Ntev Fiber Pellet yog dab tsi? Qhov txiaj ntsig ntawm LGF Composites
Ntev fiber ntau yas pellets yog ib hom ntawm cov khoom siv ntxiv dag zog ua los ntawm kev sib xyaw cov fibers ntev nrog cov thermoplastic resins.
Ntev Fiber Composites yog dab tsi?
Hauv kev tshawb fawb ntawm cov ntaub ntawv niaj hnub no, ntev - cov ntaub ntawv fiber ntau yog maj mam hloov cov qauv xaiv cov khoom hauv kev tsim khoom nrog lawv cov qauv zoo thiab kev ua tau zoo.
Cov khoom siv fiber ntau ntev xa mus rau siab -kev ua tau zoo fiber ntau- cov khoom sib txuas ua ke tsim los ntawm kev sib txuas cov fiber ntau ntev dua li cov tsoos luv luv - fiber ntau plastics (feem ntau ntau dua lossis sib npaug li 5 hli, thiab txawm txog li 50 hli) nrog cov thermoplastic lossis thermosetting resin matrices. Piv nrog luv- fiber ntau cov ntaub ntawv (fiber ntev <1 mm), ntev fibers tsim ib tug zoo dua load hloov network nyob rau hauv matrix, endowing cov khoom uas muaj zog dua, nruj, cuam tshuam thiab qaug zog kuj.
Cov yam ntxwv tseem ceeb ntawm cov khoom vaj khoom tsev
Tus nqi tseem ceeb ntawm qhov ntev - cov ntaub ntawv fiber ntau yog los ntawm lawv cov microstructure tshwj xeeb. Thaum qhov ntev ntawm fiber ntau tshaj qhov tseem ceeb (feem ntau ntau dua 5 hli), tus cwj pwm ntawm cov fiber ntau hauv matrix yuav raug hloov pauv zoo. Tsis zoo li qhov yooj yim "filling" nyhuv ntawm luv fibers, ntev fibers yog tsis tu ncua thiab tsis tu ncua nyob rau hauv lub matrix. Cov qauv no yuav ua rau muaj kev cuam tshuam loj heev thaum raug quab yuam. Tshwj xeeb, thaum microcracks tshwm sim hauv cov khoom siv, cov fibers ntev ntev hla ob sab ntawm cov kab nrib pleb tuaj yeem txuas ntxiv rau lub nra thiab tiv thaiv kom tsis txhob tawg. Cov txheej txheem no ua rau muaj kev cuam tshuam qhov hnyav ntawm cov khoom kom ncav cuag ntau zaus ntawm luv luv - fiber ntau sib xyaw, thiab nws ua tau zoo tshwj xeeb hauv cov ntawv thov xws li tsheb thauj khoom uas xav tau kev nqus ntawm lub zog.
Daim ntawv thov Ntau yam ntawm cov khoom siv fiber ntau ntev
Automotive qhov chaw
Cov khoom sib xyaw ua ke, chassis plhaub, roj teeb pob plhaub
Nruas tshuab ntxhua khaub ncaws, cua txias kiv cua impeller
Qhov txawv qhov zoo ntawm kev ua lag luam kev sib tw
Nyob rau hauv lub ntsej muag ntawm kev sib tw los ntawm cov khoom siv ib txwm muaj, ntev - cov ntaub ntawv fiber ntau tau tsim cov kev cuam tshuam tsis zoo hauv ntau qhov ntev. Nyob rau hauv cov nqe lus ntawm lub teeb yuag, nws qhov zoo yog tsis tsuas yog xav txog nyob rau hauv cov ntaub ntawv zoo li qub qhov hnyav, tab sis kuj nyob rau hauv lub dynamic system - theem kev pab cuam. Cov tuam txhab hluav taws xob tshiab tuaj yeem siv cov ntaub ntawv sib xyaw ua ke ntev carbon fiber ntau los ua cov roj teeb pob casings, uas tuaj yeem txo qhov hnyav thiab ua tiav cov txiaj ntsig ntawm kev siv hluav taws xob tsawg. Lub kaw lus tau yooj yim dua thaum lub roj teeb lub neej tau txhim kho.
Tus nqi - qhov txiaj ntsig piv yog lwm qhov kev ua tiav. Txawm hais tias tus nqi ntawm cov khoom siv ntev ntev - cov khoom siv fiber ntau tuaj yeem siab dua li cov hlau zoo tib yam, lawv cov nqi tag nrho lub neej muaj txiaj ntsig zoo. Siv lub thawv cia ntawm cov tsheb lag luam ua piv txwv. Lub cev steel lub cev yuav tsum tau mus los ntawm ntau yam txheej txheem xws li stamping, vuam thiab tiv thaiv - xeb kev kho mob, thaum lub thawv lub cev tsim los ntawm LGF-PP compound resin nyob rau hauv ib daim tsuas yog yuav tsum tau peb txheej txheem, txo cov peev txheej pwm thiab txo cov khoom siv hluav taws xob. Qhov tseem ceeb tshaj plaws, piv nrog cov thawv steel, cov thawv ntim khoom sib xyaw yuav tsum muaj kev tiv thaiv kev tiv thaiv tsawg dua -corrosion, thiab tag nrho cov nqi qis dua.
Hauv qhov loj me ntawm kev txhim kho kom ruaj khov, ntev - cov ntaub ntawv fiber ntau ua kom pom kev hloov tau zoo dua rau Lub Sijhawm. Nyob rau hauv sib piv, qhov tsis yog -recallability ntawm thermosetting composites yog txawm tsawg haum rau kev loj hlob ntawm niaj hnub kev sib raug zoo ib puag ncig thiab cov kev xav tau ntawm cov cai.
Dab tsi yog qhov zoo ntawm cov khoom siv fiber ntau ntev?
1. Kev ua haujlwm siab txhua yam
2. Siab zog, siab toughness, siab rigidity
3. Corrosion kuj thiab tshuaj tiv thaiv
4. Kev tiv thaiv siab
5. Kub thiab kub tsis kam
6. Kev qaug zog thiab hnav tsis kam
Lub evolution ntawm mainstream khoom systems
Qhov ntev - cov khoom siv fiber ntau tam sim no muaj nyob hauv kev ua lag luam tau tsim los ua ntau yam sib txawv. iav fiber reinforced systems thiab carbon fiber reinforced systems yog ob hom ntau tshaj. Ob leeg muaj irreplaceable txoj hauj lwm nyob rau hauv ntau yam structural Cheebtsam vim lawv tus kheej zoo.
Saib mus rau yav tom ntej, ntev - cov ntaub ntawv fiber ntau yog tsim los ntawm kev sib koom ua ke thiab kev tsim khoom ntse. Nyob rau yav tom ntej, cov khoom siv no yuav ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nrog rau kev nce qib ntawm kev siv thev naus laus zis tas li, nws tus nqi yuav pheej yig dua, thiab nws daim ntawv thov yuav dhau los ua ntau dua. Nws tuaj yeem hais tau tias cov khoom siv no, uas yog ob qho tib si sib sib zog nqus thiab ruaj khov, ua rau muaj kev hloov pauv hauv kev tsim khoom.
