Koj puas paub tias qhov kev ua tiav ntawm kev sib koom ua ke ntawm fiberglass thiab basalt fiber ntau tau muab cov kev daws teeb meem rau lub teeb yuag lub zog tshiab?
Kev sib koom ua ke ntawm kev sivfiberglassthiab basalt fiber ntau tawg los ntawm lub fwj ntawm ib cov ntaub ntawv, muab cov kev daws teeb meem rau lub teeb yuag tshiab lub zog tsheb los ntawm cov khoom siv sib xyaw ua ke (25% nce hauv flexural zog), txheej txheem kev tsim kho tshiab (lub voj voog molding shortened mus rau 100 vib nas this), thiab tag nrho lub neej - voj voog optimization (nqi txo 20%-25%).
Tsav los ntawm ob qho tib si automotive lightweighting thiab sustainable kev loj hlob, lub synergistic daim ntawv thov ntawmfiberglassthiab basalt fiber yog reshaping thev naus laus zis paradigm ntawm lub tsheb lub cev yam ntxwv Cheebtsam. Los ntawm cov khoom siv ntxiv, cov txheej txheem kev sib xyaw ua ke, thiab tag nrho lub neej- kev ua kom zoo dua qub, qhov "nruj-" yoog raws" fiber ntau ua ke tsis yog tsuas yog kov yeej cov kev ua haujlwm tsis zoo ntawm cov ntaub ntawv nkaus xwb tab sis kuj teeb tsa cov qauv ntsuas tshiab hauv kev tswj hwm tus nqi, kev hloov pauv ib puag ncig, thiab kev tiv thaiv kev nyab xeeb, dhau los ua qhov tseem ceeb hauv kev siv thev naus laus zis ntawm lub zog tshiab.
Synergistic Breakthroughs hauv Cov Khoom Siv Ua Haujlwm
Los ntawm Ib Leeg Reinforcement rau System Optimization
1. Ua kom muaj zog ntawm cov cuab yeej cuab tam
Fiberglassboasts qhov zoo ntawm lub zog siab (lub zog tensile 300-}500 MPa) thiab siab modulus (70-80 GPa), thaum basalt fiber ntxiv rau nws nrog kev cuam tshuam ntau dua (elongation ntawm tawg 3.2% vs. fiberglass 2.5%) thiab kub-kub tsis kam (siab kub tiv taus 800 degree.fiberglass500 degree). Los ntawm hybrid fiber ntau tsim (piv txwv li, 30% basalt fiber ntau + 70% fiberglass), cov khoom sib xyaw lub zog flexural tuaj yeem ncav cuag 1200 MPa, 25% kev txhim kho ntawm cov ntshiab fiberglass, thaum tib lub sij hawm nce kev cuam tshuam los ntawm 30%, ua tau raws li CNCAP tsib- lub hnub qub kev sib tsoo cov qauv. Piv txwv li, basalt / fiberglass hybrid qhov rooj sab hauv vaj huam sib luag tsim los ntawm Qianjia Group txo qhov hnyav los ntawm 35% thaum tuav cov txheej txheem lub zog, thiab txuas ntxiv ntsev tsuag corrosion kuj mus rau ntau tshaj 15 xyoo.
2. Synergistic Enhancement ntawm Environmental Adaptability
Lub ntuj huab cua tsis kam ntawm basalt fiber (60% qis dua UV kev laus dua lifiberglass) combined with the chemical corrosion resistance of fiberglass allows the composite material to maintain over 90% of its mechanical properties within a wide temperature range of 40℃ to 80℃. Jilin Tongxin Basalt Technology's battery casing products, through a composite structure of basalt fiber outer protection and fiberglass inner reinforcement, successfully resist the high temperatures (>150 degree) thiab electrolyte corrosion ntawm lub zog tshiab lub tsheb roj teeb pob, ua tiav daim ntawv pov thawj UL94V0 nplaim hluav taws, nrog rau qhov hluav taws kub tiv thaiv ob theem siab dua cov tsoos hlau casings.
Txheej txheem Innovation thiab nqi optimization
Los ntawm Laboratory mus rau Mass Production
1. Precise Control ntawm Prepreg Technology
Siv cov txheej txheem thermosetting resin impregnation, cov ntsiab lus fiber ntau (60-70%) thiab resin faib uniformity tuaj yeem tswj tau. Patented thev naus laus zis qhia tau hais tias lub zog tensile ntawm basalt / fiberglass hybrid prepreg tuaj yeem ncav cuag 85% ntawm carbon fiber prepreg, thaum tus nqi tsuas yog 1/4. Kunshan Rouwei Environmental Technology's yob - mus rau - yob cov kab ntau lawm ua tiav cov khoom sib xyaw fiber ntau los ntawm kev sib koom ua ke ntau spinneret, txo nqi tsev rau 2.95 yuan / square meter, nce qib ntawm cov tsoos PP meltblown ntaub.
2. Ib qho kev hloov pauv ntawm kev ua haujlwm zoo hauv compression molding
Kev sib xyaw ua ke ntawm autoclave molding tshuab (kub 150 degree, siab 0.3MPa) thiab ceev-kho resin txo lub voj voog molding ntawm cov khoom siv los ntawm 2 teev siv cov txheej txheem hlau ib txwm siv rau 100 vib nas this. Tom qab siv cov thev naus laus zis no, lub tsheb tsim cov khoom lag luam subframe txo cov naj npawb ntawm qhov chaw los ntawm 17 mus rau 1, nce kev ua tau zoo los ntawm 8 zaug, thaum tib lub sijhawm nce cov ntim fiber ntau mus rau 35% thiab ob npaug ntawm kev ua haujlwm compression piv rau cov txheej txheem ib txwm muaj.
3. Kev txo nqi tseem ceeb hauv lub neej voj voog
Txawm hais tias tus nqi pib ntawm basalt fiber ntau yog 15% siab dua li ntawm fiberglass, kev txhim kho kev siv hluav taws xob (58% nce hauv ntau) thiab txo tus nqi kho (70% txo qis hauv kev hloov pauv ntau zaus) uas ua rau cov khoom hnyav tuaj yeem txo cov nqi ntawm lub neej los ntawm 2025%. Siv lub tshuab hluav taws xob ntshiab SUV ua piv txwv, tom qab siv lub roj teeb hybrid fiber ntau, lub tsheb txuag kwv yees li 800 yuan hauv cov nqi hluav taws xob ib xyoos ib zaug, thiab cov peev nyiaj them rov qab yog luv rau 3.5 xyoo.
Kev Tshawb Fawb Kev Lag Luam thiab Daim Ntawv Thov Kev nthuav dav
Los ntawm Cov Txheej Txheem Txheej Txheem mus rau Kev Txawj Ntse Kev Koom Tes
1. Kev Tshawb Fawb Txog Kev Ua Haujlwm ntawm Cov Khoom Siv Ntsuas
Roj teeb Casing: Jilin Tongxin's basalt / fiberglass composite roj teeb casing yog 40% sib zog dua aluminium alloy, nrog lub zog compressive ntawm 500kN (txheej txheem ntau dua lossis sib npaug rau 130kN). Nws dhau qhov kev ntsuam xyuas rab koob tsis tau qhib nplaim taws thiab tau siv ntau yam qauv CATL.
Lub Cev Ncej: Lub fuselage ntawm ib tuj-chav kawm UAV los ntawm United Aircraft Group siv cov khoom siv sib xyaw no, ua kom muaj kev ruaj ntseg txawm nyob ntawm qhov siab ntawm 6500 meters, thiab txhim kho cua tiv thaiv los ntawm qib 6 txog qib 8.
Chassis Cheebtsam: Lub tuam txhab tsheb lag luam lub basalt / fiberglass hybrid nplooj springs muaj lub neej ntev ob zaug ntawm cov khoom hlau, thaum txo qhov hnyav los ntawm 45%, txuag kwv yees li 1.2 tons ntawm roj ib lub tsheb txhua xyoo.
2. Kev nthuav dav kev lag luam uas tau tsav los ntawm Txoj Cai Ib puag ncig
EU txoj cai lij choj roj teeb tshiab xav kom cov khoom siv roj teeb kom muaj tus nqi rov ua dua los yog sib npaug li 85% los ntawm 2030, thiab basalt fiber ntau cov khoom siv rov ua dua tshiab (cov khoom siv rov ua dua tshiab dua 92%) ua rau nws yog qhov kev xaiv zoo tshaj. Tuam Tshoj "Kev Npaj Ua Haujlwm rau Siab-Kev Txhim Kho Zoo ntawm Kev Lag Luam Cov Khoom Siv Tshiab" muab 15% peev nyiaj pab rau cov khoom siv sib xyaw fiber ntau, ncaj qha txhawb kev lag luam xav tau. Kev lag luam thoob ntiaj teb loj rau tsheb basalt fiber ntau yog kwv yees kom ncav cuag $ 190 lab los ntawm 2030, nrog CAGR ntawm 9.6%.
3. Yav tom ntej Technological Evolution Directions
Kev sib xyaw ua haujlwm: "Smart structural Cheebtsam" embedded nrog fiber ntau optic sensors tuaj yeem saib xyuas kev ntxhov siab hauv lub sijhawm (qhov tseeb ± 5MPa), thiab ua ke nrog AI algorithms los txhim kho lub voj voog tu, tag nrho lub neej - tus nqi voj voog tuaj yeem raug txo los ntawm 35%.
Bio-raws li lwm txoj kev: PLA/basalt fiber ntau hybrid khoom tsim los ntawm Fudan University txo cov pa roj carbon monoxide los ntawm 79% piv rau roj av- cov ntaub ntawv raws thiab tau dhau EU EN 13432 biodegradability ntawv pov thawj. Nws cov nqi yuav tsum tau sib npaug nrog cov khoom siv ib txwm siv los ntawm 2027.
Ib puag ncig Adaptability: Boron- muaj cov khoom siv basalt fiber ntau muaj peev xwm adsorption rau cov xov tooj cua iodine-131 17 npaug ntawm cov khoom siv ib txwm siv, ua rau lawv tsim nyog rau kev tiv thaiv hluav taws xob hauv tsheb thaum muaj xwm ceev nuclear.
Daim ntawv thov kev sib koom ua ke ntawm fiberglass thiab basalt fiber tsis yog ib qho yooj yim superposition ntawm cov khoom siv, tab sis ib qho tseem ceeb qhia ntawm kev tsim tsheb tsim kev lag luam hloov pauv ntawm "ib zaug- cov khoom sib tw" rau "kev daws teeb meem." Nrog rau kev loj hlob ntawm cov txheej txheem prepreg, kev poob qis hauv cov nqi tsim khoom loj, thiab kev txhawb nqa txoj cai, kev nkag mus ntawm hybrid fibers hauv lub tsheb lub cev cov txheej txheem yuav tsum siab tshaj 40% los ntawm 2030, propelling lightweighting of new energy vehicles into a new era of "kev ua tau zoo, nqi, thiab kev tiv thaiv ib puag ncig". Raws li cov kws tshaj lij los ntawm Suav Society for Composite Materials tau hais tias, "Qhov kev hla no - ciam teb kev sib koom ua ke los ntawm pob zeb hluav taws xob thiab kev lag luam kev vam meej yog rov txhais lub neej yav tom ntej ntawm cov khoom siv tsheb."
