Lub teeb yuag ntawm lub cev tsheb feem ntau pib los ntawm ob yam: lub cev qauv tsim thiab xaiv cov khoom siv thiab hloov pauv. Nyob rau hauv cov nqe lus ntawm cov khoom siv lightweighting, high-strength steel, magnesium, aluminium thiab yas tseem siv los ua cov khoom tseem ceeb ntawm tsheb sib txuas. Ntawm lawv, carbon fiber yog qhov zoo tshaj plaws, thiab nws cov txiaj ntsig tuaj yeem hloov pauv cov ntaub ntawv hlau. Ntawm lawv, kev siv cov ntaub ntawv sib xyaw nrog cov resin thiab hlau raws li cov matrix ntawm lub tsheb lub cev yog qhov paub tab thiab muaj ntau yam zoo hauv lub cev tsim khoom.
1. Muaj lub zog siab. Cov ntaub ntawv carbon fiber ntau muaj qhov tshwj xeeb tshaj plaws modulus thiab lub zog tshwj xeeb ntawm cov khoom siv tam sim no. Thaum siv los ua cov khoom siv nrog tib lub zog thiab nruj li cov hlau muaj zog, qhov hnyav tuaj yeem txo tau li ntawm 70%.
2. Muaj kev qaug zog zoo. Carbon fiber ntau composites muaj kev qaug zog zoo heev. Txij li thaum tawg nyob rau hauv qaug zog load yog tshwm sim los ntawm sab hauv tawg expansion nyob rau hauv cov khoom, lub interface ntawm carbon fiber thiab matrix nyob rau hauv carbon fiber composite cov ntaub ntawv yuav zoo tiv thaiv kom txhob qaug zog tawg expansion, thiab sab nraud load yog borne los ntawm lub reinforced fibers. Yog li ntawd, lub zog qaug zog txwv yog siab dua li cov khoom siv hlau thiab lwm yam khoom siv. Cov ntaub ntawv tsis yog xim hlau yog ntau dua.
3. Kev sib tsoo zoo zog nqus. Cov khoom siv carbon fiber ntau yog qhov zoo tshaj plaws hloov pauv rau cov khoom siv hlau tsheb. Lub zog nqus tus nqi hauv kev sib tsoo yog 4 mus rau 5 npaug ntawm txhuas thiab hlau. Nws tuaj yeem txo qhov loj ntawm lub tsheb lub cev thaum ua kom tsis muaj qhov poob ntawm lub zog los yog nruj thiab tswj kev ua haujlwm ntawm kev sib tsoo. Zoo heev txo qhov kev pheej hmoo ntawm kev txo tsheb kev nyab xeeb los ntawm kev sib sib zog nqus.
4. Kev tsim khoom zoo. Cov khoom siv carbon fiber ntau muaj cov khoom siv tes ua zoo thiab tsim qauv. Los ntawm kev kho cov duab, kev npaj, thiab cov ntsiab lus ntawm CFRP cov ntaub ntawv, lub zog, nruj thiab lwm yam kev ua tau zoo ntawm cov khoom tuaj yeem ua tiav. Cheebtsam uas tuaj yeem tsim nrog pwm tuaj yeem tsim nyob rau hauv ib qho mus, txo cov fasteners thiab cov pob qij txha tuaj yeem txhim kho cov khoom siv zoo.
