Daim ntawv thov teb ntawm Aramid Fiber
Nws yog dav siv nyob rau hauv ntau lub teb xws li aerospace, tsheb, electromechanical, kev tsim kho, thiab kev ua si nyob rau hauv kuv lub teb chaws, thiab yog ib tug ntawm cov indispensable ntaub ntawv nyob rau hauv lub neej yav tom ntej.
Aviation sector
Aramid fiber ntau muaj qhov ntom ntom, siab zog thiab zoo corrosion kuj. Nws tuaj yeem siv los tsim cov khoom siv dav dav yoj-pob tshab xws li cov foob pob hluav taws foob pob hluav taws lub cav, lub dav hlau, lub dav hlau fuselages, lub ntsiab tis, thiab tus Tsov tus tw fins, nrog rau cov khoom siv uas tuaj yeem tiv taus cov quab yuam. Cov txheej txheem ntau txheej honeycomb board npaj los ntawm impregnating aramid daim ntaub nrog epoxy resin los tsim aramid prepreg thiab ncaj qha sib txuas nws mus rau honeycomb los yog ua npuas ncauj qauv muaj kev cuam tshuam zoo heev thiab electromagnetic yoj permeability. Lub super-hybrid composite laminate ua los ntawm aramid, nyias aluminium daim hlau, thiab epoxy weft-free fabrics uas yog overlapped thiab kub nias. Nws muaj qhov tshwj xeeb modulus thiab lub zog tshwj xeeb, thiab nws lub neej qaug zog yog 100 rau 1, 000 npaug ntawm cov phaj aluminium alloy. . Nws tuaj yeem siv rau ntawm lub dav hlau fuselages thiab lwm yam khoom siv. Resin-based reinforced composite cov ntaub ntawv npaj los ntawm aramid fibers yog siv nyob rau hauv dav hlau fuselages, uas yuav ua tau zoo heev txo qhov hnyav tag nrho ntawm lub dav hlau.
Tub rog teb
Nrog rau kev tsim cov tub rog tshiab riam phom xws li tshuaj riam phom thiab riam phom nuclear, ntau cov kev cai tshiab tau muab tso rau pem hauv ntej rau kev ua haujlwm ntawm cov tub rog tiv thaiv khaub ncaws: durability, lightness, mos mos, nplaim retardant, zoo ib puag ncig adaptability thiab camouflage, etc. Bulletproof vests thiab Cov kaus mom hlau Aramid fibers tuaj yeem hloov cov tsho nylon qub thiab cov kaus mom hlau-style. Ntxiv qhov tsim nyog ntawm aramid rau lub cev armor thiab kaus mom hlau tuaj yeem tsis tsuas yog ua rau lawv me me thiab lub teeb hauv qhov hnyav, tab sis kuj ua rau kom cov mos txwv tsis zoo los ntawm 40%. . Mos lub cev armor ua los ntawm qib high-qib bulletproof aramid weft-dawb ntaub thiab high-kev ua tau zoo polyethylene zaj duab xis muaj zoo bulletproof kev ua tau zoo thiab kub tsis kam tshaj ultra-siab molecular hnyav polyethylene fiber. Aramid fiber kuj tuaj yeem ua ke nrog lwm cov ntaub ntawv (xws li hlau, ceramics, thiab lwm yam) kom ua tau ntau yam muaj zog, cuam tshuam-resistant explosion-proof cov kaus poom, bulletproof shields, thiab mos txwv armor daim hlau. Tsis tas li ntawd, aramid fiber ntau yog muab tso rau ntawm phab ntsa sab hauv ntawm cov qauv kom nqus tau cov pa tawg thiab tiv thaiv shrapnel los ntawm kev ua phem rau tib neeg lub cev.
kev tsim kho kev lag luam
Aramid fiber ntau muaj ductility zoo dua li carbon fiber. Cov khoom nws tus kheej yog lub teeb yuag, dawb thiab yoog raws. Nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim kho cov phiaj xwm, tshwj xeeb tshaj yog thaum txhawb cov ntsiab lus tsis tu ncua. Vim nws softness, nws yog ib qho yooj yim mus use thaum reinforcing npoo thiab fab. Tsis xav tau chamfering. Woven aramid fibers rau hauv steel tuav tuaj yeem siv los ua cov cement-reinforced thav duab rau cov tsev loj. Ntxiv nrog rau qhov zoo ntawm lub zog siab thiab lub teeb yuag, nws kuj muaj qhov zoo ntawm corrosion kuj thiab zoo shear kuj.
Kev thauj mus los
Vim tias aramid fiber ntau muaj qhov ntom ntom ntom ntom, tuaj yeem tiv taus qhov kub thiab txias, thiab muaj qhov zoo adhesion rau roj hmab, nws tuaj yeem siv los ua lub log tsheb rau tsheb lossis dav hlau. Cov log tsheb ua los ntawm aramid fiber ntau muaj cov yam ntxwv ntawm lub teeb yuag, nyias lub log, tsis tshua muaj rolling tsis kam, siab log load-bearing muaj peev xwm, zoo hnav tsis kam, txiav tsis kam thiab puncture kuj, me me hauv av siab qhov chaw ntawm lub ntiajteb txawj nqus txav thaum siv log tsheb, thiab zoo heev steering. kev ua tau zoo. Nws yog qhov zoo, yooj yim rau dissipate tshav kub thiab tsis yooj yim rau deform, uas txhim kho lub caij kev nplij siab ntawm lub tsheb, ncua kev pab cuam lub neej ntawm lub log tsheb, thiab muaj peev xwm ua tau raws li cov kev cai siv log tsheb ntawm niaj hnub supersonic aircraft.
Kev lag luam hluav taws xob thiab hluav taws xob
Aramid fiber ntau muaj zog thiab modulus, tsis tshua muaj dielectric coefficient, thiab zoo electromagnetic yoj transmittance. Nyob rau hauv tib yam kev mob nruj, lub thickness ntawm radar kav hlau txais xov shielding daim hlau ua los ntawm aramid composite cov ntaub ntawv yuav raug txo los ntawm 30% piv nrog iav fiber ntau cov ntaub ntawv. %, qhov hluav taws xob nthwv dej xa hluav taws xob tau nce 10%; laminated substrate ua los ntawm aramid thiab epoxy, phenolic, polyimide thiab lwm yam resins muaj ib tug high linear expansion coefficient txuam nrog ceramics, thiab tsis nthuav nyob rau hauv qhov kev txiav txim ntawm thermal expansion thiab contraction. o tuaj. Nws yuav ua rau cov kab nrib pleb thiab tuaj yeem siv los ua cov ntawv tshwj xeeb hauv Circuit Court boards nyob rau hauv qhov chaw mounting thev naus laus zis, uas muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob me me thiab lub teeb yuag.
Siv cov yam ntxwv ntawm lub zog siab thiab kub tsis kam ntawm aramid fiber ntau, nws ua haujlwm ua "tus tswv cuab nruj" hauv cov khoom siv kho qhov muag los tiv thaiv qhov me me thiab tsis yooj yim kho qhov muag fiber ntau los ntawm kev elongated thiab deformed thaum raug nro, thiab yuav tsis cuam tshuam rau kev pabcuam. lub neej ntawm optical fiber. Kev sib kis ntawm lub teeb. Cov khoom sib xyaw ntawm aramid fiber ntau thiab carbon fiber muaj cov khoom ua haujlwm zoo thiab cov khoom siv semiconductor, thiab tuaj yeem tiv taus qhov kub thiab txias. Lawv feem ntau siv rau hauv kev tsim cov khoom siv los txo cov hluav taws xob hauv cov khoom siv hluav taws xob siab. Aramid ntawv muaj cov khoom zoo rwb thaiv tsev tom qab impregnated nrog insulating xim, thiab yog siv los ua ib qho khoom siv rwb thaiv tsev rau cov cua sov-resistant motors thaum ua ke nrog ntuj mica nplooj.
