Tsis txhob cia siab rau Carbon Fiber; Tus Vaj Ntxwv ntawm Tus Nqi no -kev ua tau zoo yog Qhov Kev Muag Khoom tiag tiag.

I. Dab tsi yog fiberglass?

 

Cov khoom siv raw raufiberglassyeej muaj ntau heev: quartz xuab zeb, limestone, boric acid, thiab lwm yam Yog, tib yam raw khoom siv nyob rau hauv lub qhov rais iav nyob rau hauv peb lub neej txhua hnub.

 

Los ntawm melting ntawm qhov kub thiab txias (kwv yees li 1200{2}}1400 degree) thiab kos rau hauv fibers siv platinum spinneret, fiberglass nrog ib txoj kab uas hla ntawm 5-20 micrometers yuav tau-ntau npaum li cas finer tshaj tib neeg cov plaub hau (kwv yees li 80 micrometers).

 

Txawm hais tias lawv cov thinness, lub zog tensile ntawm ib qho filament tuaj yeem ncav cuag 2000-3500 MPa, zoo ib yam li cov hlau hlau.

 

Cov ntaub ntawv qhov chaw: Cov lus piav qhia ntawm cov txheej txheem fiberglass ntau lawm yog kev paub txog kev lag luam; Cov cuab yeej cuab tam cov ntaub ntawv hais txog lub teb chaws tus qauv GB / T 18369-2022 "Glass Fiber Untwisted Roving".

 

II. Cov ntaub ntawv hais txog: Vim li cas iav Fiber yog "Tus Vaj Ntxwv ntawm Tus Nqi-Kev Ua Tau Zoo"?

 

Cov pa roj carbon fiber ntau yog 2-3 npaug zog dua fiberglass, tab sis nws tus nqi yog 10-20 npaug siab dua. Hauv ntau qhov xwm txheej uas "qhov kawg ua tau zoo" tsis tas yuav tsum tau, fiberglass nqi-zoo yog qhov zoo dua.

 

Siv ib qho piv txwv: carbon fiber zoo li lub tsheb kis las - sab saum toj -tier kev ua tau zoo, sab saum toj -tier nqe; fiberglass zoo li lub tsheb thauj khoom - zoo txaus, ruaj khov, thiab pheej yig. Kev lag luam kev lag luam tsis xav tau txhua lub tsheb los ua lub tsheb kis las; cov tsheb thauj khoom yog cov neeg ua haujlwm tiag tiag.

 

Cov ntaub ntawv Sources:

 

Kev sib piv ntawm Carbon Fiber / Glass Fiber Composite Performance Data: Raws li "Composites Market Report 2025" thoob ntiaj teb cov ntaub ntawv sib xyaw ua lag luam tshaj tawm los ntawm Composites United, thiab carbon fiber mechanical properties database luam tawm hauv Nature's Scientific Data journal.

 

Carbon Fiber Reinforced Composite Material Market Cov ntaub ntawv: Raws li QYResearch cov ntaub ntawv tshawb fawb "Lub Ntiaj Teb Carbon Fiber Reinforced Composite Material Industry Overall Scale, Major Enterprises 'Domestic and International Market Share and Ranking in 2026," lub ntiaj teb carbon fiber reinforced composite material market sales mus txog 50.9 billion yuan hauv 2025.

 

Material Performance Standards: Hais txog lub teb chaws tus qauv GB/T 26752-2020 "Polyacrylonitrile-based Carbon Fiber" thiab GB/T 18369-2022 "Glass Fiber Untwisted Roving."

 

III. Tsib qhov zoo ntawm iav Fiber

 

1. Lub teeb yuag thiab lub zog siab: GFRP tsuas muaj 1/4 qhov ntom ntawm cov hlau, tab sis sib piv lub zog. GFRP I-beam hnyav tsuas yog li 1/3 ntawm cov nqaj hlau nrog tib lub load-cov kabmob muaj peev xwm. Cov ntaub ntawv Source: Cov ntaub ntawv sib piv ntawm cov khoom siv kho tshuab tau hais txog kev sib piv ntawm kev siv cov pa roj carbon fiber ntau thiab iav fiber ntau luam tawm hauv phau ntawv journal *Composites Part A*, ScienceDirect. Txoj kev tshawb no tau pom tias qhov ntom ntom ntawm fiber ntau -cov khoom siv ntxiv yog 1.7-2.0 g / cm³.

 

2. Corrosion Resistance yog qhov tseem ceeb
Qhov no yog GFRP lub forte. Hlau xeb, txhuas corrodes, tab sis GFRP tuaj yeem tiv taus ntau xyoo ntawm kev raus dej hauv dej hiav txwv, kua qaub, thiab alkalis, tseem tshuav.

Tiag -cov piv txwv hauv ntiaj teb: Hydrochloric acid cia tanks hauv cov nroj tsuag tshuaj, cable tais los ntawm hiav txwv, thiab cov kav dej hauv cov chaw kho dej phwj- cov khoom siv hlau hauv cov chaw no tsis pub dhau ob peb xyoos, tab sis GFRP tuaj yeem kav ntev dua 20 xyoo.

 

3. Inherent rwb thaiv tsev
Cov pa roj carbon fiber ntau yog cov khoom siv hluav taws xob (uas yog qhov tsis zoo hauv qee qhov xwm txheej), tab sis iav fiber ntau yog qhov zoo tshaj plaws insulator.

 

Qhov no yog vim li cas: Circuit Court boards siv iav fiber ntau daim ntaub ua substrate; insulated ladders nyob rau hauv substations yuav tsum tau ua los ntawm fiberglass; radar radomes yuav tsum tau ua los ntawm cov iav fiber ntau sib xyaws -vim nws tsis thaiv electromagnetic tsis.

 

Cov ntaub ntawv Source: Cov ntawv thov saum toj no tau piav qhia raws li kev paub txog kev lag luam. Hais txog kev siv fiberglass hauv cov khoom siv hluav taws xob, xa mus rau lub teb chaws tus qauv GB / T 18373-2013 "E-fiberglass daim ntaub rau cov ntawv luam tawm Circuit Court".

 

4. Tus nqi qis

 

GFRP cov ntaub ntawv raw -quartz xuab zeb thiab limestone- muaj ntau nyob hauv ntiaj teb. Cov txheej txheem tsim khoom kuj tseem paub tab, thiab tus nqi qis dua li carbon fiber ntau.

 

Los tsim ib qhov profile 1-meter ntev:

Fiberglass: kaum yuan

Carbon fiber ntau: pua pua mus rau txhiab yuan

 

5. Zoo Wave Transmission

 

Qhov no yog fiberglass qhov tshwj xeeb kom zoo dua. Radar signals tuaj yeem nkag mus rau fiberglass yam tsis muaj kev cuam tshuam, tab sis yuav cuam tshuam los ntawm cov hlau.

Yog li ntawd, koj yuav pom:

Lub dav hlau radomes yog ua los ntawm cov fiberglass dawb

Lub "tsis paub lub tog raj kheej" tom qab lub xov tooj ntawm tes yees kuj yog fiberglass

Cov npog ntawm tub rog stealth antennas

Txhua yam yog ua los ntawm GFRP.

 

IV. Fiberglass siv qhov twg? Los ntawm Ntuj mus rau hauv av

 

Kev tsim kho thiab Infrastructure

 

Qhov no yog GFRP lub khw loj tshaj plaws.

• Txuas hniav: Txhua yam -GFRP txuas hniav, GFRP choj lawj paving, GFRP guardrails

• Cov ntaub ntawv tshwj xeeb ntawm cov cua turbine blades: Tam sim no, cov cua turbine cov hniav feem ntau tshaj 80 meters, thiab cov cua turbine tuaj yeem ncav cuag 100 meters. Raws li NASA cov ntaub ntawv tshaj tawm kev tshaj tawm los ntawm Nyiv Aerospace Exploration Agency (JAXA), qhov sib txawv ntawm elastic modulus ntawm unidirectional nruam fiber system thiab luv fiber system ntawm IM7 carbon fiber / PEKK cov khoom siv nyob rau hauv peb lub ntsiab lus qhia yog tsawg dua 15%, thiab lub zog tensile thiab compressive yog qhov sib npaug. Lub tshuab no muab cov ntaub ntawv txhawb nqa rau kev tsim kho kom zoo ntawm cov khoom siv loj loj xws li cua turbine hniav. V. Lub neej yav tom ntej ntawm Fiberglass: Ntsuab, siab -Kev ua tau zoo, thiab ntse

 

Txoj Kev 1: Boron-dawb thiab fluorine-Dawb ib puag ncig tus phooj ywg Fiberglass

Kev tsim fiberglass ib txwm tso tawm me me ntawm boron thiab fluorine. Cov qauv tam sim no yog theem tawm boron - thiab fluorine - muaj cov formulations thiab tsim tiag tiag "ntsuab fiberglass."

 

Txoj Kev 2: Siab -Kev Ua Haujlwm Thermoplastic Composites

Ib txwm GFRP feem ntau siv cov thermosetting resins, uas tsis tuaj yeem rov ua dua. Tam sim no, siv cov thermoplastic resins (xws li PP thiab PA) raws li cov matrix tau dhau los ua qhov kub.

 

Core Advantage: Recyclable - Cov ntaub ntawv pov tseg tuaj yeem raug crushed thiab rov- txhaj rau hauv pwm.

 

Raws li kev tshawb fawb luam tawm nyob rau hauv phau ntawv journal *Composites Part A*, recycled carbon fiber reinforced PA66 composites can achieve more than 80% of the physical properties of virgin carbon fiber composites and can be used for lightweighting non-structural components.

 

Txoj Kev 3: Kev Txawj Ntse thiab Kev Saib Xyuas Online

Embedding fiber ntau optic sensors hauv GFRP cov qauv tseem ceeb xws li cov hniav thiab cov txuas hniav tso cai rau -lub sij hawm saib xyuas kev lim dej thiab qhov kub thiab txias. Cov qauv kev noj qab haus huv tau saib xyuas kom meej los ntawm lub backend.

 

Related National Projects: Raws li cov ntaub ntawv tshaj tawm los ntawm National Basic Science Public Science Data Center, National Key Research and Development Program project "Large Tonnage Carbon Fiber Composite Cables for Bridges of the Sichuan-Tibet Railway" (Project No.: 2021YFB3704400) tau ua kev tshawb fawb txog kev khoov thiab kev cuam tshuam ntawm cov khoom siv ua haujlwm siab, kev ua haujlwm siab thiab kev ua haujlwm siab. txoj haujlwm). Cov ntaub ntawv muaj ntau dua 6,000 cov ntaub ntawv xeem thiab cov ntaub ntawv ntim txog 7.16 GB.
