Peb Yog vim li cas thiaj xaiv Carbon Fiber Composites
Txij li thaum lub xyoo pua xeem dhau los, carbon fiber tau dhau los ua ib qho ntawm cov ntsiab lus tseem ceeb hauv kev siv cov khoom siv siab heev. Hauv kev siv cov tswv yim, carbon fiber feem ntau ua ke nrog cov ntaub ntawv matrix xws li resins los ua cov carbon fiber ntau, uas tau siv ntau yam. Hauv tsab xov xwm no, peb yuav tshawb txog qhov zoo ntawm carbon fiber composites.
1. Lub teeb yuag thiab lub zog siab: Qhov zoo tshaj plaws paub zoo ntawm cov ntaub ntawv carbon fiber ntau yog lawv lub teeb yuag thiab siab zog. Qhov ceev ntawm cov khoom siv fiber ntau tsuas yog 1.7 g / m³, uas yog 60% ntawm cov hlau alloys thiab tsawg dua 14% ntawm cov hlau. Cov cuab yeej no txhawb nqa cov qauv tsim qauv thiab ua rau nws siv dav hauv cov khoom hnyav. Tsis tas li ntawd, cov khoom siv kho tshuab ntawm carbon fiber yog qhov tshwj xeeb; nws lub zog tensile yog ob peb zaug ntawm cov hlau, thiab nws lub zog tshwj xeeb thiab cov qauv modulus yog qhov zoo tshaj rau cov khoom siv uas twb muaj lawm. Nws kuj boasts zoo heev dabtsi yog khoov lub zog thiab shear zog, zoo raws li cov kev cai siv.
2.Chemical Properties: Qhov sib txawv tseem ceeb ntawm carbon fiber thiab hlau cov ntaub ntawv yog tias carbon fiber yog cov khoom tsis yog xim hlau. Raws li qhov tshwm sim, cov roj carbon fiber ntau muaj cov khoom siv hluav taws xob tsawg, ua rau pom qhov zoo tshaj plaws corrosion kuj thiab kev laus tsis kam, ua rau nws haum rau ntau qhov chaw ua haujlwm. Qhov zoo no txuas ntxiv lub neej ntawm cov khoom siv fiber ntau.
3.Thermal Properties: Kev tsim cov pa roj carbon fiber ntau yuav tsum muaj cov txheej txheem kub carbonization thiab graphitization, uas xav tau kub heev. Yog li ntawd, carbon fiber nws tus kheej tuaj yeem tiv taus qhov kub ua haujlwm siab heev. Txawm li cas los xij, carbon fiber feem ntau ua ke nrog cov resin los tsim cov carbon fiber ntau, uas feem ntau muaj qhov kub thiab txias ntawm ib puag ncig 150 degree. Tam sim no, cov ntaub ntawv thermoplastic carbon fiber ntau tuaj yeem ua tiav qhov kub ua haujlwm ntau dua. Cov ntaub ntawv carbon fiber kuj tseem muaj cov coefficient tsawg ntawm thermal expansion, kom ntseeg tau tias lawv tsis deform vim kev hloov pauv hauv kev ua haujlwm kub, yog li lav qhov ruaj khov.
