Dab tsi yog qhov hardness ntawm carbon fiber piv rau hlau? Puas yog carbon fiber ntau yooj yim tawg?
Kev lees paub dav dav ntawm carbon fiber los ntawm nws cov ntawv thov thawj zaug rau niaj hnub no feem ntau yog vim nws qhov kev ua tau zoo, tshwj xeeb tshaj yog nws lub teeb yuag. Hauv ntau qhov kev lag luam, carbon fiber tau nyiam rau nws lub zog thiab kav ntev. Cov pa roj carbon fiber ntau npaum li cas, thiab nws puas yooj yim tawg? Muaj pes tsawg zaus nyuaj dua carbon fiber piv rau hlau?
Cov pa roj carbon fiber ntau yog yim zaug nyuaj dua li cov hlau hauv cov ntsiab lus ntawm lub zog. Nws yog cov khoom siv fiber ntau nrog cov ntsiab lus siab carbon ntau dua 95%. Nws muaj lub zog tensile txog li 3500 MPa thiab lub tensile modulus ntawm 250 GPa, qhia superior zog ua tau zoo piv rau ib txwm steel. Lub zog siab no yog qhov laj thawj tseem ceeb vim li cas carbon fiber tuaj yeem hloov cov hlau ib txwm nyob hauv ntau qhov chaw.
Thaum nws los txog rau qhov yooj yim ntawm kev tawg, carbon fiber strands, tshwj xeeb tshaj yog ib tus neeg fibers, tuaj yeem tawg tau yooj yim vim lawv nyias nyias dua li tib neeg cov plaub hau. Txawm li cas los xij, steel strands ntawm qhov loj me me kuj yuav yooj yim tawg. Lub siab axial lub zog ntawm carbon fiber strands ua rau lawv raug puas tsuaj nyob rau hauv lub lateral quab yuam, uas ua rau muaj kev nkag siab tias carbon fiber ntau yuav tawg.
Hauv cov khoom siv roj carbon fiber ntau, ntau txhiab cov pa roj carbon fiber ntau txuas ntxiv tau ua ke siv cov khoom siv matrix thiab muab tso rau ntawm cov ces kaum sib txawv kom ua tiav siab khoov modulus. Yog tias cov khoom no raug thauj khoom ntau tshaj lawv cov qauv txwv, nws yuav ua rau ib feem ntawm cov pa roj carbon fiber ntau tsis ua tiav. Cov cuab yeej no yog vim li cas cov khoom siv carbon fiber tau siv rau hauv kev siv tsheb sib tsoo lub zog nqus.
