Cov pa roj carbon fiber muaj npe nrov rau nws qhov tshwj xeeb siab - kub thiab corrosion kuj, tau txais nws lub npe xws li "King of New Materials" thiab "Dub Kub." Nrog rau qhov ntom ntom tsawg dua li ib-lub quarter ntawm cov hlau tsis tau muaj zog ntau dua xya mus rau cuaj npaug, nws embodies ib qho kev sib xyaw ua ke ntawm rigidity thiab saj zawg zog -muaj qhov pliability ntawm fiber ntau thaum nyuaj dua hlau, txawm tias zoo li tib neeg cov plaub hau. Niaj hnub no, cov khoom lag luam zoo tshaj plaws no tau txav mus dhau qhov chaw sim thiab mus rau qhov siab - qhov kawg kev tsim khoom lag luam, suav nrog aerospace, kev tiv thaiv hauv tebchaws, kev tsheb ciav hlau, lub zog tshiab, kev lag luam qis - qhov siab, thiab humanoid robotics.
Raws li kev txheeb cais los ntawm Tuam Tshoj Chemical Fibers Association, Tuam Tshoj cov pa roj carbon fiber ntau tau khaws cia qhov nruab nrab txhua xyoo kev loj hlob ntawm ntau dua 30% nyob rau lub sijhawm "14th Tsib-Xyoo Plan". Tam sim no, Tuam Tshoj suav txog kwv yees li 50% ntawm lub ntiaj teb tag nrho cov pa roj carbon fiber ntau tsim muaj peev xwm, ruaj khov ua ntej hauv ntiaj teb.
Cov tuam txhab suav tseem ceeb suav nrog Zhongfu Shenying, Jilin Chemical Fiber, Guangwei Composites, Zhongjian Technology, Shanghai Petrochemical, Hengshen Co., Ltd., Xinchuang Carbon Valley, Guotai Dacheng, thiab Changsheng Technology.
**Mass Production ntawm T1000-Qib Me-Tow Carbon Fiber Ua tiav**
Thaum Lub Rau Hli 2, Sinopec Shanghai Petrochemical, koom tes nrog Shanghai Research Institute of Petrochemical Technology, tau ua tiav cov thev naus laus zis tseem ceeb rau kev tsim cov ntub dej -spun T1000- qib siab - carbon fiber ntau thiab ua tiav cov khoom loj. Qhov no yog qhov tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm cov pa roj carbon fiber ntau.
Lub siab -kev ua tau zoo carbon fiber tau ua tiav thiab loj- tsim tawm ntawm no yog ntawm "12K me-tow" ntau yam. Yooj yim muab, txhua tus cab muaj 12,000 tus neeg filaments. Txawm li cas los xij, tsis txhob kwv yees nws lub zog raws li nws txoj kev zoo nkauj; ib tug cab kuj boasts lub tensile zog tshaj 6.5 GPa thiab ib tug tensile modulus tshaj 300 GPa -muaj peev xwm rub tau ib tug nruab nrab- tsheb loj hnyav kwv yees li 10 tons.
Lub sijhawm no, tej zaum koj yuav xav tsis thoob: qhov "K" thiab "T" sawv cev rau dab tsi?
** Tswv yim ceev:** Carbon fibers yog categorized los ntawm cab loj rau hauv "loj-tow" thiab "me-tow" hom. Hauv kev lag luam, "K" feem ntau yog siv los txheeb xyuas cov lus qhia tshwj xeeb (qhov twg 1K sib npaug 1,000 tus neeg filaments).
Cov pa roj carbon fibers nyob ntawm 24K lossis qis dua yog cais raws li "me me-tow." Cov yeeb yam no zoo nkauj dua, kev ua tau zoo dua qub, thiab siab dua, ua rau lawv zoo tagnrho rau kev ua haujlwm siab - xws li aerospace thiab kev tsim khoom siab heev. Cov pa roj carbon fiber ntau nrog tus cab loj ntawm 48K lossis siab dua yog cais raws li "loj-tow" carbon fiber. Piv rau me me -tw variants, qhov zoo ntawm cov loj -cov pa roj carbon fiber ntau yog siab dua ib qho - kab tso zis thiab qis dua cov nqi tsim khoom raws li kev tsim khoom zoo ib yam; nws ua haujlwm raws li cov khoom tseem ceeb uas txhawb nqa loj - daim ntawv teev npe hauv kev lag luam xws li cua zog thiab lub zog cia.
Tus lej tom qab lub npe "T" ncaj qha mus rau qib tensile zog; tus lej siab dua qhia tau tias kev ua tau zoo dua.

Ntiaj teb no debut ntawm Tuam Tshoj tus kheej tsim T1200-qib ultra-high-strength carbon fiber
Thaum Lub Peb Hlis 11, Zhongfu Shenying- cov pa roj carbon fiber ntau R&D thiab cov chaw tsim khoom lag luam ntawm Tuam Tshoj National Building Material Group (CNBM)- tau tshaj tawm nws tus kheej tsim T1200- qib ultra- siab- lub zog carbon fiber thoob ntiaj teb. Cov khoom lag luam tau ua tiav engineering- nplai ntau lawm, nrog lub peev xwm mus txog qib pua-tuj.

T1200-qib ultra- siab- cov pa roj carbon fiber ntau tau ua tiav kev ua haujlwm- nplai tensile zog tshaj 8,000 MPa, ua rau lub ntiaj teb thawj T1200- qib carbon fiber khoom kom ncav cuag qib ntawm kev tsim khoom loj. Qhov kev ua txhaum loj no qhia tau tias Tuam Tshoj tau ua tiav tag nrho -chain ywj pheej tswj- ncua kev siv thev naus laus zis, khoom siv, thiab kev hloov pauv los ntawm kev tshawb fawb hauv chav kuaj mus rau engineering- nplai ntau lawm-hauv kev ua haujlwm siab carbon fiber.
