Peb yuav tsum paub tias cov ntaub ntawv carbon fiber muaj plaub qhov tshwj xeeb: 300g, 200g, 300g, thiab 200g. Qee cov duab kos thiab cov lus qhia tsim yuav ncaj qha muab cov ntsiab lus ntawm cov ntaub ntawv carbon. Piv txwv li, yog tias cov qauv tsim cov lus qhia qhia meej meej tias cov ntaub ntawv carbon siv 300g thawj cov khoom lag luam, ces peb tuaj yeem piav qhia qhov tshwj xeeb no rau cov chaw tsim khoom.
Yog tias cov qauv tsim cov lus qhia tsis meej meej hais txog qib kev qhia tshwj xeeb ntawm cov ntaub ntawv carbon, peb tuaj yeem txiav txim siab qib ntawm cov khoom siv raws li ntau qhov kev ua tau zoo ntawm cov khoom siv. Piv txwv li, thaum lub zog tensile ntawm cov ntaub ntawv carbon ntau dua los yog sib npaug rau 34{{10}}}0MPa, lub elastic modulus yog 230GPa, thiab elongation yog 1.6%, ces peb tuaj yeem txiav txim siab tias cov pa roj carbon. cov ntaub yog cov khoom lag luam thawj zaug. Yog hais tias lub zog tensile ntau dua los yog sib npaug rau 3000MPa, lub elastic modulus yog 200GPa, thiab elongation yog 1.5%, nws qhia tau hais tias cov pa roj carbon daim ntaub yog cov khoom thib ob; cov gram hnyav ntawm daim ntaub carbon tuaj yeem txiav txim siab raws li qhov tuab ntawm cov ntaub ntawv carbon. Cov ntaub ntawv carbon nrog lub thickness ntawm 0.167mm yog 300g / ㎡, thiab cov pa roj carbon daim ntaub nrog ib tug tuab ntawm 0.111mm yog 200g / ㎡.
Qhov thib ob, xyuas seb daim ntawv xeem puas tiav
Raws li cov khoom siv txhawb ntxiv ntsig txog kev nyab xeeb ntawm cov qauv, cov kua nplaum impregnation uas sib phim cov ntaub ntawv carbon fiber yuav tsum dhau qhov kev ntsuam xyuas kev nyab xeeb. Yog tias daim duab kos yuav tsum tsim lub neej ntawm 30 xyoo, nco ntsoov xyuas seb puas yog daim ntawv qhia txog kev nyab xeeb ntawm impregnation nrog rau kev ntsuas dej noo thiab cua sov; Yog hais tias daim duab yuav tsum tau tsim lub neej ntawm 50 xyoo, lub sij hawm ntev kev nyuaj siab tiv thaiv cov kua nplaum impregnation yuav tsum tau kuaj; cov kua nplaum impregnation tseem yuav tsum tau tshawb xyuas cov ntaub ntawv kuaj tsis muaj tshuaj lom. Ib qho ntawm cov khoom hauv daim ntawv ntsuam xyuas tsis muaj tshuaj lom yog kuaj xyuas cov ntsiab lus ntawm cov tshuaj lom neeg xws li benzene thiab xylene. Yog tias cov khoom muaj daim ntawv qhia no, nws txhais tau hais tias cov kua nplaum impregnation yuav tsis volatilize los yog volatilize tsawg heev teeb meem gases.
Saib xyuas cov khoom muag thiab kev tsim kho
Thaum cov pa roj carbon fiber ntau thiab cov kua nplaum impregnation nkag mus rau hauv qhov chaw, xyuas seb qhov zoo ntawm cov ntaub ntawv carbon fiber yog qhov tsis sib xws. Thaum lub sij hawm tsim kho, koj tuaj yeem hnov txog seb cov colloid puas yooj yim siv. Yog tias cov colloid tuab dhau lawm, cov neeg ua haujlwm tsim kho muaj kev tsim kho tsis zoo, thiab cov colloid yog qhov nyuaj rau nkag mus rau hauv cov ntaub ntawv carbon kom ua tiav cov txiaj ntsig zoo tshaj plaws. Yog tias cov colloid nyias nyias, nws yuav ua rau cov kua nplaum impregnation ntws thiab cuam tshuam rau kev sib txuas.
