Cov pa roj carbon fiber ntau cov khoom siv sib xyaw ua ke tau siv dav hauv ntau qhov kev lag luam xws li thev naus laus zis thev naus laus zis, tsev scooters, thiab cov khoom siv hluav taws xob siab vim lawv lub teeb yuag, ua haujlwm siab, thiab muaj zog corrosion kuj. Vim tias nws cov khoom lag luam zoo tshaj plaws nyob rau hauv qhov chaw ntub dej thiab qhov kub thiab txias, qhov kub thiab txias, thiab kev sib cog lus nruab nrab, cov kab lus no yuav ntev mus kawm txog cov kev hloov hauv kev ua haujlwm thiab cov txheej txheem ntawm carbon fiber reinforced composite cov ntaub ntawv nyob rau hauv hnyav ib puag ncig nrog uncontrollable humid temperatures, thiab ua ke. lawv nrog cov ntsiab lus kev sim tshwj xeeb thiab cov ntaub ntawv thov raug txheeb xyuas.
Ib puag ncig uas tsis tuaj yeem tswj tau cov av noo thiab qhov kub thiab txias muaj kev cuam tshuam ntau dua rau kev ua haujlwm thiab cov txheej txheem ntawm cov khoom siv carbon fiber ntau. Los ntawm ib qho kev xav ntawm kev xav, ib puag ncig kev laus sov yuav ua rau muaj kev puas tsuaj rau qhov cuam tshuam ntawm cov resin thiab fiber. Microscopically, cov resin thiab fiber yuav sib cais. Qhov kev sib txuas no Kev sib cais yuav ua rau txo qis ntawm tag nrho cov kev ua tau zoo ntawm cov khoom sib xyaw, yog li cuam tshuam rau cov khoom siv kho tshuab. Los ntawm kev pom macro, cov khoom siv kho tshuab ntawm cov khoom sib xyaw yuav raug txo kom tsawg, ua rau muaj kev hem thawj rau kev nyab xeeb ntawm tag nrho cov qauv.
Humid thermal ib puag ncig tuaj yeem ua rau kev ua haujlwm tsis zoo:
Lub zog tensile: Lub zog tensile ntawm cov khoom sib xyaw txo qis, tshwj xeeb tshaj yog nyob rau hauv cov huab cua siab thiab kub; Interlaminar shear zog: Kev puas tsuaj ntawm kev sib tshuam ntawm cov resin thiab fiber ntau ua rau txo qis hauv interlaminar shear zog ntawm cov ntaub ntawv sib xyaw; Modulus: Tensile modulus Volume poob me ntsis.
Nyob rau hauv cov ntaub ntawv "Comparative Study on Moisture and Heat Aging Properties of Different Hom Fiber Reinforced Composite Materials", unidirectional carbon fiber composites (CFRP), iav fiber ntau composites (GFRP), thiab flax fiber composites (FRP) nrog ib tug carbon fiber cov ntsiab lus ntawm 60% 6 tau ua. Kev ntsuas sov-kub kub tau ua tiav, thiab qhov kev sim tau pom tias tom qab kev laus hauv qhov chaw kub thiab av noo, lub zog tensile thiab interlaminar shear lub zog ntawm iav fiber ntau cov ntaub ntawv txo qis, thiab tensile modulus poob me ntsis. Tom qab ziab, cov khoom tensile zoo zoo, tab sis lub zog interlaminar shear yog qhov nyuaj rau kho. Nws tuaj yeem pom tias qhov kev ua haujlwm tsis zoo xws li iav fiber ntau hydrolysis thiab kev sib cuam tshuam cuam tshuam uas tshwm sim thaum lub sij hawm kev laus ntawm iav fiber ntau cov ntaub ntawv yog qhov hloov tsis tau.
Flax fiber composites yuav plasticize tom qab nqus dej, thiab lub zog tensile yuav nce me ntsis, thaum lub tensile modulus thiab interlaminar shear zog yuav nyob twj ywm tom qab ib tug ntse txo. Tom qab ziab, lub zog tensile tsis tuaj yeem rov qab los yog txo qis, thaum lub tensile modulus thiab interlaminar shear zog nce ntau. Qhov no tshwm sim yog ze ze rau cov kev hloov xws li ya raws plasticization, expansion, thiab degradation ntawm fibers thiab matrix.
Cov pa roj carbon fiber ntau sib txawv ntawm ob cov ntaub ntawv hais saum toj no. Raws li lub sijhawm laus zuj zus, lub zog tensile ntawm carbon fiber composites yuav luag tsis hloov, tab sis lub zog interlaminar shear zog txo me ntsis. Tom qab ziab, cov khoom tensile thiab interlayer shear zog rov qab mus rau lawv qhov qub qub. Nws tuaj yeem pom tau tias txawm tias cov khoom siv carbon fiber ntau cuam tshuam rau lub sijhawm laus hauv qhov chaw ntub thiab kub, nws yuav rov qab los rau nws cov duab qub tom qab ziab thiab muaj cov av noo thiab kub tsis kam.
Txawm hais tias carbon fiber ntau cov ntaub ntawv muaj kev tiv thaiv zoo dua rau cov dej noo thiab cua sov, cov khoom siv kho tshwj xeeb tseem xav tau hauv cov ntawv thov kev tsim khoom tiag tiag kom ntseeg tau tias cov khoom siv tau zoo dua. Nyob rau hauv tsab ntawv tshaj tawm "Kev Tshawb Fawb Txog Kev Ua Haujlwm Ntawm Qhov Chaw Ua Haujlwm sov ntawm Kev Ua Haujlwm Hauv Tsev CCF30 Carbon Fiber thiab CC [300/EH503R3 Composite Materials", kev tshawb fawb tau tshawb fawb txog kev laus ntawm cov khoom siv carbon fiber ntau hauv cov khoom kub thiab av noo. Txoj kev tshawb fawb tau ua pov thawj tias: CCF300/EH503R3 cov ntaub ntawv sib xyaw tau sim hauv 1,000- xeev cov xwm txheej ntawm chav tsev kub. Nyob rau hauv ib puag ncig, 90% ntawm tensile fracture morphology qhia matrix puas, thiab cov carbon fiber tsis pom tseeb puas. Qhov saum npoo ntawm lub mesh fiber yog qhwv nrog ntau cov resin, uas qhia tau hais tias cov carbon fiber thiab resin muaj zog interfacial bonding zog. Nyob rau hauv 93 degree / qhuav qhov chaw kuaj, ib qho me me ntawm resin tearing thiab me ntsis carbon fiber debonding tshwm sim. Tom qab kev kho mob nyob rau hauv ib qho chaw sov sov, vim qhov kub ntawm qhov ntsuas qhov chaw, ib tug me me ntawm cov kab nrib pleb tshwm nyob rau hauv lub fiber axis, thiab tus nqi ntawm resin qhwv nyob rau hauv lub fiber nto txo. Debonding nce thiab lub zog sib txuas ntawm fiber ntau thiab resin tsis muaj zog. Txawm li cas los xij, ntawm 132 degree / ntub ntsuas kub, carbon fiber thiab resin tseem tuaj yeem ua ke nruj, uas qhia tau hais tias CCF300 / EH503R3 cov khoom sib xyaw muaj kev sib cuam tshuam zoo heev thiab ya raws thiab cua sov.
Hauv cov ntsiab lus, raws li cov khoom siv tiag tiag thiab kev tsim khoom dhau los, peb tuaj yeem tsim cov qauv tsim cov khoom lag luam rau cov khoom siv sib xyaw carbon fiber ntau raws li lub hom phiaj, ntsuas kev ua tau zoo raws li cov khoom siv, thiab pib ntxiv los ntawm resin matrix, carbon fiber precursor qauv. , kev hloov kho cov txheej txheem, txheej txheem molding, thiab lwm yam, txhawm rau txheeb xyuas qhov tsim nyog tsim qauv los xyuas kom meej tias nws qhov kev thov tiag tiag. Qhov no yog raws nraim lub hauv paus ntsiab lus ntawm Tuam Tshoj los saib cov khoom kos duab ua ntej thiab tom qab ntawd nkag siab txog nws cov khoom siv yuav tsum tau ua, thiab tom qab ntawd muab cov qauv tsim tom qab.
Nrog rau kev nce qib hauv cov khoom siv tas mus li, qhov ntub thiab kub ua haujlwm ntawm cov ntaub ntawv carbon fiber ntau tuaj yeem txhim kho ntxiv los ntawm kev hloov kho interface thiab txhim kho kev ua haujlwm ua ntej, thiab carbon fiber ntau derivatives tseem yuav ua lub luag haujlwm tseem ceeb thiab tseem ceeb hauv ntau lub teb. .
