       Cov pa roj carbon fiber yog lub teeb hauv qhov hnyav, tab sis muaj zog heev, thiab muaj qee yam zoo hauv kev cuam tshuam, kev tiv thaiv corrosion, thiab electromagnetic shielding. Cov pa roj carbon fiber ntau yog cov khoom siv anisotropic, thiab nws cov fibers nyob rau hauv cov lus qhia sib luag thiab ntsug muaj cov khoom sib txawv. Txhawm rau ua kom cov khoom ua haujlwm ruaj khov, cov khoom siv carbon fiber ntau yuav tsum tau muab tso ua ntej yuav kho los ntawm kev kub nias.

       Lub nteg-up tsim ntawm cov khoom siv fiber ntau yog feem ntau suav hais tias yog los ntawm peb yam ntawm nteg lub kaum sab xis, tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab txheej txheej txheej txheej, thiab tom qab ntawd ua ke nrog kev siv cov khoom siv los txiav txim qhov zoo tshaj plaws. lay-up scheme ntawm cov khoom. Tsis tas li ntawd, kev tsim khoom ntawm cov kws tshaj lij kuj tseem ceeb dua. Boshi carbon fiber ntau cov kws tshaj lij muaj ntau tshaj kaum xyoo ntawm kev tsim kho kev tsim khoom, thiab tuaj yeem tswj hwm qhov tsis sib xws ntawm txhua qhov txuas hauv kev tsim layup thiab tom qab ua tiav, thiaj li ua kom cov khoom zoo. zoo.

       Qhov loj ntawm carbon fiber prepreg yuav tsum tau txiav raws li qhov loj thiab tuab ntawm cov khoom carbon fiber ntau, thiab tom qab ntawd qhov txiav prepreg yog nteg. Lub layup yuav tsum coj mus rau hauv tus account qhov kev sib raug zoo ntawm cov pa roj carbon fiber txoj kev thiab lub ntsiab kev nyuaj siab, thiab nqa tawm cov coj layup ua ke nrog cov carbon fiber txoj kev. Yog hais tias kev sib raug zoo ntawm layup thiab kev ntxhov siab nyob rau hauv ib txwm muaj xwm txheej yog 45 ° layup, cov kev taw qhia ntawm kev nyuaj siab yog 45 °, nws yog tsim nyog los xyuas kom meej tias lub layup ntawm fibers nyob rau hauv cov kev taw qhia no ntau npaum li cas. Yog tias nws yog 90 ° layup, tib yam yog qhov tseeb, yog li ntawd cov txheej txheem no kuj zoo ib yam nrog 90 °.

        Qhov sib txawv layup lub kaum sab xis coj txog cov khoom sib txawv. Hauv cov khoom lag luam tiag tiag, 0 °, ± 45 °, thiab 90 ° yog ntau dua. ± 45 ° layup tuaj yeem txhim kho kev ruaj ntseg ntawm cov khoom siv fiber ntau. Tau kawg, hauv kev siv tiag tiag, ntau yam kev xav yuav tsum tau txiav txim siab. Piv txwv li, thaum 0 ° yog sab nraud, qhov kev ntxhov siab zoo dua li thaum ± 45 ° fiber ntau nyob rau sab nraud. Nws yog qhov pom tseeb dua, yog li koj yuav tsum sim xaiv cov txheej txheem rov qab, thiaj li ua kom muaj kev ruaj ntseg ntawm cov khoom siv carbon fiber ntau.

       Cov saum toj no yog kev txhais lus ntawm cov ntsiab lus hauv kev tsim cov khoom siv carbon fiber ntau layup. Tus tsim ntawm lub layup yeej txiav txim siab tag nrho cov khoom ua tau zoo ntawm cov khoom siv carbon fiber. Yog li ntawd, yuav tsum tau them tshwj xeeb mloog thaum lub sij hawm tso txheej txheem, thiab pre-compaction yuav tsum tau tom qab cov khoom nteg tiav. kev ua kom paub tseeb layup zoo.
