LCF PEEK: Qhov "Limit" ntawm Kev Ua Haujlwm
Hauv "tsis tau tshawb nrhiav" ntawm cov cuab yeej niaj hnub no - txawm tias nws yog lub hiav txwv tob ntawm qhov tob ntawm kaum txhiab meters los yog lub tshuab nqus tsev ze ntawm -Lub ntiaj teb orbit - engineers tau sib sau ua ke ntsib teeb meem nyuaj: "qab nthab" ntawm cov khoom siv niaj hnub ua haujlwm. Txawm hais tias cov hlau (xws li titanium alloys thiab siab - steels) muaj zog, lawv qhov hnyav, kev tiv thaiv corrosion, thiab cov txheej txheem ua haujlwm nyuaj tau dhau los ua qhov hnyav rau kev tsim qauv; Thaum cov khoom siv hluav taws xob ib txwm muaj lub teeb yuag, lawv sai "muab" nyob rau hauv qhov kub thiab txias, kev kub siab, thiab kev tawm tsam ntawm cov tshuaj corrosive.
Qhov no yog qhov tseem ceeb ntawm LCF PEEK (ntev carbon fiber reinforced polyether ether ketone) puas ua rau nws zoo li. Cov tsoos luv luv fiber reinforced plastics yog qhov tseem ceeb tseem "yas matrices" nrog suav tsis txheeb cais "cov ntsiab lus txhawb zog" ntab hauv lawv. Txawm li cas los xij, qhov tseem ceeb ntawm kev tsim kho tshiab ntawm LCF PEEK compound resin nyob rau hauv qhov tseeb tias nws tsim ib "txuas ntxiv peb -siv carbon fiber ntau (3D Structural Skeleton)" nyob rau hauv cov khoom. Thaum lub sij hawm txhaj tshuaj molding txheej txheem, cov pa roj carbon fiber ntau ntev (feem ntau tshaj 5 hli nyob rau hauv ntev) interweave thiab sib tshooj nrog ib leeg, tsim ib tug ua tiav fiber ntau network nyob rau hauv cov khoom uas muaj peev xwm ntawm nws tus kheej dais kev nyuaj siab.
Qhov zoo ntawm CF PEEK yog dab tsi?
Structure thiab mechanical zog
Revolutionary cuam tshuam tsis kam thiab siab toughnessNtev carbon fibers (LCF) tsim ib qho peb -dimensional "bearing moj khaum" nyob rau hauv cov khoom. Thaum muaj kev cuam tshuam, cov qauv network no tuaj yeem cuam tshuam zoo thiab nqus lub zog. Nws qhov kev cuam tshuam lub zog thiab kev puas ntsoog toughness yog qhov zoo tshaj plaws ntawm cov khoom siv fiber ntau luv los yog iav fiber ntau.
Zoo heev qaug zog kuj thiab durabilityCov txheej txheem fiber ntau txuas ntxiv ua rau nws tsis tshua muaj peev xwm tsim microcracks lossis raug kev txom nyem los ntawm kev qaug zog tsis ua haujlwm nyob rau hauv lub sijhawm ntev -, siab - zaus cyclic loads, ua kom lub neej ntev heev rau cov khoom siv nyob rau hauv hnyav hnyav.
Thermodynamics thiab Dimensional Stability
Siab siab heev -kub rigidity thiab creep kujLCF PEEK cov ntaub ntawv tsis yog tsuas yog txais tau qhov kub thiab txias tsis kam ntawm PEEK matrix, tab sis qhov tseem ceeb tshaj, qhov "anchoring" nyhuv ntawm LCF lub moj khaum ua rau nws muaj zog heev (modulus) ntawm qhov kub thiab txias thiab tiv taus siab -kub creep nyob rau hauv ntev - lub sij hawm loading.
Tsawg thermal expansion coefficientPiv nrog rau cov hlau 'tsis tshua muaj thermal expansion coefficient (CLTE) Nws cov kab hluav taws xob thermal expansion coefficient yog qhov qis heev thiab tsis sib xws, nyob ze lossis qis dua li ntawm aluminium alloys. Qhov no txhais tau hais tias nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias hloov, cov khoom siv tsis tshua muaj thermal expansion lossis contraction, kom ntseeg tau tias qhov siab ruaj khov rau qhov haum haum (xws li bearings, gears).
Functionality thiab ib puag ncig kam rau ua
Sab saum toj -cov tshuaj tiv thaiv corrosion thiab hydrolysis tsis kam. Nws zoo kawg nkaus txais qhov "chemical inertness" ntawm PEEK matrix thiab tuaj yeem tiv taus qhov yaig ntawm yuav luag tag nrho cov tshuaj hnyav.
Tsim thiab tsim tau zoo
Nws tuaj yeem ua tiav kev txhaj tshuaj molding. Tsis zoo li cov thermosetting composites (uas yuav tsum tau compression curing) los yog hlau (uas yuav tsum tau CNC txiav), LCF PEEK khaws cov khoom siv thermoplastic, tso cai rau kom muaj txiaj ntsig thiab tus nqi - ua haujlwm zoo los ntawm kev txhaj tshuaj molding txheej txheem.
Kev tsim qauv yooj yim heev thiab kev sib xyaw ua ke. Nws tso cai rau kev sib koom ua ke ntawm ntau yam hlau ywj siab rau hauv ib qho kev txhaj tshuaj molded ib feem, txo cov nqi sib dhos thiab cov ntsiab lus tsis ua haujlwm.
LCF PEEK siv rau dab tsi?

FAQ
Q: Dab tsi yog qhov txawv ntawm LCF PEEK thiab SCF PEEK?
A: Qhov sib txawv tseem ceeb nyob hauv cov qauv sab hauv. Hauv SCF PEEK, nws tsuas yog ib qho "filler" dispersed hauv cov yas; thaum nyob rau hauv LCF PEEK, cov carbon fibers ntev nyob rau hauv cov khoom "interlock" nrog rau ib leeg, tsim ib tug peb -dimensional load- bearing moj khaum.
Q: Cov khoom no puas nyuaj rau kev ua haujlwm? Nws puas xav tau cov cuab yeej tshwj xeeb?
A: Nws xav tau lub tshuab txhaj tshuaj molding muaj peev xwm ncav cuag qhov kub thiab txias thiab hnav-cov ntsia hlau tiv taus, thiab muaj cov cai tshwj xeeb rau pwm tsim los tiv thaiv qhov ntev ntawm fiber ntau. Txawm li cas los xij, nws tseem poob rau hauv qeb ntawm kev txhaj tshuaj molding thiab tsis xav tau lub sijhawm ntev - kho cov khoom siv thermosetting.
Q: Tus nqi ntawm LCF PEEK yog siab heev. Vim li cas ho tsis siv hlau?
A: "tag nrho cov nqi" yuav tsum tau txiav txim siab, tsis yog "tus nqi khoom siv". Lub teeb yuag nws nqa tuaj yeem txo qis kev siv hluav taws xob hauv thaj chaw xws li aviation thiab tsheb, thiab nws cov kev tiv thaiv corrosion kuj txo cov nqi txij nkawm thoob plaws hauv lub neej.
