High Toughness CF PP Polymer

High Toughness CF Carbon Fiber PP Polymer

LCF PP khoom sawv cev rau Ntev Carbon Fiber reinforced Polypropylene.

LCF PP (Long Carbon Fiber Reinforced Polypropylene) yog ib ceg tseem ceeb hauv thaj tsam ntawm siab -kev ua tau zoo thermoplastic composites (LFRT - Ntev Fiber Reinforced Thermoplastics). Nws yog cov khoom siv sib xyaw ua los ntawm polypropylene (PP) resin, nrog cov roj carbon fiber ntau txuas ntxiv (Carbon Fiber, CF) ntawm qhov ntev ntau dua 5 millimeters ua haujlwm txhawb nqa. Nws yog tsim los ntawm cov txheej txheem tshwj xeeb xws li pultrusion impregnation. Qhov tshwm sim ntawm cov khoom siv no tsis yog tsuas yog kev sib xyaw ntawm ob cov ntaub ntawv; es, dhau los ntawm "ntev fiber ntau" thev naus laus zis, nws qhov kev ua tau zoo tau txhim kho, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv lub teeb yuag thiab siab - lub zog ntawm cov qauv siv. Nws plays lub luag haujlwm tseem ceeb hauv cov txheej txheem "hloov hlau nrog yas" thiab.

Lub hauv paus ntawm LCF PP: Ntev Fiber Reinforcement

Qhov tseem ceeb ntawm kev ua tau zoo sib txawv ntawm LCF PP composite thiab tsoos luv fiber reinforced PP (SCF) qia los ntawm nws qhov tshwj xeeb microstructure.
Short fibers (SCF):Qhov ntev fiber ntau feem ntau yog tsawg dua 1 millimeter thiab yog dispersed nyob rau hauv lub matrix thaum txhaj molding, feem ntau yog ua ib tug muab tub lim thiab muab ib tug me ntsis ntxiv zog, tab sis tsis muaj peev xwm tsim ib tug zoo kev nyuaj siab hloov network.
Ntev fibers (LCF):Qhov ntev fiber ntau yog raws li qhov kawg particle ntev (xws li 12 hli lossis 25 hli). Thaum lub sij hawm txhaj tshuaj molding, cov fibers ntev yuav intertwine thiab sib tshooj nrog ib leeg, tsim ib tug peb -dimensional, nruam "fiber skeletal network" nyob rau hauv lub tivthaiv.

Thaum cov khoom raug cuam tshuam rau sab nraud quab yuam lossis kev thauj khoom, lub cev pob txha no tuaj yeem hloov pauv thiab faib cov kev ntxhov siab, tiv thaiv kev ntxhov siab los ntawm kev xav ntawm ib qho taw tes thiab ua rau cov khoom tsis ua haujlwm. Lub matrix resin (PP) yog lub luag haujlwm rau encapsulating cov fibers, shaping lawv, thiab muab tshuaj tiv thaiv.

Qhov tseem ceeb ntawm kev ua tau zoo ntawm LCF PP Khoom

Kev taw qhia txog cov roj carbon fibers ntev tau txhim kho qhov kev ua haujlwm tsis zoo ntawm PP matrix, ua kom nws muaj cov yam ntxwv zoo sib xws rau cov khoom siv hluav taws xob thiab cov hlau.

1. Cov khoom siv zoo heev

Lub zog tshwj xeeb thiab siab tshwj xeeb modulus: Qhov no yog qhov zoo tshaj plaws ntawm LCF PP. Cov pa roj carbon fibers lawv tus kheej muaj lub zog siab heev thiab cov qauv, deb tshaj cov iav fibers. Compared to metals, LCF PP has an extremely low density, allowing the weight of components to be significantly reduced while maintaining the same rigidity or strength.
Kev cuam tshuam zoo heev: Thaum raug siab - kev cuam tshuam ceev, qhov ntev fiber ntau nqus lub zog los ntawm cov txheej txheem ntawm cov fibers. Qhov no txhais tau hais tias cov fibers yuav tshem tawm ntawm lub matrix ua ntej tawg, thiab cov txheej txheem no siv ntau lub zog cuam tshuam, ua rau cov khoom muaj zog heev, tshwj xeeb tshaj yog nyob rau hauv qis - qhov kub thiab txias qhov chaw uas tus qauv PP ua tsis zoo.
Zoo heev creep kuj: Creep yog hais txog qeeb yas deformation ntawm cov ntaub ntawv nyob rau hauv tas li kev nyuaj siab (tshwj xeeb tshaj yog nyob rau hauv high kub). Cov txheej txheem fiber ntau hauv LCF PP tuaj yeem tiv taus qhov deformation nyob rau hauv qhov ntev - lub sijhawm thauj khoom, ua rau nws tsim nyog rau cov khoom siv uas yuav tsum tau tswj xyuas qhov tseeb ntawm lub sijhawm ntev, xws li kev txhawb nqa thiab thav duab.

2. Optimized thermal kev ua tau zoo

High kub distortion kub (HDT): Lub HDT ntawm LCF PP yog ho ntau dua li ntawm unmodified PP thiab LGF PP. Qhov no qhia tau hais tias nws muaj peev xwm tswj tau nws cov txheej txheem rigidity ntawm qhov kub thiab txias (xws li nyob rau hauv lub engine compartment ntawm lub tsheb), yog li nthuav nws daim ntawv thov.
Tsis tshua muaj siab linear thermal expansion coefficient (CLTE): Qhov no yog ib qho tseem ceeb engineering yam ntxwv ntawm LCF PP. Nws CLTE tsawg heev thiab nyob ze rau cov hlau.
Dimensional stability: Nyob rau hauv huab cua hloov pauv (xws li lub caij txias thiab kub), lub warpage deformation ntawm lub Cheebtsam yog tsawg, kom ntseeg tau tias lub rooj sib txoos raug.

3. Khaws cov txiaj ntsig zoo ntawm PP matrix

Cov tshuaj tiv thaiv zoo heev: LCF PP tau txais txiaj ntsig zoo heev ntawm PP matrix rau ntau yam tshuaj, acids, hauv paus, ntsev, thiab cov kua hauv tsheb.
Kev nqus dej tsawg: PP yog cov khoom tsis yog -polar nrog cov dej nqus dej tsawg heev. Qhov no ua rau LCF PP Cheebtsam nthuav tawm cov cuab yeej zoo dua qub thiab qhov ruaj khov ntawm qhov chaw ntub dej piv rau cov nylon (PA)-raws li cov ntaub ntawv sib xyaw.

CF PP: Cov ntawv thov ib txwm

LCF PP yas pellet, nrog nws lub teeb yuag, siab - lub zog thiab cov khoom siv hluav taws xob, tau hloov pauv sai sai ntawm cov hlau thiab lwm yam yas yas hauv ntau qhov chaw tsim khoom siab - kawg:

Automotive Kev Lag Luam:
Cov Txheej Txheem Txheej Txheem: Dashboard (IP) thav duab, pem hauv ntej module (FEM) bracket, roj teeb (tshwj xeeb tshaj yog EV roj teeb pob) tais thiab tus neeg saib xyuas phaj, lub rooj zaum ncej, tsheb tailgate (lift gate) puab vaj huam sib luag, pedal sib dhos.
Engine Surroundings: Ntxuam hniav thiab ncej (ntiv nplhaib), cav hood cover.
Cov Khoom Siv Ua Haujlwm: Cov khoom siv hluav taws xob ua hluav taws xob, ECU (Electronic Control Unit) vaj tse xav tau EMI tiv thaiv.
Kev lag luam thiab Machinery:
Kev tuav dej: Siv los ua lwm yam rau cov hlau tsis muaj steel lossis cam khwb cia hlau los tsim cov twj tso kua mis, impellers, li qub, thiab lwm yam ntawm cov twj siv tshuaj (ua kom zoo dua nws cov tshuaj tiv thaiv thiab lub zog).
Automation / Robotics: Mechanical arm Cheebtsam, lub teeb yuag zog (kev ua kom zoo dua ntawm nws lub teeb yuag thiab siab rigidity).

Exercise thiab Leisure:Cov khoom xws li drone thav duab, tsheb kauj vab Cheebtsam, thiab kayak hniav muaj cov kev cai nruj heev rau qhov hnyav thiab rigidity.

 

Electronics thiab cov khoom siv:
Electronic enclosures: Cov rooj plaub lossis kev txhawb nqa sab hauv rau cov servers thiab cov khoom siv sib txuas lus.
Cov cuab yeej siab- kawg: Lub teeb yuag thiab siab - lub zog muaj zog rau cov kws tshaj lij- cov cuab yeej hluav taws xob qib.

LCF PP (Long Carbon Fiber Reinforced Polypropylene) yog cov khoom siv ua haujlwm siab -. Los ntawm kev siv tshuab fiber ntau ntev, nws ua tiav cov nqi qis thiab tshuaj lom neeg ntawm PP matrix nrog lub teeb hnyav, siab rigidity, siab zog thiab conductivity ntawm carbon fibers. Nws tsis yog tsuas yog hloov kho dua tshiab ntawm LGF PP yas pellet, tab sis kuj yog ib qho kev daws teeb meem zoo tshaj plaws rau ntau daim ntawv thov uas xav tau kev coj ua, kev tiv thaiv, lossis qhov hnyav hnyav, hloov tuag- nrum hlau. Kev nkag siab txog qhov tseem ceeb ntawm kev tswj xyuas qhov ntev ntawm fiber ntau thaum ua tiav yog tus yuam sij kom ua tiav nws lub peev xwm.
