Qhov sib txawv tseem ceeb ntawm CFRP thiab GFRP yog tias CFRP muaj cov pa roj carbon raws li cov khoom siv fiber ntau, qhov GFRP muaj iav ua cov khoom siv fiber ntau.
Lo lus FRP yog hais txog fiber ntau cov yas. Cov no yog cov polymers uas tuaj yeem hu ua cov ntaub ntawv sib xyaw, uas yog ua los ntawm polymer matrix uas tau ntxiv nrog fiber ntau. Cov khoom siv txhawb zog sib txawv ntawm ib qho yas mus rau lwm qhov. Piv txwv li, nyob rau hauv fiberglass, cov khoom siv ntxiv yog iav; Hauv CFRP, cov khoom siv txhawb zog yog cov pa roj carbon, thiab lwm yam. CFRP thiab GFRP yog ob hom fiber ntau cov khoom siv yas.
CFRP yog dab tsi?
Lub sij hawm CFRP sawv cev rau carbon fiber reinforced yas. Cov no yog cov muaj zog polymer cov khoom sib xyaw uas muaj lub teeb yuag thiab lub zog siab. Yog li, cov ntaub ntawv no tseem ceeb hauv kev tsim cov khoom sib txawv uas peb siv hauv peb lub neej txhua hnub. CFRP yog cov khoom siv sib xyaw uas tau txhawb nqa siv cov pa roj carbon fiber ntau raws li cov txheej txheem tseem ceeb.
Feem ntau, CFRPs yog cov thermosetting resins xws li epoxy, polyester lossis yas ester. Txawm hais tias CFRP muaj qhov hnyav heev thiab qhov ntom ntom, lawv muaj zog dua thiab khov kho rau ib chav tsev qhov hnyav ntawm cov khoom.
Daim duab 01: Kev puas tsuaj hauv CFRP Cov Khoom
Txawm li cas los xij, muaj qee qhov tsis zoo ntawm kev siv cov khoom siv CFRP. Ib tug loj drawback yog nws cov nqi. Qhov no yog vim li cas CFRP tsis siv ntau npaum li ntawd. Tus nqi ntawm cov khoom sib txawv nyob ntawm qhov kev lag luam tam sim no, hom carbon fiber ntau siv los txhawb, thiab fiber ntau rau qhov loj. Feem ntau, CFRP yog kim, nyob ib ncig ntawm 5 mus rau 25 npaug ntawm fiberglass. Lwm yam tshaj li tus nqi, conductivity yog lwm qhov tsis zoo ntawm CFRP vim tias cov pa roj carbon fiber ntau yog cov conductive (fiberglass yog insulative). Txawm li cas los xij, cov cuab yeej no tuaj yeem ua tau zoo thiab tsis zoo nyob rau qee lub sijhawm.
GFRP yog dab tsi?
Lub sij hawm GFRP sawv cev rau iav fiber reinforced yas. Cov khoom siv no muaj iav ua cov khoom siv ntxiv rau cov polymer matrix. Piv nrog rau lwm cov ntaub ntawv ntawm FRP, iav fiber reinforced yas muaj qhov sib piv ntawm qhov hnyav thiab qhov hnyav nruab nrab. Nws kuj yog cov khoom siv muaj zog. Ntxiv rau cov no, GFRP tsis tshua kim, uas tso cai rau peb siv cov khoom no hauv ntau daim ntawv thov.
Daim duab 02: Npuag ua los ntawm GFRP
Feem ntau, lub tshuab nqus tsev manifolds yog tsim los ntawm cov khoom siv GFRP. Qhov zoo ntawm kev siv cov khoom siv no suav nrog qhov txo qhov hnyav txog li 60%, txhim kho qhov zoo thiab aerodynamics, txo cov khoom los ntawm kev sib txuas, muaj peev xwm tsim tau rau hauv cov pwm yooj yim, thiab lwm yam. Tsis tas li ntawd, fiber ntau tuaj yeem muab tso rau hauv cov kev taw qhia sib txawv rau tiv taus kev ntxhov siab, uas ua rau muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv GFRP.
Qhov txawv ntawm CFRP thiab GFRP yog dab tsi?
CFRP thiab GFRP yog ob hom fiber ntau cov khoom siv. Qhov sib txawv tseem ceeb ntawm CFRP thiab GFRP yog tias CFRP muaj cov pa roj carbon raws li cov khoom siv fiber ntau, qhov GFRP muaj iav ua cov fiber ntau.
Hais txog cov khoom, qhov sib txawv ntawm CFRP thiab GFRP yog tias CFRP yog qhov hnyav thiab muaj qhov ntom ntom, thaum GFRP muaj qhov hnyav nruab nrab thiab nruab nrab ntom. Ntxiv mus, CFRP yog kim heev, uas txwv tsis pub siv cov khoom no hauv ntau daim ntawv thov. Lub caij no, sib piv, GFRP tsis tshua kim thiab siv qhov twg CFRP siv tsis tau.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm CFRP thiab GFRP hauv daim ntawv teev npe.
Summary – CFRP vs GFRP
FRP lossis fiber reinforced yas yog cov khoom siv polymer uas muaj cov khoom siv polymer ntxiv nrog rau lwm cov khoom. CFRP thiab GFRP yog ob hom khoom siv fiber ntau. Qhov sib txawv tseem ceeb ntawm CFRP thiab GFRP yog tias CFRP muaj cov pa roj carbon raws li cov khoom siv fiber ntau, qhov GFRP muaj iav ua cov fiber ntau.
