Cov khoom siv roj carbon fiber ntau tau nce rau hauv ntau lub teb xws li aerospace thiab aviation vim lawv lub cev nyhav thiab kub kub. Tsis ntev los no, R & D Center ntawm Tuam Tshoj Academy Tawm Tsav Tsheb Technology thiab Harbin Lub Tsev Kawm Ntawv ntawm Technology tau tsim ib qho tshiab ntawm graphene nano-reinforced cov ntaub ntawv tshiab. Raws li cov tshuaj carbon fiber ntau, cov khoom siv dag zog ntawm cov khoom tau nce ntau dua 10%, qhib lub kiv puag ncig hauv cov roj ntau ntawm composites.
Raws li Wu Di, tus thawj coj ntawm tes, tus graphene nano-reinforced tshiab cov khoom siv yog ntxiv nano-scale graphene rau cov roj fiber ntau cov khoom kom ntxiv tau zoo rau lub zog, lub zog thiab rigidity ntawm cov roj fiber ntau khoom. Muab piv rau cov khoom siv roj khov ntawm cov cim tshuaj, ntxiv rau qhov kev txhim kho ntawm cov khoom siv dag zog, nws kuj muaj cov khoom siv hluav taws xob, electromagnetic shielding thiab cov dej noo thiab dej tsis ua haujlwm.
Cov khoom siv ntawm cov khoom siv yog pom meej tshaj rau cov khoom ua ke, thiab muaj peev xwm ua kom tsis txhob muaj qhov teeb meem uas cov khoom siv sib xyaw thiab cov khoom siv hlau tau yooj yim los ua hluav taws xob ua hluav taws xob, uas tuaj yeem txhim kho lub zog ntawm qhov khoom; cov khoom siv sib xyaw tshiab Nws muaj ib tug zoo electromagnetic shielding muaj nuj nqi thiab yuav siv tau los npaj cov cuab yeej khoom siv vaj tse. Muab piv nrog cov khoom siv hlau, nws tuaj yeem tiv thaiv cov khoom hluav taws xob hauv hluav taws xob los ntawm electromagnetic hluav taws xob thiab ua kom txo tau qhov hnyav nce. Nws muaj cov khoom muaj zog hydrophobic thiab tuaj yeem siv los npaj cov dej ruaj khov, ua kom lub zog adaptability ntawm cov khoom, thiab muab kev txhawb nqa rau lub sij hawm ntev thiab qhov ua kom muaj cov khoom nyob rau hauv cov dej ntub.
Nano-muaj zog dua kev ua qauv ua ib txoj hauv kev tseem ceeb uas yuav ua rau kev ua tau zoo ntawm cov ntaub ntawv yog ib qho kev tshawb nrhiav nyob hauv thaj tsam ntawm cov ntaub ntawv nyob rau hauv xyoo tas los. Cov kev xyaum yog siv cov nanotubes ua ib qho qauv siv, tiam sis hom no muaj ntau txoj kev siv zog thiab cov kev txwv. Qhov teeb meem tseem ceeb tshaj plaws yog tias carbon nanotubes muaj zog fluidity, yooj yim los tsim "agglomeration" phenomenon, thiab material uniformity. Txom nyem, nws yog qhov nyuaj ua kom cov ntaub ntawv loj, thiab cov ntaub ntawv zoo nkauj yog me me thiab nquag tawg.
Graphene nano-reinforced tshiab composite khoom sib koom tsim los ntawm R & D chaw thiab Harbin Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb yog siv graphene daim txhuam cev los ntawm kev siv graphene oxide ua khoom. Cov duab kos daim duab muaj qhov loj hlob ntawm peb sab thiab muaj kev sib txuas kom sib npaug nrog cov roj carbon fiber ntau. Yog hais tias daim duab kos daim duab no zoo li lub cev "pob txha" ntawm tib neeg lub cev, ces cov khoom siv roj carbon fiber ntau yog "leeg", thiab ob tug muaj fused ua ke, yog li qhov tsis sib luag thiab sib luag ntawm cov khoom yeej zoo heev.
