Ua ib yam khoom tseem ceeb rau kev hnav tsis hnyavtshebhloov hlau nrog yas,Cov ntaub ntawv FRP / compositemuaj feem cuam tshuam nrog kev txuag hluav taws xob ntawm lub tsheb, kev tiv thaiv ib puag ncig thiab kev nyab xeeb. Kev siv cov yas / cov khoom sib xyaw ua los ntawm cov iav fiber los tsim cov plhaub tsheb thiab lwm yam khoom cuam tshuam yog ib txoj hauv kev zoo tshaj plaws los ua kom lub tsheb sib dua.
Txij li thaum lub tsheb FRP thawj zaug hauv ntiaj teb, GM Corvette, tau tsim tiav hauv xyoo 1953, cov ntaub ntawv FRP / composite tau dhau los ua lub zog tshiab hauv kev lag luam tsheb. Cov txheej txheem tso tes ib txwm tsuas yog tsim rau kev tsim khoom me me, thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev txhim kho tas mus li ntawm kev lag luam tsheb.
Pib txij li xyoo 1970, vim yog kev txhim kho zoo ntawmCov ntaub ntawv SMCthiab kev siv tshuab molding thiab cov txheej txheem hauv pwm, qhov kev loj hlob txhua xyoo ntawm FRP / cov ntaub ntawv sib xyaw hauv kev siv tsheb tau txog 25%, ua thawj zaug hauv kev txhim kho cov khoom lag luam FRP tsheb. Lub sijhawm ntawm kev txhim kho sai;
Los ntawm xyoo 1990s thaum ntxov ntawm xyoo 1920s, nrog rau qhov kev thov nce ntxiv rau kev tiv thaiv ib puag ncig, lub teeb yuag, thiab kev txuag hluav taws xob, cov ntaub ntawv thermoplastic composite sawv cev los ntawmGMT (iav fiber lev reinforced thermoplastic composite khoom) thiab LFT (ntev fiber reinforced thermoplastic composite khoom)tau txais. Nws tau tsim kho sai sai, thiab feem ntau yog siv rau hauv kev tsim cov khoom siv hauv tsheb, nrog rau kev loj hlob txhua xyoo ntawm 10-15%, teeb tsa lub sijhawm thib ob ntawm kev txhim kho sai. Raws li cov ntaub ntawv tshiab, cov ntaub ntawv sib xyaw maj mam hloov cov khoom hlau thiab lwm yam ntaub ntawv ib txwm muaj hauv cov khoom siv hauv tsheb, thiab tau ua tiav cov txiaj ntsig kev lag luam thiab kev nyab xeeb ntau dua.
FRP/composite auto parts feem ntau yog muab faib ua peb pawg:cov khoom ntawm lub cev, cov khoom ntawm cov qauv thiab cov khoom ua haujlwm.
1. Cov khoom ntawm lub cev:suav nrog lub cev plhaub, ru tsev tawv, sunroofs, qhov rooj, radiator grilles, headlight reflectors, pem hauv ntej thiab nram qab bumper, thiab lwm yam, nrog rau sab hauv. Qhov no yog qhov kev taw qhia tseem ceeb ntawm kev siv FRP / composite cov ntaub ntawv hauv tsheb, feem ntau yog kom tau raws li qhov xav tau ntawm kev tsim qauv streamlined thiab zoo nkauj. Tam sim no, lub peev xwm rau kev txhim kho thiab daim ntawv thov tseem loj heev. Feem ntau iav fiber reinforced thermosetting plastics. Cov txheej txheem molding ib txwm muaj xws li: SMC / BMC, RTM thiab tes lay-up / tsuag.
2. Cov khoom siv hauv paus:suav nrog cov brackets pem hauv ntej, bumper thav duab, rooj zaum thav duab, pem teb, thiab lwm yam. Lub hom phiaj yog txhawm rau txhim kho kev ywj pheej tsim, kev hloov pauv tau yooj yim thiab kev ncaj ncees ntawm cov khoom. Feem ntau siv cov khoom siv SMC, GMT, LFT thiab lwm yam khoom siv muaj zog.
3.Cov khoom ua haujlwm:Nws lub ntsiab lus tseem ceeb yog tias nws xav tau kev tiv taus kub thiab roj tsis kam, feem ntau yog rau lub cav thiab nws cov khoom nyob ib puag ncig. Xws li: lub hau valve cav, lub tshuab nqus manifold, lub lauj kaub roj, lub hau lim cua, lub hau chav iav, lub tshuab cua baffle, lub yeeb nkab nkag phaj, lub kiv cua hniav, lub nplhaib qhia cua kiv cua, lub hau cua sov, qhov chaw tank dej, lub plhaub qhov hluav taws xob, lub twj tso kua dej turbine, lub rooj tsavxwm rwb thaiv suab nrov ntawm lub cav, thiab lwm yam. Cov ntaub ntawv tseem ceeb ntawm cov txheej txheem yog: SMC / BMC, RTM, GMT thiab iav fiber reinforced nylon.
4. Lwm cov khoom cuam tshuam:xws li CNG lub tog raj kheej, lub tsheb thauj neeg thiab RV qhov chaw huv, qhov chaw maus taus, cov vaj huam sib luag tiv thaiv kev ci ntsa iab thiab cov ncej tiv thaiv kev sib tsoo, cov ncej cais kev loj, cov txee ru tsev tsheb tshuaj xyuas khoom, thiab lwm yam.
