Cov pa roj carbon fiber reinforced pob zeb (CFRP) yog siv los txhawb cov pob zeb ua vaj tse.
Nyob rau hauv lub tshav pob ntawm civil engineering, ib txoj kev tshiab thiab high-tech reinforcement yog npaj. Piv nrog rau cov txheej txheem kev txhawb nqa ib txwm muaj, txoj kev txhawb nqa no muaj kev tshawb fawb siab, kev nyiam thiab daim ntawv thov tus nqi thiab cov txiaj ntsig zoo rau kev sib raug zoo thiab kev lag luam. Cov pob zeb ua vaj tse ntxiv dag zog los ntawmcarbon fiber ntawvyog tsim los ntawm pob zeb, steel bar thiab carbon fiber ntawv. Composite kev nyuaj siab system, uas coj mus rau pem hauv ntej ntau yam tshiab teeb meem rau kev tsim kho qhov cuab lub zog, xws li bearing muaj peev xwm, stiffness xam, structural tsis ua hauj lwm hom thiab fiber sheet reinforcement mechanism, thiab lwm yam. Cov no yog cov ntsiab lus tseem ceeb uas yuav tsum tau daws. Nws muaj qhov tseem ceeb ntawm qhov tseem ceeb rau kev suav cov qauv thiab kev tsim kho engineering. Los ntawm kev hloov qhov ntev ntawm kev sib txuas, qhov siab thiab qhov sib piv ntawm CFRP daim ntawv, qhov kev siv lub zog, kev ua haujlwm tsis ua haujlwm ntawm kev sib tshuam, khoov muaj peev xwm thiab kev ua kom muaj zog ntawm CFRP daim ntawv ntxiv dag zog rau cov kab teeb pom kev zoo.
Qhov kawg ntawm cov kabmob muaj peev xwm ntawm cov kab teeb ci tuaj yeem txhim kho los ntawm kev ua cov ntawv CFRP nyob rau hauv qhov nro ntawm cov kab teeb ci, thiab qhov kawg ntawm cov kabmob muaj peev xwm tuaj yeem nce los ntawm qhov sib txawv ntawm cov ntawv CFRP.
Thaum lub sij hawm kuaj, tag nrho cov kab teeb pom kev pom tseeb khoov kab nrib pleb thiab shear tawg. Cov kab nrib pleb ntawm cov kab teeb uas tsis muaj zog tau tshwm sim ua ntej. Thaum cov kab nrib pleb nthuav dav dua, cov kab nrib pleb tsawg dua, thiab cov kab nrib pleb tau dav dua. Thaum lub steel bar yielded, cov kab nrib pleb nthuav dav sai, lub deflection ntawm cov kab teeb tau nce sai, tab sis lub peev xwm ntawm cov kab hluav taws xob muaj zog tau nce tsawg heev. Thaum lub sij hawm thauj khoom, cov kab nrib pleb tshwm tuaj lig thiab nthuav dav zuj zus.Muaj ntau cov kab nrib pleb. Ntxiv mus, cov kab nrib pleb ntxiv dag zog nrog fiberboard yog ncua thiab qhov pib tawg ntawm qhov pib load yog siab dua li ntawm cov kab hluav taws xob ntxiv zog tsis muaj fiber ntau.
