj teb thawj lub tsheb FRP, GM Corvette, tau ua tiav hauv xyoo 1953, FRP / cov ntaub ntawv sib xyaw tau dhau los ua lub zog tshiab hauv kev lag luam tsheb.Cov txheej txheem kev ua haujlwm ntawm tes yog tsuas yog tsim nyog rau kev tsim khoom me me, thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev txhim kho txuas ntxiv ntawm kev lag luam tsheb.
Pib xyoo 1970, vim muaj kev vam meej ntawm txoj kev loj hlobSMC cov ntaub ntawvthiab kev siv tshuab moulding tshuab thiab hauv-pwm txheej thev naus laus zis, kev loj hlob txhua xyoo ntawm FRP / cov ntaub ntawv sib xyaw hauv kev siv tsheb mus txog 25%, dhau los ua thawj hauv kev tsim cov khoom siv tsheb FRP.Lub sijhawm ntawm kev loj hlob sai;
Los ntawm thaum ntxov 1990s ntawm lub xyoo 1920s, nrog rau kev xav tau ntau ntxiv rau kev tiv thaiv ib puag ncig, lub teeb yuag, thiab kev txuag hluav taws xob, cov khoom siv thermoplastic puas sawv cev los ntawmGMT (iav fiber ntau mat reinforced thermoplastic composite khoom) thiab LFT (ntev fiber reinforced thermoplastic composite khoom)tau txais.Nws tau tsim sai heev, thiab feem ntau yog siv rau hauv kev tsim cov khoom siv hauv tsheb, nrog kev loj hlob txhua xyoo ntawm 10-15%, teeb tsa lub sijhawm thib ob ntawm kev loj hlob sai.Raws li qhov ua ntej ntawm cov ntaub ntawv tshiab, cov ntaub ntawv sib xyaw yog maj mam hloov cov khoom siv hlau thiab lwm yam khoom siv hauv cov khoom siv tsheb, thiab tau ua tiav kev lag luam thiab kev nyab xeeb.
FRP / composite qhov chaw pib feem ntau muab faib ua peb pawg:lub cev qhov chaw, qhov chaw ua haujlwm thiab qhov chaw ua haujlwm.
1. Lub cev qhov chaw:nrog rau lub cev plhaub, lub ru tsev nyuaj, lub hnub ci, qhov rooj, radiator grilles, headlight reflectors, pem hauv ntej thiab rear bumpers, thiab lwm yam, nrog rau cov khoom sab hauv.Qhov no yog lub ntsiab lus tseem ceeb ntawm daim ntawv thov ntawm FRP / cov ntaub ntawv sib xyaw hauv tsheb, feem ntau ua kom tau raws li cov kev xav tau ntawm kev tsim kho kom zoo thiab zoo nkauj zoo nkauj.Tam sim no, lub peev xwm rau kev txhim kho thiab kev siv yog tseem loj heev.Feem ntau yog iav fiber reinforced thermosetting yas.Cov txheej txheem molding muaj xws li: SMC / BMC, RTM thiab tes lay-up / tshuaj tsuag.
2. Cov khoom siv:nrog rau pem hauv ntej-kawg brackets, bumper thav duab, lub rooj thav duab, pem teb, thiab lwm yam. Lub hom phiaj yog los txhim kho txoj kev ywj pheej tsim, versatility thiab kev ncaj ncees ntawm cov khoom.Feem ntau siv lub zog siab SMC, GMT, LFT thiab lwm yam ntaub ntawv.
3.Functional qhov chaw:Nws lub ntsiab feature yog tias nws yuav tsum tau kub tsis kam thiab roj corrosion kuj, feem ntau yog rau lub cav thiab nws cov nyob ib puag ncig.Xws li: cav valve cover, intake manifold, roj lauj kaub, cua lim cover, iav chamber cover, cua baffle, intake yeeb nkab guard phaj, kiv cua hniav, kiv cua cua qhia nplhaib, rhaub cover, dej tank qhov chaw, Outlet plhaub, dej twj tso kua mis turbine , cav suab rwb thaiv tsev board, thiab lwm yam. Cov txheej txheem tseem ceeb ntawm cov ntaub ntawv yog: SMC / BMC, RTM, GMT thiab iav fiber reinforced nylon.
4. Lwm yam ntsig txog:xws li CNG thooj voos kheej kheej, neeg nrog caij tsheb thiab RV huv qhov chaw, maus taus qhov chaw, txoj kev loj los tiv thaiv glare panels thiab tiv thaiv pillars, txoj kev loj cais piers, cov khoom soj ntsuam tsheb ru tsev txee, thiab lwm yam.
