Dab tsi yog qhov txawv ntawm aramid fiber ntau thiab carbon fiber?
Xim
Aramid fiber yog ci daj nyob rau hauv lawv lub xeev ntuj, tab sis kuj muaj nyob rau hauv ob peb xim: dub, liab, txiv kab ntxwv, ntsuab los yog xiav.
Cov pa roj carbon fiber yog dub thiab tsis tuaj yeem ua xim. Yog tias koj xav tau hloov cov tsos ntawm carbon fiber, koj tuaj yeem sib xyaw nrog lwm cov ntaub ntawv.
Braiding
Aramid fiber ntau muaj nyob rau hauv tiaj thiab twill weave. Aramid fiber ntau twill weave yog hloov tau yooj yim dua. Aramid fiber ntau weave yuav zoo ib yam thiab muaj kev ruaj ntseg zoo dua.
Carbon fiber ntau fabrics yog woven nyob rau hauv cov kev taw qhia ntawm lub fibers thiab kuj muaj nyob rau hauv dawb thiab twill weaves. Cov pa roj carbon fiber ntau yooj yim weave tsis tshua muaj kev cuam tshuam rau kev txiav. Twill weave muaj qhov ncaj thiab ntev kev sib dhos, thiab hloov tau yooj yim dua thiab muaj zog dua li cov weave.
Cov pa roj carbon fiber ntau thiab aramid fiber ntau tuaj yeem sib xyaw thiab sib xyaw ua ke los tsim cov hybrid fibers, uas txhim kho kev ua haujlwm ntawm cov fibers ua ke los ntawm kev sib koom ua ke.
Chav ntsuas ntsuas
Aramid fibers siv "Denier" raws li chav ntsuas ntawm fiber ntau ntom, cim D.
Qhov loj dua D, cov xov paj coarser, piv txwv li, 75D yog coarser tshaj 50D. Muaj ob hom aramid fibers hauv Suav teb, 600D thiab 1500D.
600D aramid fibers yog qhov nyuaj dua, tsis tshua muaj nqi thiab ua rau ntau tshaj 1500D aramid fibers. Cov khoom tiav yog sib dua, muag heev, thiab xav tias zoo dua.
Cov pa roj carbon fiber yog qhia los ntawm tus lej ntawm cov strands.
Cov pa roj carbon fiber ntau yog ua los ntawm cov ntaub qhwv cov pa roj carbon fiber ntau. 1K txhais tau hais tias ib pob ntawm fiber ntau yarns muaj 1, 000 strands ntawm carbon fiber ntaub, thiab 3K txhais tau hais tias ib nras ntawm fiber yarns muaj 3, 000 strands ntawm carbon fiber yarn.
Yam ntxwv
① Ceev
Qhov ntom yog qhov loj ntawm cov khoom hauv ib chav tsev ntawm qhov ntim. Yog li ntawd, lub denser ib cov khoom yog, qhov hnyav nws xav tias nyob rau hauv tib lub ntim.
Yog tias koj tuav 2 daim Carbon Fiber thiab Aramid Fiber ntawm tib qhov loj hauv koj txhais tes, koj tuaj yeem pom tau yooj yim tias Aramid Fiber daim yog sib dua.
② Lub zog tensile
Lub zog tensile yog qhov siab tshaj plaws uas cov khoom siv tuaj yeem tiv taus thaum nws rub tawm ua ntej nws tawg.
Qee cov ntaub ntawv tsis nkig yuav deform ua ntej tawg, tab sis Aramid thiab Carbon Fibers yog nkig, yog li lawv yuav tawg yam tsis muaj deforming.
③ Kev coj ua
Aramid fiber yog ib qho zoo insulator, thiab carbon fiber muaj hluav taws xob conductivity zoo.
Yam ntxwv
④ Flammability thiab thermal degradation
Cov pa roj carbon thiab aramid fibers tiv taus qhov kub thiab txias thiab tsis muaj qhov melting point. Ob qho khoom siv tuaj yeem siv rau cov khaub ncaws tiv thaiv thiab cov ntaub ntawv hluav taws kub.
⑤ Abrasion tsis kam
Aramid fiber ntau tiv taus abrasion, uas ua rau nws nyuaj rau txiav. Cov pa roj carbon fiber ntau kuj tsis muaj zog hauv kev ua haujlwm.
⑥ Tshuaj tiv thaiv
Aramid fibers yog rhiab heev rau cov acids muaj zog, hauv paus thiab qee cov oxidizing cov neeg ua haujlwm, uas tuaj yeem ua rau fiber ntau degradation. Carbon fiber ntau ruaj khov thiab insensitive rau tshuaj degradation.
Aramid fiber lossis carbon fiber, yuav xaiv li cas?
Ob leeg muaj lawv tus kheej zoo thiab yuav siv li cas nyob ntawm qhov kev xaiv ntawm lawv cov khoom.
Yog tias cov khoom xav tau lub zog siab, ces qhov muaj zog aramid fiber ntau, qhov zoo dua. Tab sis yog hais tias cov khoom yuav tsum tau rigidity siab, ces carbon fiber yog superior.
