Qhov zoo ntawm cov pa roj carbon fiber ntau precursor filaments tsim lawv los ua cov khoom siv tseem ceeb thoob plaws hauv kev lag luam xws li aerospace, lub zog tshiab, kev tsim khoom siab - kawg, thiab "tsawg- kev lag luam siab." Tsis tas li ntawd, Tuam Tshoj txoj kev ua tiav tsis ntev los no hauv T1200- qib precursor filaments thiab loj-tw technologies tau nrawm rau kev paub txog kev tswj hwm ywj pheej thiab loj- teev daim ntawv thov rau kev tsim cov pa roj carbon fiber ntau hauv tsev.
Siab zog thiab siab Modulus
Tensile zog tuaj yeem ncav cuag 5 mus rau 10 npaug ntawm cov hlau; Piv txwv li, engineering-qib tensile lub zog ntawm T1200-chav kawm carbon fiber nce mus txog 7,566 MPa, nrog rau qhov ntsuas qhov siab tshaj plaws mus txog 8,056 MPa.
High modulus: tshwj xeeb tshaj yog, suab -raws li precursor filaments tuaj yeem ua tiav qhov ultra- siab modulus tom qab graphitization, ua rau lawv haum rau aerospace structural Cheebtsam uas yuav tsum tau nruj nruj heev.
Siab -Tsub Resistance thiab Thermal Stability
Muaj peev xwm tiv taus qhov kub siab tshaj 2000℃hauv qhov chaw inert tsis muaj melting lossis softening.
Nws muaj cov coefficient tsawg heev ntawm thermal expansion- uas tuaj yeem ua rau tsis zoo (xws li, hauv suab -raws li carbon fibers)- ua rau nws haum rau siv nyob rau hauv huab cua kub.
Lub teeb yuag thiab tsawg ntom ntom
Cov pa roj carbon fiber ntau muaj qhov ceev ntawm 1.5–2.0 g / cm³-tsuas yog ib qho -quarter ntawm cov hlau thiab ib nrab ntawm aluminium alloy- txo qhov hnyav ntawm cov khoom kawg thiab txhim kho lub zog efficiency.
Corrosion Resistance thiab Chemical Stability
Cov tshuaj tiv thaiv zoo heev rau ib puag ncig uas muaj cov kua qaub, alkalis, ntsev tsuag, thiab cov neeg ua haujlwm zoo sib xws; qhia tias tsis muaj kev hloov pauv tseem ceeb txawm tias tom qab immersion hauv aqua regia.
Haum rau siv nyob rau hauv corrosive ib puag ncig hauv marine, tshuaj, thiab aerospace industries.
