Lub zog ntawm cov khoom siv ntawm cov composites yog pawg los ntawm cov fibers. Qhov no txhais tau tias thaum cov resins thiab cov fibers tau sib xyaw ua ke, lawv cov peev xwm zoo heev rau cov neeg ntawm tus neeg ntawm tus neeg. Cov ntaub ntawv ntsuam xyuas qhia tau tias cov khoom siv siv hluav taws xob fiber ntau yog cov khoom sib xyaw uas muaj cov khoom siv feem ntau. Yog li ntawd, cov ntaub npuag yog qhov tseem ceeb thaum tsim qauv sib xyaw.
Pib cov txheej txheem los ntawm kev txiav txim siab hom cuab tam xav tau rau koj qhov project. Lub chaw tsim khoom lag luam raug xaiv tau los ntawm peb hom kev txhawb ntxiv: iav fiber ntau, carbon fiber ntau, carbon fiber ntau thiab kev muag khoom (aramid fiber). Iav Fiber yeej yog qhov kev xaiv thoob ntiaj teb, thaum carbon fick muaj siab tawv me thiab kevat® tsis kam ua. Nco ntsoov tias cov ntaub npuag tuaj yeem ua ke hauv laminates tsim cov khoom hybrid stacks uas muab cov txiaj ntsig ntawm ntau tshaj ib cov khoom.
Fiberglass Reubplies
Fiberglass yog cov khoom siv uas paub. Fiberglass yog lub hauv paus ntawm kev sib xyaw kev lag luam. Nws tau siv nyob rau hauv ntau daim ntawv thov sib xyaw txij li xyoo 1950 thiab nws lub cev lub zog tau to taub zoo. Cov fiberglass yog lub teeb yuag, muaj cov tensile me ntsis thiab lub zog compressive, tuaj yeem tiv thaiv kev puas tsuaj thiab siv tau yooj yim. Cov khoom uas tawm ntawm kev tsim tau paub txog cov npe fiberglass txhawb nqa yas (frp). Nws yog ib txwm muaj nyob rau txhua thaj chaw ntawm lub neej. Qhov laj thawj yog vim li cas nws hu ua fiberglass yog vim tias hom fibered fiber ntau yog tsim los ntawm melting quartz thiab lwm yam khoom ore fementatures rau hauv lub khob slurry. Thiab tom qab ntawd rub tawm ntawm cov kev kub ceev filaments. Hom fiber no yog vim muaj pes tsawg leeg ntawm sib txawv muaj ntau yam hauv. Cov rwb thaiv tsev zoo. Thiab carbon fiber muaj qhov tsis zoo ib yam yog cov khoom lag luam muaj ntau nkig. Ductility tsis zoo. Tsis hnav-resistant. Tam sim no, rwb thaiv tsev, tso cua kub, tiv thaiv kev tiv thaiv corrosion yooj yim thiab ntau cov teb muaj kev siv cov iav fiber ntau txhawb nqa yas.
Fiberglass yog qhov feem ntau siv tau ntawm txhua yam muaj ntau. Qhov no yog feem ntau vim nws tus nqi qis thiab muaj zog rau lub cev. Fiberglass tau zoo rau cov haujlwm txhua hnub thiab cov seem uas tsis tas yuav xav tau cov ntaub fiber ntau ntxiv rau ntxiv lub zog thiab ua kom ntev.
Txhawm rau kom ua tiav lub zog ntawm cov fiberglass, nws tuaj yeem siv nrog epoxy resins thiab tuaj yeem kho tau siv cov qauv laminques. Nws yog qhov zoo haum rau cov ntawv thov hauv automotive, marine, tsim kho, tshuaj lom neeg thiab iberospace kev lag luam thiab feem ntau siv hauv cov khoom ntaus pob ncaws pob.
Aramid fiber ntau txhawb zog
Aramid Fiber yog ib co te te te tecect compound. Nws muaj lub zog siab, muaj lub zog kub, kev tiv thaiv corrosion, lub teeb deforance, thiab yog ib qho ntawm cov ntaub ntawv tseem ceeb hauv kev tiv thaiv kev lag luam. Muaj ntau cov ntawv thov hauv cov khoom siv cov khoom muag, cov khoom siv ya davhlau.
Aramid Fibers yog ib qho ntawm thawj lub high-zog hluavtaws fibers kom tau txais kev txais txiaj ntsig hauv Fiber-ReferCed plastics (FRP) kev lag luam. Composite qib para-aramid fibers yog lub teeb ci ntsa iab, muaj cov muaj zog tensile zoo heev, thiab raug suav hais tias muaj txiaj ntsig zoo rau kev cuam tshuam thiab kev puas tsuaj. Cov ntawv thov feem ntau suav nrog lub tsho poj niam xws li kayaks thiab canes, aircraft hnab looj tes thiab cov hnab looj tes siab, txiav hnab looj tes ua haujlwm, cov khoom lag luam siab, cov khoom lag luam tawm thiab ntau dua. Aramid Fibers yog siv nrog epoxy lossis vinyl ester resins.
Carbon Fiber txhawb
Nrog cov ntsiab lus carbon ntawm ntau tshaj 90%, carbon fiber muaj qhov kawg qhov kawg tensile lub zog hauv kev lag luam frp. Qhov tseeb, nws kuj tseem muaj cov kev lag luam kev lag luam zoo tshaj plaws thiab qhov ua tau zoo. Tom qab kev ua tiav, cov fibers no ua ke los ua cov roj fiber ntau ntxiv xws li cov ntaub thiab hmoov av. Carbon cov fiber ntau txhawb nqa lub zog muaj zog thiab nruj me ntsis, thiab feem ntau yog kim dua li lwm cov kev txhawb nqa fiber ntau dua li lwm cov kev txhawb nqa fiber ntau dua li lwm cov kev txhawb nqa.
Txhawm rau ua kom tiav lub zog ntawm carbon fiber, nws yuav tsum tau siv nrog epoxy resins thiab tuaj yeem kho tau siv cov qauv laminques. Nws yog qhov zoo haum rau kev siv tsheb, tubrog nkoj thiab ib daim ntawv thov aerospace thiab feem ntau siv hauv cov khoom lag luam ntaus pob.
