Puas tuaj yeem carbon fiber ntau xeb?
Cov pa roj carbon fiber ntau yog chemically ruaj khov, corrosion-resistant, thiab yuav tsis xeb. Tias yog vim li cas nws ua haujlwm zoo nyob rau hauv ib puag ncig hnyav. Tab sis muaj zog oxidizing tus neeg sawv cev, xws li hydrogen peroxide lossis sulfuric acid, yuav cuam tshuam rau nws.
Ib yam li ntawd, epoxy resin yog inert thiab yuav tsis xeb los yog corrode. Txawm li cas los xij, nws yog rhiab heev rau hnub ci. Yog li, npog cov pa roj carbon fiber ntau nrog UV resistant tag kom tiv thaiv kev puas tsuaj mus ntev los ntawm tshav ntuj.
Nws tsim nyog sau cia tias carbon fiber ntau tuaj yeem ua rau galvanic corrosion thaum sib cuag nrog qee cov hlau. Txawm hais tias nws yuav tsis ua rau pom tseeb nto corrosion nyob rau lub sijhawm luv luv, cov khoom siv corrosion ntxiv thiab ua rau kev puas tsuaj nrog lub sijhawm. Hmoov zoo, qhov no xav tau cov xwm txheej tshwj xeeb, thiab qee cov txheej txheem muaj kev tiv thaiv.
Puas tuaj yeem Carbon Fiber Break?
Cov lus teb luv luv yog yog. Txhua yam khoom tuaj yeem ua tsis tiav, tab sis nws nyuaj me ntsis dua qhov ntawd. Ntau yam, xws li cov txheej txheem tsim khoom, tsim, thiab siv, cuam tshuam rau kev ua haujlwm ntev.
Piv txwv li, qhov khoob tuaj yeem tsim tau, thiab nws yuav ua rau tawg yog tias cov chaw tsim khoom siv cov resin tsis sib npaug lossis tsis siv txaus. Nyob rau tib lub sijhawm, cov kab nrib pleb me me no tuaj yeem kis mus txog thaum nws tawg. Txawm tias muaj kev cuam tshuam me me tuaj yeem ua rau ua tsis tiav.
Kev taw qhia ntawm cov fibers thiab cov khaubncaws sab nraud povtseg kuj tseem muaj txiaj ntsig zoo rau kev qaug zog. Raws li hom kev quab yuam koj thov. Compression, shear, thiab nro quab yuam ua rau ntau hom kev ua tsis tiav.
Lub woven fiber nyob rau hauv ib tug 0 degree layup muaj tsawg torsional zog tshaj ntawm 45 degree, piv txwv li. Yog li nws yuav tawg yog tias koj twist nws.
Cov kab hauv qab yog tias koj nyob hauv qab qhov chaw thauj khoom rau ib feem, nws yuav tsis tawg yooj yim.
Tsis tas li ntawd, nco ntsoov tias nws nyuaj rau kev txheeb xyuas cov cim ntawm kev puas tsuaj uas qhia tias yuav ua tsis tiav. Thiab tsis zoo li lwm cov ntaub ntawv uas khoov lossis buckle, thaum carbon fiber tsis ua haujlwm, nws tuaj yeem ua tsis tau zoo thiab tawg.

Cov huab cua puas cuam tshuam rau lub neej ntev ntawm carbon fiber?
Cov pa roj carbon fiber ntau muaj qhov thermal expansion. Yog li, nws cov duab, cheeb tsam, ntim, lossis qhov ntom ntom tsis hloov ntau hauv cov lus teb rau qhov kub thiab txias. Qhov ntawd tsis tau txhais hais tias nws tiv thaiv qhov tshwm sim ntawm huab cua hauv lub sijhawm ntev. Cov kev tshawb fawb pom tias kev sib xyaw ntawm huab cua tej zaum yuav muaj kev cuam tshuam rau cov pa roj carbon fiber ntau hauv cov chaw sib txawv.
Freeze-Thaw Cycles
Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Txog Kev Tshawb Fawb Kev Tshawb Fawb tau txheeb xyuas lub voj voog khov-thaw li qhov ua tau hem thawj rau carbon fiber ntau. Tsis tas li ntawd, lawv pom cov dej khov-thaw degrade carbon fiber reinforced pob zeb ntau dua hauv dej qab ntsev.
Nws tsis tas yuav cov carbon fiber uas poob kev ncaj ncees tab sis yog microcracks tsim hauv matrix thiab fiber ntau / matrix debonding. Thiab cov teebmeem yog ib feem vim tias cov txheej txheem nplaum tsis zoo li lwm cov carbon fiber siv.
Thaum kawg, txawm tias cov teebmeem no, lwm txoj kev tshawb fawb pom tau tias carbon fiber reinforced pob zeb ntau ruaj dua li cov qauv pob zeb.
Hygrothermal Aging
Hygrothermal aging tej zaum yuav muaj kev cuam tshuam rau kev ua haujlwm ntawm cov pa roj carbon fiber ntau hauv qee qhov kev siv tab sis tsis yog lwm tus.
hygrothermal aging yog dab tsi? Hygrothermal aging yog hais txog kev sib xyaw ua ke ntawm cov cua sov thiab cov dej noo thiab nws cuam tshuam dab tsi ntawm cov qauv.
Kev raug tshav kub thiab ya raws ntev yuav muaj kev cuam tshuam me ntsis rau lub zog flexural ntawm carbon fiber. Tab sis nyob rau hauv kev ruaj ntseg load thiab nyob rau hauv lub xub ntiag ntawm dej ntsev, lub tensile lub zog txo ntawm 7% thiab 12%.
