Nrog kev nthuav dav txuas ntxiv ntawm daim ntawv thov kev lag luam, thermosetting cob qhia maj mam qhia lawv tus kheej cov kev txwv siab yuav tsum muaj nyob rau hauv cov kev txwv ntawm kev coj tsis kam thiab kub siab. Hauv qhov no, cov xwm txheej ntawm Thermoplastic Resin raws cov roj carbon fiber ntau yog maj mam nce, ua ib lub zog tshiab ntawm kev sib xyaw ua ke. Nyob rau hauv xyoo tsis ntev los no, Suav carbon fiber ntau thev naus laus zis tau ua rau kev txhim kho nrawm nrawm, thiab cov ntaub ntawv sib xyaw ntawm Thermopicish fiber ntau kuj tau nce ntxiv.
Hauv kev tshawb nrhiav ntawm cov fiber carbon fiber txhawb Thermoplastic Pre preg, peb txoj kev thov ntawm cov flopopicastic carbon fiber yog doedly
1. Los ntawm hmoov carbon fiber txhawb kom rov qab cov fiber fiber cuam txhawb nqa
Carbon Fiber thermopicastic composites tuaj yeem faib ua hmoov carbon fiber, unidirectional chacter carbon fiber thiab npuag carbon fiber ntau ntxiv. Qhov ntev dua cov fiber ntau dua yog, lub zog ntau yog muab los ntawm kev thov thauj khoom, thiab ntau dua cov zog tag nrho ntawm cov composite. Yog li ntawd, piv nrog hmoov los yog tws carbon fiber txhawb cov roj tov, txuas ntxiv carbon fermoplastic ntau cov composites muaj kev ua tau zoo dua. Cov feem ntau dav siv kev txhaj tshuaj molding txheej txheem hauv Suav teb yog hmoov los yog txhoov fiber fiber txhawb. Cov khoom lag luam muaj qee qhov kev txwv. Thaum txuas ntxiv cov fiber roj fiber txhawb tau siv, thermopictic carbon fiber ntau composites yuav usher nyob rau hauv ib qho chaw thov koj tam sim no.
2. Kev loj hlob los ntawm tsawg thermoplastic resin rau nruab nrab thiab siab kawg thermoplastic resin matrix
Thermoplastic Resin Matrix qhia cov ntaub ntawv fiber ntau, uas yog qhov nyuaj rau kev ua tsis tau zoo rau cov kev ua tau zoo ntawm kev ua kom tiav. Txhawm rau txhawm rau txhim kho lub wettability, cov composite kev hloov kho tshuab thev naus laus zis tau txais, thiab cov cuab yeej siv Resin extrusion tau txhim kho. Thaum txuas txog qhov dav ntawm carbon fiber strand, kev extrusion actusion tus nqi ntawm Resin tau nce. Lub wettability ntawm thermoplastic resin rau carbon fiber ntau tau txhim kho, thiab kev ua tau zoo ntawm carbon fiber ntau ntxiv dag zog ua ntej tau txais txiaj ntsig zoo. Lub resin matrix ntawm nruam carbon fiber thermopicastic composites tau ntse ntxiv los ntawm PPS thiab PA rau PI thiab PEEK.
3. Los ntawm kev sim xuas tes ua ke kom ruaj khov ntau lawm
Los ntawm kev ua tiav ntawm cov kev sim me me hauv chav kuaj kom ruaj khov hauv lub rooj sib tham, tus yuam sij yog tus tsim thiab kev hloov kho cov khoom siv ntau lawm. Seb cov file fiber ntau txhawb cov kev siv hluav taws xob thermoplastic tuaj yeem ua tiav cov ntsiab lus txhua hnub, tab sis kuj yog cov ntaub ntawv pov tseg hauv cov lus qhia txhua hnub, tab sis kuj yog tswj hwm thiab kev faib ua feem yog tsim nyog, txawm yog Cov pa roj carbon fiber nyob rau hauv precreg yog fortibuted thiab meej infiltrated, thiab seb qhov loj me thiab qhov loj me yog qhov tseeb.
