Tsis ntev los no, tom qab ntau xyoo ntawm kev mob siab rau kev tshawb fawb, Shanxi lub koom haum ntawm Coal Chemistry ntawm Tuam Tshoj Academy ntawm Sciences, koom tes nrog rau lwm yam units, tau ntse tsim domestically tsim T1000- qib high-kev ua tau zoo carbon fiber.
Qhov "super{0}}cov ntaub ntawv muaj zog" tam sim no nyob rau hauv ntau lawm. Txhua strand muaj 12,000 filaments, txhua txoj kab uas hla tsawg dua ib -feem kaum lub thickness ntawm tib neeg cov plaub hau, tseem muaj lub zog tensile siab heev. Ib qho -meter- ntev carbon fiber strand hnyav tsuas yog 0.5 grams, tab sis muaj lub zog tensile tshaj 6600 megapascals, muaj peev xwm nqa tau kwv yees li 200 kilograms yam tsis tau tawg-7 mus rau 8 npaug zog dua hlau.
Tus neeg sau xov xwm tau mus xyuas qhov chaw yug ntawm cov pa roj carbon fiber ntau thiab saib cov txheej txheem. Tom qab cov khoom sib xyaw ua ke yog polymerized, lawv tau ua tiav los ntawm kev qhuav - dav hlau ntub - spinning txoj kev los ua ib pob ntawm filaments. Cov pob khoom no zoo li daim kab xev pob tshab, tab sis nws muaj 4,000 filaments. Ob mus rau peb pob khoom yog twisted ua ke, thiab txhua qhov tshwm sim muaj 12,000 filaments.
Tam sim no, qhov "super{0}}cov ntaub ntawv muaj zog," hu ua "dub kub," tab tom tawm ntawm chav kuaj thiab dhau los ua "cov ntsiab lus tseem ceeb" rau kev lag luam hauv teb chaws xws li aerospace, kev tiv thaiv hauv teb chaws, lub zog tshiab, thiab siab - khoom tsim khoom kawg.
