Dab tsi yog qhov txawv ntawm PA12 CF thiab PA6-CF?
Cov ntsiab lus PA12 CF thiab PA6 CF yog hais txog Polyamide 12 (Nylon 12) thiab Polyamide 6 (Nylon 6) raws li, ob qho tib si txhawb nqa nrog carbon fibers (CF). Qhov sib txawv tseem ceeb tshwm sim los ntawm cov yam ntxwv sib txawv ntawm lub hauv paus PA12 thiab PA6 resins, thiab tseem ceeb, kuj tuaj yeem cuam tshuam los ntawm qhov ntev thiab hom carbon fiber siv. PA12 muaj npe nrov rau nws qhov nqus dej tsawg, ua rau muaj kev ruaj ntseg zoo heev thiab cov khoom siv kho tshuab zoo sib xws hauv cov av noo sib txawv. Nws kuj muaj cov tshuaj tiv thaiv zoo, yoog raws, thiab kev cuam tshuam zoo zog, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias. PA6, ntawm qhov tod tes, feem ntau muab lub zog tensile ntau dua, nruj, thiab siab dua kub deflection kub dua li PA12, ua rau nws tsim nyog rau kev thov cov qauv siv ntau dua, txawm tias nws nqus dej ntau dua. Lwm qhov kev ua tau zoo tshaj -polyamide, PA66, muaj ntau dua thermal thiab mechanical zog tshaj PA6. Qhov kev xaiv ntawm cov nylon resins, thaum ntxiv nrog cov pa roj carbon fiber ntau, nyob ntawm qhov kev xav tau tshwj xeeb ntawm qhov kawg - siv daim ntawv thov, xws li kev ua haujlwm kub, raug dej los yog tshuaj lom neeg, thiab xav tau kev ua haujlwm.
Thaum "CF" feem ntau tuaj yeem qhia txog cov pa roj carbon fiber ntau ntxiv, qhov tseem ceeb ntawm kev ua haujlwm tau ua tiav nrog Long Carbon Fiber (LCF) thev naus laus zis, raws li siv hauvLFT-G®PAB LCFcov ntaub ntawv. Peb LFT-G®Cov ntaub ntawv muaj xws li PA12 LCF, PA6 LCF, thiab PA66 LCF qib, txhua yam muaj cov pa roj carbon fiber ntau ntev dua li cov uas pom nyob rau hauv cov pa roj carbon fiber ntau (SCF) siv zog nylons. Cov carbon fibers ntev no yog tsim los tsim kom muaj kev sib txuam, sib cuam tshuam 3D skeletal network hauv polyamide matrix thaum ua. Cov qauv LCF no yog qhov tseem ceeb, ua kom muaj txiaj ntsig zoo rau kev hloov pauv kev ntxhov siab thiab lub zog dissipation. Yog li ntawd, LFT-G®PA LCF cov khoom sib xyaw ua kom muaj zog tensile zog, flexural modulus (stiffness), kev cuam tshuam tsis zoo (raws li pom hauv cov ntawv thov xws li siab -cov khoom siv ua haujlwm), kev qaug zog, thiab qhov ntev stability, deb tshaj tsis tau tsuas yog unreinforced nylons tab sis kuj lawv luv luv carbon fiber counterparts. Qhov no tso cai rau LFT-G®PA LCF cov ntaub ntawv los ua lub teeb yuag, siab - lub zog hloov pauv rau cov hlau, muab kev sib piv nrog cov qauv tsim thiab kev ua tau zoo ntawm cov thermoplastics.

LFT-G®ntev carbon fiber Nylon66 rau Automotive Solutions
Thaum cov ntawv thov xav tau qhov siab tshaj plaws ntawm cov tshuab ua haujlwm thiab thermal stability,LFT-G®PA66 LCF (Long Carbon Fiber Polyamide 66)yog cov khoom ntawm kev xaiv. PA66 inherently muaj lub zog zoo dua, nruj, thiab siv tas li kub piv rau PA6 thiab PA12. Los ntawm kev txhawb nqa nws nrog ntev carbon fibers, LFT-G®tsim kom muaj kev sib xyaw ua ke uas ua tau zoo nyob rau hauv qhov nyuaj tshaj plaws hauv tsheb ib puag ncig, tshwj xeeb tshaj yog rau hauv qab -- hood Cheebtsam, powertrain ntsiab, thiab siab - cov qauv kev ntxhov siab uas yuav tsum tau muaj kev ua tau zoo ntawm qhov kub siab. Peb cov qib PA66 LCF, xws li LFT-G®PA66 LCF30 lossis LCF40, muab txoj hauv kev rau kev txo qhov hnyav los ntawm kev hloov cov khoom siv hlau xws li txhuas lossis hlau, tsis muaj kev cuam tshuam rau cov yam ntxwv tseem ceeb xws li qaug zog los yog kev ntseeg siab nyob rau hauv thermal cycling. Qhov no ua rau nws zoo tagnrho rau cov khoom xws li cav mounts, kis tau tus mob Cheebtsam, thiab chassis reinforcements qhov kev cia siab yog tsis yog -negotiable.
