Muaj ntau lub tswv yim yuav tsum tau xav txog thaum xaiv cov khoom siv hauv tsheb, xws li cov khoom siv dag zog, kev hnyav, cov khoom ruaj khov, cov khoom tsim, thiab kev ua haujlwm. Txhua yam yuav muaj feem cuam tshuam txog kev tsim, kev tsim khoom, kev muag khoom thiab kev siv ntawm lub tsheb. Nyob rau hauv xyoo tas los, Carbon Fiber Reinforced Polymers (CFRP) tau dhau los ua cov khoom siv tshiab nrog nws cov kev coj ua tshwj xeeb. Cov kab mob carbon fiber reinforced polymer matrix composites muaj cov nram qab no zoo dua lwm yam khoom siv hauv tsheb.
1. Cov khoom siv zoo heev
Cov carbon fiber reinforced resin matrix composite (CFRP) muaj qhov ceev ntawm 1.5 rau 2 g / cm3, uas yog tsuas yog 1/4 rau 1/5 ntawm cov pa roj carbon zoo, thiab yog li 1/3 ntais dua aluminium alloy, tab sis carbon fiber Cov khoom sib xyaw Cov khoom sib xyaw cuab yeej ua tau zoo dua li cov xim ntawm cov khoom siv hlau, thiab lub zog tensile yog 3 txog 4 npaug ntawm cov hlau. Lub zog ntawm cov hlau thiab aluminium yog 30% rau 50% ntawm lub zog tensile, thaum CFRP nce mus txog 70% mus rau 80%. Nyob rau tib lub sijhawm, CFRP kuj muaj kev vibration cov yam ntxwv zoo dua li lub teeb hlau. Piv txwv, lub teeb alloy xav tau 9s kom tsis txhob muaj kev vibration. Cov khoom siv hluav taws roj carbon fiber ntau yuav tsum nres li 2 vib nas this, thiab qhov tshwj xeeb muaj zog thiab ib qho kev siv modulus siab.
2. Tsim tau
Cov nplaum carbon cov khoom muaj muaj zog, thiab tuaj yeem xaiv cov khoom tsim nyog raws li qhov yuav tsum tau ua, tsim cov txheej txheem ntawm daim fibers thiab tus qauv ntawm cov khoom siv sib xyaw, thiab siv tus qauv tsim. Piv txwv, yog npaj cov pa roj carbon fiber ntau los ntawm kev quab yuam, lub anisotropy ntawm lub zog ntawm cov khoom siv puas yuav siv tau, kom ua tiav lub hom phiaj ntawm kev txuag khoom thiab txo qhov zoo. Rau cov khoom uas yuav tsum tau ua kom tsis muaj corrosion, lub hauv paus khoom uas muaj kev txhim kho corrosion kuj xaiv tau los tsim.
3. Ua tiav kev tsim kev lag luam
Modularity thiab kev koom ua ke kuj yog ib txoj kev loj hlob ntawm kev kho tsheb. Cov khoom sib xyaw yog yooj yim rau daim ntawv nkhaus ntawm ntau daim duab thaum lub sij hawm molding, ua kom muaj kev tsim tawm ntawm kev tsav tsheb. Integrated molding tsis tsuas yog txo qhov tsawg ntawm qhov chaw thiab tus nab npawb ntawm cov pwm, txo qhov tsawg ntawm qhov chaw thiab lwm cov kev, tab sis kuj zoo heev txo lub voj voog ntau lawm. Piv txwv, yog hais tias cov lus xaus hauv qab ntawm lub tsheb ua los ntawm carbon fiber ntau cov khoom, nws muaj peev xwm paub ntau yam kev molding, tsis txhob muaj kev nyuab siab rau lub zos los ntawm cov khoom siv tom qab thiab tom qab ua cov hlau, thiab kev txhim kho kev ua tau zoo. Kev zoo, txo cov nqi raug tsim.
4. Lub zog hnyav thiab kev cuam tshuam tsis zoo
Cov roj carbon fiber reinforced resin matrix composite (CFRP) muaj ib yam viscoelasticity, thiab muaj lub suab me me sib luag ntawm cov roj fiber ntau thiab hauv matrix, uas yuav ua rau interfacial txhuam. Nyob rau hauv kev ua haujlwm ntawm kev sib raug zoo thiab kev sib txuam ntawm kev sib txuam, CFRP qhov chaw muaj lub zog zoo dua qub thiab kev cuam tshuam tsis zoo. Ntawm lwm tes, qhov tshwj xeeb tshaj yog woven carbon fiber ntau kev sib tsoo energy absorbing qauv ua rau tawg tsam me me nyob rau hauv kev sib tsoo ceev, absorbs ib tug loj npaum li cas lub zog, thiab nws lub zog nqus peev yog 4 mus rau 5 lub sij hawm siab dua li cov khoom hlau, uas tuaj yeem txhim kho lub tsheb. Kev ruaj ntseg los tiv thaiv cov neeg muaj kev ruaj ntseg.
5. Kev tiv thaiv kev txhuam kom zoo
Cov roj fiber ntau reinforced polymer matrix composite khoom yog tsim los ntawm cov carbon fiber ntau thiab cob khoom, thiab muaj tshuaj tsw qab zoo thiab alkali. Lub tsheb uas tsim los ntawm tib yam tsis tas yuav tsum tau kho cov tshuaj anticorrosion, thiab muaj cua tsis zoo thiab kev laus ua haujlwm, thiab lub neej txoj haujlwm feem ntau Nws yog 2 mus rau 3 zaug ntawm cov hlau.
6. Kev kub kub
Cov roj carbon ntau muaj ib qho kev ruaj khov heev hauv qab no 400 ° C thiab tsis hloov ntau ntawm 1 000 ° C.
7. Kev ua haujlwm zoo los tiv thaiv qaug zog
Cov khoom siv roj carbon fiber reinforced cov khoom muaj hindrance rau qhov hnyav tawg loj hlob ntawm cov fiber, thiab nws txoj kev qaug zog tuaj yeem ncav 70% mus rau 80%. Cov qauv ntawm cov roj fiber ntau ruaj khov, thiab lub zog ntawm cov ntaub ntawv puas tom qab lub voj voog ntawm txoj kev nyuab siab nkees yog tsheej lab ntawm cov sij hawm. Tseem muaj 60%, thaum cov hlau thiab txhuas yog 40% thiab 30% feem pua, thiab FRP tsuas yog 20% mus rau 25%. Yog li, qhov qaug zog ntawm cov roj carbon fiber ntau yog tsim rau ntau hom kev siv hauv kev lag luam automotive.
